6 Basic Steps for Good Air Compressor Maintenance (And When to Do Them)

In one of my previous jobs, I was responsible for the operation of the facility.  One of my biggest responsibilities was the air compressor because it supplied pressurized air though out the facility to feed the pneumatic systems.  Like with many industries, the compressor system is the life blood of the company.  If the compressor fails, the whole facility will stop.  In this blog, I will share some preventative maintenance items and schedules for your air compressors.

Because the cost to make compressed air is so expensive, compressed air systems are considered to be a fourth utility.  And with any important investment, you would like to keep it operating as long and efficiently as possible.  To do this, it is recommended to get your air compressor a “checkup” every so often.  I will cover some important items to check as well as a recommended schedule for checking.  Depending on the size of your air compressors, some items may or may not apply.

1. Intake filter:  The intake filter is used to clean the air that is being drawn into the air compressor.  Particles can damage the air pump mechanisms, so it is important to have the proper filtration level.  But, as the intake filter builds up with debris, the pressure drop will increase.  If they are not properly monitored and cleaned, the air flow will be restricted.  This can cause the motors to operate harder and hotter as well as reduce the efficiency of the air compressor.

2. Compressor Oil:  This would be for flooded screws and reciprocating compressors that use oil to operate the air pump.  Most systems will have an oil sight gauge to verify proper levels.  In larger systems, the oil can be checked for acidity which will tell you the level at which the oil is breaking down.  The oil, like in your car, has to be changed after so many hours of operation.  This is critical to keep the air pump running smoothly without service interruptions.

3. Belts and Couplings:  These items transmit the power from the motor to the air pump.  Check their alignment, condition, and tension (belts only) as specified by the manufacturer.  You should have spares on hand in case of any failures.

4. Air/Oil Separators:  This filter removes as much oil from the compressed air before it travels downstream.  It returns the oil back to the sump of the air compressor.  If the Air/Oil Separator builds too much pressure drop or gets damaged, excess oil will travel downstream.  Not only will the air pump lose the required oil level, but it will also affect the performance of downstream parts like your air dryer and after cooler.

5. Internal filters:  Some air compressors will come with an attached refrigerated air dryer.   With these types of air compressors, they will place coalescing filters to remove any residual oil.  These filters should be checked for pressure drop.  If the pressure drop gets too high, then it will rob your compressed air system of air pressure.  Some filters come with a pressure drop indicator which can help you to determine the life of the internal filter element.

6. Unloader valve:  When an air compressor unloads, this valve will help to remove any compressed air that is trapped in the cavity of the air pump.  So, when the air compressor restarts, it does not have to “work” against this “trapped” air pressure.  If they do not fully unload, the air compressor will have to work much harder to restart, wasting energy.

Preventative maintenance is very important, and checks need to be performed periodically.  As for a schedule, I created a rough sequence to verify, change, or clean certain items that are important to your air compressor.  You can also check with your local compressor representative for a more detailed maintenance schedule.

Daily:

  • After stopping, remove any condensate from the receiver tank.
  • Check oil level.

Monthly:

  • Inspect cooling fins on air pump. Clean if necessary
  • Inspect oil cooler. Clean if necessary

Quarterly:

  • Inspect the inlet air filter. Clean or replace if necessary.
  • Check the belt for tension and cracks. Tighten or replace.
  • Check differential pressure indicators on outlet compressed air filters.

Yearly:

  • Replace Air Inlet Filter
  • Replace the air-oil separator
  • Test safety valves and unloader valve
  • Replace compressed air filters
  • Change oil
  • Grease bearings if required

Keeping your air compressor running optimally is very important for pneumatic operations and energy savings.  I shared some important information above to assist.  Another area to check would be your pneumatic system downstream of the air compressor.  EXAIR manufactures engineered products that can reduce air consumption rates.  You can contact an Application Engineer to discuss further on how we can save you energy, money, and your air compressor.

The EXAIR Chip Trapper™ System Extends Machine Coolant Life

Have you realized that you spend too much time cleaning out your CNC machine?  Do you find that It is messy and backbreaking work?  Do you spend too much money replacing the coolant in your system?  If you answer yes to any of these, EXAIR has a product for you; the Chip Trapper System.

EXAIR created this product to reduce the down time and extend the life of your coolant.  This device will save you money and time with productivity, coolant, and repairs.  In this blog, I will go over some of the features and benefits with the Chip Trapper Systems.

