EXAIR Cold Gun Overview

By using only a source of compressed air, the Cold Gun and High Power Cold Gun produces a stream of clean, cold air 50° (28°C) below your compressed air supply temperature. The Cold Gun is very quiet at only 70dBA and has no moving parts to wear out. Just supply it with clean, dry compressed air and its maintenance free!

From left to right: EXAIR Cold Guns come with Magnetic Bases for instant installation.

The Cold Gun is pre-set to an 80% Cold Fraction. In other words, 80% of the compressed air supplied to it will exhaust from the cold end of the tube, 20% from the hot end. This prevents the Cold Gun from freezing up during use and optimizes the gun’s cooling capacity. The Cold Gun is an ideal alternative to messy and expensive coolant mist systems. It eliminates the cost of purchase and disposal of cutting fluids as well as worker related health problems from breathing airborne coolant or slipping on wet floors. Replacing a coolant based system also eliminates the need for secondary cleaning operations after milling or drilling. See it in Action here;

The Cold Gun is an invaluable tool for machining a wide range of plastics and other materials that may become contaminated when using traditional coolants or oils. The clean, cold air from the outlet of the Cold Gun keeps the part cool, clean, and dry. Take for example this application where an OEM for the plastics industry uses EXAIR Cold Guns in place of a coolant system.

Are you in need of a new vacuum system or upgrade your new old system? Well now’s the time to do it! Starting March 1st, 2021 and running through May 31st, 2021, we are offering a free Vac-U-Gun system with any order of one of our Industrial Housekeeping Vacuum Systems. Our Vac-U-Gun system is a versatile tool that can help you clean up surfaces and transfer the material from point A to point B. The Vac-U-Gun can also be used as a powerful blow gun simply by unscrewing the generator and flipping it around. Best of all these units have no moving parts meaning they will run almost indefinitely and are maintenance free.

Vac-U-Gun System

Our industrial housekeeping products are designed to either handle dry solids or liquid.

If you need to handle solid material our Chip Vac system is the perfect choice. The system can handle both dry and damp material and transfer it into one of our standard open top steel drum (or use one of your own drums). If you are working with a heavier or abrasive material then look no further then the Heavy Duty Dry Vac which provides superior performance and abrasion resistance for use with materials as garnet, ground glass, blasting and tumbling media.

EXAIR’s Static Eliminator Variety Provides Solutions for Any Industry

As the weather starts to change and the colder dryer months are upon us, static electricity can become a real nuisance.  Machines will start jamming, alignments will be difficult, dirt will collect to surfaces, and hazardous sparks can shock personnel.  EXAIR manufactures a line of Gen4 Static Eliminators, also called ionizers, to remove these nuisances.

Static is generated from non-conductive surfaces being “rubbed”.  This could be caused from going over rollers on a conveyor, stacking product onto each other, sheet feeding, and even peeling away a backing material.  When a non-conductive surface, or insulator, is moved or separated, electrons are “stripped” and redistribute into different areas on the surface.  Static charges are typically measured in kilovolts (KV), or 1,000 volts, and they can be either positive or negative in nature.

The higher the charge, the stronger the static force.  At a 10 KV static charge, a spark can jump one inch (25 mm) from the surface.   You probably felt that shock when working with plastic or non-conductive materials.  EXAIR has a Digital Static Meter to measure the amount of static voltage on a surface.  It is a great tool for finding problem areas in your process as well as determining the effectiveness of the treatment.

Static is dynamic.  The more you rub or move the material, the higher the static charges can form.  Static can also regenerate itself after the charges have been removed.  With higher static charges, the attraction force to other materials is much stronger.  This attraction could be to other products, dust, lint, and even you.  An undesirable effect of static can be seen with dirty surfaces, tearing, alignment, jamming and shock to personnel.  The EXAIR Gen4 Static Eliminators are engineered to remove both negative and positive static charges in an assortment of designs to best fit the application.

EXAIR manufactures nine different products, including Static Eliminators with air assistance to reach farther distances or Static Eliminators without air when surfaces could be disrupted by air flow. The newest product, the Intellistat™ Ion Air Gun is engineered for clean processes, laboratory and test environments.

The Gen4 ionizers are powered by a 5,000 Vac power supply.  The alternating current, AC, will create both negative ions and positive ions.  No matter the kind of static charge is on the surface, the Gen4 Static Eliminators will be able to remove it.  The power supplies come in either a 2 port or 4 port design; so, you can power multiple Gen4 Static Eliminators with one power supply.  The input power is selectable from either 115Vac or 230Vac in both 50/60 hz. An armored and electromagnetic shielded cable connects the power supply to the ionizer in a single wire design. This will help to protect the cable from abrasions, cuts and splits in industrial areas.

The Intellistat Ion Air Gun is powered with a 24Vdc power supply. The Gen4 Static Eliminators and the Intellistat Ion Air Gun have a shockless design, and they are UL Component Recognized and CE compliant.  I will give a brief description of each product that utilizes this rugged design for optimal static neutralization.