EXAIR offers two types, the Chip Trapper and the High Lift Chip Trapper.  They are designed to move fluid into the drum to be filtered, and to allow the clean fluid to be placed back into the sump.  The Chip Trapper works great for quick coolant cleaning at the floor level.  The High Lift Chip Trapper is ideal for cleaning viscous fluids as well as for reservoirs below the floor level.

Both types use a pneumatic two-way pump to move the fluid.  They come in three different drum sizes, 30 Gallon (114L), 55 Gallon (208L), and 110 Gallon (418L). So, you can clean large sump tanks with only one cycle through the cleaning system.  They come standard with a 5-micron bag filter that can hold over 5 gallons of material.

EXAIR can also offer filter bags in 5 other micron ranges from 1 micron up to 200 micron.  And if you are not sure on the other filtration ranges, EXAIR offers a filter sample pack, model 901060-SP, that includes one of each type.

Chip Trapper Cut Away

The Chip Trapper System includes the drum, the two-way pneumatic pump, a drum dolly, a directional flow valve, 10 feet (3m) of vacuum hose, 20 feet (6m) of compressed air hose, a chip wand, a shut off valve, and two additional filter bags.  All you need to do is to attach the Chip Trapper System to a filtered compressed air source.

The High Lift Chip Trapper offers a more powerful pneumatic pump which can fill a 55 gallon (208L) drum in 85 second from 15 feet (4.5m) below.  And, instead of the 10 feet (3m) vacuum hose, it will come with a  20 feet (6m) vacuum hose.

The unique features with the Chip trappers are the abilities to clean the CNC sump very quickly and with less mess.  Also, by using compressed air to pump the coolant in and out of the drum, it will aerate the coolant.  This will reduce bacteria growth and extend the life of the coolant. Thus, saving you money with those more expensive coolants.

Another benefit is that the pneumatic pump does not have any moving parts to wear out.  So, it will last you a long time without worrying about motor failures or loud noises.

You can watch the video of the operation here:

A list of some benefits that you will see if you purchase the Chip Trapper System is as follows:

  • The number of complete coolant change-outs are reduced.
  • The speed to get the CNC machines back operational to make parts.
  • Reduce the number of barrels of coolant concentrate per year.
  • Bacterial growth dramatically reduced as the Chip Trapper aerates the coolant.
  • Filter bags will remove the chip fines and some tramp oils keeping the coolant fresh.
  • Quiet and long lasting
  • A complete system that is easy to use.

As an added note, some CNC machines come with a spindle coolant feature.  This new technology helps in the need to increase speeds and feed rates.  The coolant is pumped to the top of the machine and fed directly through the spindle.  This type of spindle uses a rotary union which allows the coolant to the spindle as it spins at a high rate of speed.  The rotary unions are very expensive and costly to replace.

These spindles are very susceptible to dirty coolant.  If a seal within the rotary union begins to leak inside the machine, you will not be able to diagnose the problem until they have a machine failure.  The Chip Trapper with help eliminate this chance and keep your machine from an extreme expensive breakdown.

When your machine is not operating, your productivity is lost.  The EXAIR Chip Trapper Systems can be that product for you to get you back up and running is a short period of time, extend your coolant life, and keep the area clean and safe.  A win-win proposition in saving money and time.

For U.S. and Canadian customers, EXAIR offers a 30-day unconditional guarantee to try.  And, for a limited time.  an end-user will get a free EXAIR Vac-u-Gun, a $112.00 value, with any purchase of a Chip Trapper or High Lift Chip Trapper.

Different Types of Heat Transfer and How to Calculate their Values

Heat transfer like the name states is the way that heat transfers from one entity to another.  Heat is defined as a motion of molecules.  So, heat is anything above the absolute temperature of 0 Kelvin (-460 deg. F or -273.15 deg. C).  Thus, heat is relative.  Now, for heat to transfer, we need to have a difference in temperatures.  Energy like heat will always travel from the higher temperatures toward the lower temperatures; and there are three major ways that this can happen; conduction, convection, and radiation.  By the first Law of Thermodynamics, energy is neither created or destroyed, only transferred.  In this blog, I will explain each type of heat transfer.

  • Heat Transfer by Conduction

Conduction is about two stationary objects that are in contact.  The vibration of the molecules of one object will affect the vibration of the molecules adjacent to it.  Examples of conduction would be the cold air outside a window pane in a warm room.  Or a hot iron sitting on your wrinkled pants.  The heat from the hotter object will flow to the cooler object.  Thus, the hot object will become cooler while the cool object will become hotter.  This can be explained in Equation 1:

Equation 1 :

Q = -k * A * (T2 – T1) / x

Q – Heat Transfer (Watts)

k – Thermal Conductivity of material (Watts/K-m)

A – Heat Transfer Area (m2)

T2 – Temperature of object 2 (Kelvin, K)

T1 – Temperature of object 1 (Kelvin, K)

x – Material Thickness (m)

 

  • Heat Transfer by Convection

Convection describes heat transfer between surfaces that are in motion. This happens by moving a fluid which can be a liquid or air across an object.  There are two types, free convection and assisted convection.  Free convection is caused by gravity or buoyancy.  The basement will be cooler than the second floor because hot air will rise.  The density of warm air is less than cold air, so it will rise.  As for assisted or forced convection, the fluid will be moved over a surface with a pump, fan, or some other type of mechanical device.  An example of forced convection would be blowing your breath over your cup of coffee to cool.  Another example is the EXAIR Super Air Amplifier.  This device uses a small amount of compressed air to amplify the volume of ambient air.  When blown across a heated surface, it can cool the object quickly.   The calculation for heat transfer by convection is shown in Equation 2.

Equation 2:

Q = h * A * (T2 – T1)

Q – Heat Transfer (Watts)

h – Convective Coefficient (Watts/K-m2)

A – Heat Transfer Area (m2)

T2 – Temperature of object 2 (Kelvin, K)

T1 – Temperature of object 1 (Kelvin, K)

 

  • Heat Transfer by Radiation

Radiation refers to the transfer of heat through electromagnetic waves. Of course, the largest radiation source is our sun.  You can feel the difference when you wear a black shirt versus a white shirt.  Any object will adsorb, reflect, and transmit the radiation at different values depending on the color, surface finish, and material type.  This is called emissivity.  Emissivity, or e, is a coefficient that determines the ability of that object to adsorb the heat from radiation.  Thus, the value of e is between zero and one, and it is unitless.  By definition, 0 < e < 1.  Thus, a black object can have an emissivity of 1.  .  This is important for the EXAIR Cabinet Cooler Systems.  If the panel is outside and in full sun, we would use the color to determine the additional heat that can be absorbed by your electrical panel.  The equation for radiation heat transfer is shown in Equation 3.

Equation 3:

Q = e * A * s * ((Th)4 – (Tc)4)

Q – Heat Transfer (Watts)

e – Emissivity Coefficient

A – Heat Transfer Area (m2)

s – Stefan-Boltzmann Constant (5.6708 * 10-8 Watts/K4 m2)

Th – Temperature of hot body (Kelvin, K)

Tc – Temperature of cold body (Kelvin, K)

Thank you for reading the blog about the three main methods for heat transfer.  If you need to cool products, or remove the heat, EXAIR has many types of products to accomplish this.  You can contact an Application Engineer to discuss any of your applications dealing with heat and heat transfer.

EXAIR Heavy Duty HEPA Vac™ for Dusty, Abrasive or Heavy Materials

Heavy Duty HEPA Vac Family

 

When it comes to industrial vacuums, wouldn’t it be nice to have a durable, long lasting vacuum that is quiet?  There is such a vacuum that has these qualities; the EXAIR Heavy Duty HEPA Vac System.  This vacuum system has no moving parts, no motors to fail, or bearings to wear.  They only require compressed air to operate.

The Heavy Duty HEPA Vac is used to vacuum dusty materials, solid materials, sand, and even heavier materials like steel shot.  The vacuum generator is made from a hardened alloy construction to resist wear and abrasion, and it is designed to create a powerful vacuum level measuring -60” H2O (-15 KPa) at 80 PSIG (5.5 Bar).  To accommodate the multiple types of industrial applications, EXAIR offers the Heavy Duty HEPA Vac Systems in three different options and in three different drum sizes.

The design of the Heavy Duty HEPA Vac is based on, like the name states, the HEPA filter.  HEPA stands for High Efficiency Particulate Air filter.  It has a 99.97% efficiency at 0.3 micron.  We designed the filter to have a large amount of surface area by pleating the media.  This will extend the life of the filter as well as retain very fine dust contamination inside the drum, not in the surrounding air.  The HEPA filter and vacuum generator are uniquely designed to be incorporated in a modified drum lid that will fit onto a standard 55-gallon, 30-gallon, or 110-gallon drum (209L, 114L, or 418L respectively).   It is also quiet, overall the noise level is only 82 dBA at 80 PSIG (5.5 bar).  Measure that against any electric vacuum.

Model 6199

The Heavy Duty HEPA Vac Systems come in three different packages to best fit your application.  The standard package comes with the drum lid described above and a latching ring to attach to your drum.  It also comes with 10 feet (3m) of an anti-static hose, 20 feet (6m) of a compressed air hose, an aluminum chip wand, a hose hanger, a gauge, and a manual operational valve.  For additional protection, the kit will include a Pre-Filter.  This will wrap around the HEPA filter to capture the “big” items to keep the HEPA media filtering the fine particles.  The standard package is available with three different drum sizes.  For example, model 6199 is for the 55-gallon drum (209L), model 6199-30 is for the 30-gallon drum (114L) and model 6199-110 is for the 110-gallon drum (418L).

Model 6299

The next package is the Deluxe Heavy Duty HEPA Vac System.  This option will include all the items in the standard option plus it adds the heavy-duty aluminum tools, a tool holder and a drum dolly.  The upgraded aluminum tools include a floor tool, crevice tool, skimmer tool with detachable brush, and a two-piece double bend wand.  They can be easily attached to the vacuum hose for quick cleaning of material spills.  The Deluxe system is a great option for getting into tight areas, hard-to-reach places, and large floor areas.  This option is also available in three drum sizes.  For example, model 6299 is for the 55-gallon drum (209L), model 6299-30 is for the 30-gallon drum (114L) and model 6299-110 is for the 110-gallon drum (418L).

Model: 6399

If you do not have a drum to use in your facility, no problem.  EXAIR offers a steel drum in the Premium Heavy Duty HEPA Vac Systems.  The Premium package has all the items in the Deluxe package plus a heavy-duty steel drum.  We offer the Premium option for all three sizes as well.  For example, model 6399 will include the 55-gallon drum (209L), model 6399-30 will included the 30-gallon drum (114L) and model 6399-110 will include the 110-gallon drum (418L).

EXAIR offers some additional items to adjust the Heavy Duty HEPA Vac to perform better in other applications.  We have the Filter Protector which is a very inexpensive filter to help protect the HEPA media.  For materials that are very light and buoyant, like powder paint, the Filter Protector can capture much of this material before it gets to the HEPA media.  Another item that we can offer is the 20 feet (6m) anti-static vacuum hose.  If you need to reach at greater distances with your tools to do a thorough cleaning, this hose can be purchased with your system.

If you get tired of throwing away your electric vacuums for burned up motors, you should try the EXAIR Heavy Duty HEPA Vac System.  They will definitely extend the useful life, make it much quieter to operate and vacuum heavier materials quickly.  For U.S. and Canadian customers, EXAIR offers a 30-day unconditional guarantee to try the units.  Also, for a limited time.  an end-user will get a free EXAIR Vac-u-Gun, a $112.00 value, with any purchase of a Heavy Duty HEPA Vac System.  If you want to learn more about our Industrial Housekeeping Products, you can contact an Application Engineer at EXAIR.  We would be happy to help you.

Overview: Adjustable E-Vac Vacuum Generators and Vacuum Cups

Adjustable E-Vac

When it comes to vacuum systems, EXAIR manufactures a very compact and reliable product line called the E-Vac Vacuum Generators.  As a simple vacuum pump, you only need to connect to a compressed air source.  It uses a venturi design to generate high vacuum levels very efficiently.  Since they do not require motors, they are low cost with a wide range of vacuum flows and pressures.  EXAIR offers three different types, the High Vacuum Generators for non-porous objects, the Low Vacuum Generators for porous objects, and the Adjustable E-Vac Vacuum Generators.  In this blog, I will cover the Adjustable E-Vac Vacuum Generators and the variety of suction cups that we provide.

The Adjustable E-Vac gives flexibility to your vacuum system to change the vacuum levels.  The simplicity in the design makes it a great tool for lifting, clamping, chucking, and pick-and-place.  The design also allows for adjustability.  By loosening a lock nut, you can turn the body to reach different vacuum levels.  So, they can be used to move both porous and non-porous materials.  We offer four different sizes with vacuum flows ranging from 5.8 SCFM (164.2 SLPM) to 81 SCFM (2293.6 SLPM).  With the Adjustable E-Vac, you can change the vacuum pressure to go as high as 25” Hg (85 KPa).  Ideal for dialing in the correct vacuum for delicate materials or controlled clamping.

Adjustable E-Vac: How it works

The Adjustable E-Vacs can be packaged in a variety of ways.  The kits help to experiment with different vacuum cups to help determine the best fit for your application.  EXAIR offers two types of kits, the standard kit and the deluxe kit.  The Adjustable E-Vac Kit would include the E-Vac, an assortment of four vacuum cups that are matched to the performance of the Adjustable E-Vac, an assortment of vacuum fittings and 10 feet (3 meters) of vacuum tubing.  The Adjustable E-Vac Deluxe Kit has the items in the standard kit above plus an Automatic Drain Filter and Pressure Regulator with gage.  With both individual units and kits, you can add a muffler to help reduce the noise even more by adding an “M” to the end of the model number.

EXAIR also offers a variety of suction cups to attach to a variety of objects.  We have the small round, the large round, the oval, and the bellows suction cups.  With the different designs, you can pick up a wide range of materials, both porous and non-porous items.  The vinyl material resists wear and distortion for many repetitive cycles.  Here is a better description of each cup below:

Round Cups

Round:  EXAIR has a small and large round style.  This gives us a range of surface areas that we can target to help maximize lift.  They can come either with cleats for heavier lifting and stability or without cleats.  They work great with flat smooth surfaces for horizontal and vertical lifting.

Oval Cup

Oval:  The vacuum is defined by a skinny long area.  EXAIR offers four different sizes.  If you have tight spaces or selectable targets like opening a bag at the top, then the oval shape will work.  They can also handle flat rigid sheets like wood, glass, cardboard, and composites.

Bellows Cup

Bellows:  These suction cups are best suited for uneven or contoured surfaces.  The convolutions around the diameter allow for the cup to collapse and “wrap” around uneven surfaces.  The internal volume is larger than the other cups, so the release and attach times will be extended.  But, for odd surface formations, they can come in very handy.

To combine the Adjustable E-Vac with the Vacuum Cups, how can we determine which ones to use in your application?  Here is some information that we will have to know before getting started.  I like to use anagrams for memory recall, and here is a list that I like to call MOST:

  1. Material
  2. Orientation
  3. Size/weight
  4. Time

Material will tell us if the object is porous or non-porous.  Porous objects are items like cardboard, fabric, cement, etc.  The material can have a rough surface or pores that will allow air to pass through or around the cup.  The Adjustable E-Vac can have the vacuum pressure altered to pick up the material without damaging the surface.   Non-porous objects are items like glass, metal sheets, and plastic.  They have a smooth texture on the surface.  These materials should use the highest vacuum pressure of 25” Hg (85 KPa) to hold the most weight.

Orientation will help us to calculate a safety factor.  EXAIR’s motto has always been safety.  This is important because we want to make sure that the object is secure during movement.  We just need to know if the object is being picked up horizontally only, or if the object is being picked up vertically or rotated in a vertical position.  Then we can apply a safety factor to handle the weight in any orientation.

Size/Weight is simple.  The size is the area that we can pick up the object.  In some instances, we may only have a small target area while in other applications, we will have an entire sheet.  The type of Vacuum Cups is selected by this target area.  The weight will determine the number of Vacuum Cups and Adjustable E-Vacs required to pick up large objects safely.

Time is for applications with cycle rates.  If the job requires a set time to support and release in a known time frame, then we can determine the correct Adjustable E-Vac This can be used for leak checking, clamping, and automatic packaging.

The Adjustable E-Vac Generators are simple, flexible, and very reliable.  As a vacuum pump, they are very compact because they do not use any motors which can wear out.  If you contact an Application Engineer at EXAIR with MOST, we will be able to get the most from your vacuum system.

EXAIR Ion Air Jets Eliminate Static on Benchtops and Small Spaces

Gen4 Ion Air Jets

Static electricity can cause jamming of machines, misalignment, collection of dirt and debris, and shock hazards to personnel.  EXAIR manufactures a variety of Static Eliminators to remove this common nuisance.  In this blog, I will examine our most versatile product within the Static Eliminators; the Gen4 Ion Air Jets.

The Gen4 Ion Air Jets are a modification to the EXAIR Air Jets.  The Air Jets create a high velocity air stream along an engineered Coanda profile.  This profile will create a low pressure at the entrance of the Air Jet to draw in ambient air.  This makes the Air Jet very efficient as it utilizes more ambient air than compressed air at a ratio of 5:1. Also, with the engineered design, we are able to create a laminar air stream to carry ions to the target.

The ions are generated at the exit of the Air Jet by an ionizing point.  This ionizer can create a large amount of positive and negative ions.  This allows for two things to occur.  They are able to eliminate any type of static charge, and they can establish a fast decay rate in removing the static charges.  The replaceable emitter point inside the Gen4 Ion Air Jet allows for an easy, cost-effective way to recondition the unit for years of life.

What operates the Gen4 Ion Air Jet is the power supply.  It is the “engine” behind the ion generation.  EXAIR offers two types; the model 7960 which has two output ports and the model 7961 which has four output ports.  They are very useful to operate multiple units with just one power supply.  They have a selectable input voltage to operate between 115Vac and 230Vac.  The transmission line that connects the Gen4 Power Supply to the Gen4 Ion Air Jet is our high voltage cable.  This cable has an armored coating to resist cuts and wear.  It also has an integrated ground and is electromagnetically shielded.  Together with the Gen4 Ion Air Jet, you get a compact powerful unit that can remove static quickly for spot blowing and cleaning.

Overall, the operation of the Gen4 Ion Air Jet is similar to the Gen4 Ion Air Gun; but, with the Ion Air Jet, it is mainly used for “hands-free” operations.  With a small amount of compressed air, the unit can “shoot” the ions onto a small surface up to 15 feet (4.5 meters) away.  They are very quiet, and they meet the OSHA requirements for dead-end pressure and noise allowance.  They are very easy to control with a regulator to adjust the flow from a breeze to a blast.  The design of the ionizing point is shockless and does not use any radioactive materials.  The applications would include neutralizing static and cleaning objects for three-dimensional parts, screen printing, glass lenses, shrink bands and much more.

The Gen4 Ion Air Jet is the most versatile product in our Static Eliminator line.   It can be permanently mounted or attached to a Stay Set Hose for flexible adjustments and maneuverability.  EXAIR packages the Gen4 Ion Air Jets with other products to make it easy to set-up, control, and operate.  Here are the packages that EXAIR stocks for quick delivery.

Model: 8194 – The Gen4 Ion Air Jet only.  It comes with a 5 foot (1.5 meter) armored and electromagnetically shielded cable.  They are typically used for permanent mounts with a 1/8” NPT male connection, and are generally purchased with the other packages below.

Model: 8294 – The Gen4 Ion Air Jet with a model 7960 Gen4 Power Supply.  This unit is the basic requirement for a permanent mount application.  The Gen4 Power Supply has two outputs, so it can support another Gen4 Ion Air Jet.

Model: 8494 – Gen4 Ion Air Jet Kit.  This kit includes the Gen4 Ion Air Jet, Gen4 Power Supply, a filter separator and a pressure regulator with coupling kit.  This kit allows for cleaning the compressed air before entering the Gen4 Ion Air Jet as well as controlling the air requirements.  So, you will be able to maximize the efficiency of these units.

Model: 8194-9362 – Gen4 Stay Set Ion Air Jet.  We attach the Ion Air Jet to a 12” Stay Set Hose and a magnetic base with shut-off valve.  The magnetic base will hold the Gen4 Ion Air Jet to a steel surface while the 12” Stay Set Hose gives flexibility to direct the ionized air at a specific point.  This product works great if the Ion Air Jet need to be moved into different locations.  (This does not include the Gen4 Power Supply)

Model: 8294-9362 – This is the Gen4 Stay Set Ion Air Jet (as described in the package above) with a model 7960 Gen4 Power Supply.

Model: 8494-9362 – This is the Gen4 Stay Set Ion Air Jet Kit.  Like with the standard units, this package will add a filter separator and a pressure regulator to the model 8294-9362.

Model: 8495-9362 – Gen4 Deluxe Stay Set Ion Air Jet Kit.  The Deluxe Kit includes additional items to the model 8494-9362 package.  It will include a foot pedal and 10 feet (3 meters) of a compressed air hose.  The foot pedal gives this system that “hands-free” operation to turn on/off the air flow to the Gen4 Ion Air Jet to blow air only when you need it.

Model: 8910

Model: 8910 – Gen4 Instant Static Elimination Station.  This is a slight modification to the 8495-9362 Deluxe Kit.  The filter separator and pressure regulator are replaced with an additional 10 foot (3 meter) compressed air line.  Now you can connect from the compressed air source to the foot pedal to the magnetic base.  Once you attach the Gen4 Ion Air Jet to the supplied Gen4 Power Supply, you have a station ready to operate.

Static creates process problems, reduces productivity, and costs you money.  EXAIR manufactures a large line of Static Eliminators that can help you.  If you need a compact, low-cost ionizer to blow off and clean small targets, then the Gen4 Ion Air Jet would be a great option.  You can contact an Application Engineer at EXAIR to see which package would work best for you to remove that static nuisance.