Gen4 Static Eliminators with Air:

Super Ion Air Knife

  1. Gen4 Super Ion Air Knife: This product has the best compressed air efficiency in removing static by combining the Super Air Knife with an Ionizing Bar.  The Gen4 Super Ion Air Knife has a 40:1 amplification ratio and uses the laminar air flow to carry the positive and negative ions to the surface.  The laminar flow allows for a quick static discharge in fast conveyance speeds.  They can also remove static from surfaces up to 20 feet (6.1 meters) away.  EXAIR manufactures stock lengths from 3” (76mm) to 108” (2.74 meters).  Some typical applications for the Gen4 Super Ion Air Knife are found in web cleaning, sheeters, pre-paint dust removal, and shrink wrappers.
  2. Gen4 Standard Ion Air Knife: Similar to the Gen4 Super Ion Air Knife, this product has a good compressed air efficiency.  It utilizes the Coanda effect to draw in ambient air at a 30:1 amplification ratio.  They come in stocked lengths from 3” (76mm) to 48” (1.22 meters).  The Gen4 Standard Ion Air Knife are used in similar applications as well as mold releasing, package cleaning, label applications and plastic bag opening.

    Gen4 Super Ion Air Wipe
  3. Gen4 Super Ion Air Wipe: This product blows ionized air in a 360-degree pattern.  They are engineered to remove static and debris from the outside of hoses, plastic pipe, extrusions, and coated wires.  With the split design, the Gen4 Super Ion Air Wipe can easily mount around the product without having to rethread.  They come in two different sizes with a 2” (51mm) and 4” (102mm) inner diameter. The ionized air has a fast static decay for speedy transfers.

    Gen4 Ion Air Cannon
  4. Gen4 Ion Air Cannon: Just like the name, this product will shower an area with ions to remove static. It can reach distances up to 15 feet (4.6 meters).  They are used in multiple areas including pre-paint car bodies, containers, shrink packaging, lenses, etc.  As an Air Amplifier, a small amount of compressed air will draw in a large amount of ambient air.  The ions are carried to the surface from the Gen4 Ion Air Cannon in a laminar air steam.   Once the ions coat the surface area, the air flow can gently remove any debris held by static forces.

    Gen4 Ion Air Gun
  5. Gen4 Ion Air Gun: For manual static removal to target specific areas, the Gen4 Ion Air Gun will work great.  This product comes standard with 10 feet (3 meters) of shielded cable for maximum reach.  An ergonomic air gun is attached to a Gen4 Ion Air Jet to manually remove static in difficult areas and from “shock” zones.  The Ion Air Guns work great for small batch processes used for quality checks or label applications.

    Ion Air Jet
  6. Gen4 Ion Air Jet: Similar to the Ion Air Gun, this product is used for “hands-free” operations. They use a small amount of compressed air to “shoot” the ions onto a surface.  They can be operated with a solenoid valve or foot pedal to blow ions during specific times and situations.  They can easily be attached to a Stay Set Hose and Magnetic Base for best “hands-free” positioning for optimal cleaning.  They work well on small targets for automated systems or inspections areas prior to packaging.
  7.  Intellistat™ Ion Air Gun: This is EXAIR’s newest product that is a lightweight solution for static and particle removal.  The patent-pending air gun comes complete with a 24Vdc power supply and a 6mm compressed air tubing.  There is a red and green LED lights to signify the production of ionized air for visual feedback.  The engineered air nozzles are quiet and OSHA safe.  The emitter point inside that creates the ions can be easily changed for replacement.  The applications range from circuit boards, electronic manufacturing, laboratories, clean rooms, and scientific testing.

The Gen4 Static Eliminators with air can be purchased with kits which will include the power supply (required for ionization), a filter (to clean contamination from the compressed air), and a regulator (to control the blowing force).  In the spirit of compressed air efficiency, EXAIR also offers the Electronic Flow Control, EFC, that uses a photoelectric sensor to turn on the air flow only when the product is under the Static Eliminator.

Gen4 Static Eliminators without Air:

Ionizing Bar
Low cost Ionizing Bars eliminate static cling.

  1. Gen4 Ionizing Bar: This rugged design is for industrial use to remove static cling from flat surfaces. They range from a length of 3” (76mm) to 108” (2.74 meters).  Without the assistance of air, the product has to be within 2 inches (51 mm) from the surface to remove static charges.  The Gen4 Ionizing Bar is shockless and works well in applications where blowing air could be a detriment for the process.  This would include screen printing, labeling, and large printing process.

    Gen4 Ionizing Points
  2. Gen4 Ionizing Point: This single point design is manufactured to remove static on small targets in tight spots.  Utilizing the same rugged design of the Gen4 Static Eliminators, this product can remove static in spot areas and help to stop jams in slitting operations. They can also be panel mounted to neutralize duct air.

If you find that static is creating process problems, wasting time, and costing you money, EXAIR has a large line of Static Eliminators that can help you.  For our U.S. and Canadian customers, we are offering a promotion for online orders for a limited time.  You will receive an AC Sensor, a $59.00 value, for free as a Promotional item from now until the end of March 2021 with a qualified purchase.  How can you not give them a try?  If you have an application, you can contact an Application Engineer at EXAIR to help select the correct model and remove that static nuisance.

The Heavy Duty Line Vac™ moves CO2 Cartridges

Threaded Heavy Duty Family

In trying to cut over-all costs, companies are reviewing process flows throughout their plant.  A CO2 cartridge manufacturer was following that same strategy.  They wanted to move the silk-screening process that marked the outside of the cartridges to a different location.  Currently, the operators would have to pick up bins to move them about 50 feet (15 meters) to the packaging area.  They currently were using blower-type vacuum systems in other parts of their process to move the cartridges through different stages.  But, the bulkiness and noise level of the blower system made them have to find an alternative way; so, they contacted EXAIR.

For their process, they would start with a steel cap.  The metal caps would run through a series of different forms where round punches would “redraw” the metal into a final diameter and thickness.  Once it is finished through this process, it would look like a test tube.  The metal tubes would have the ends heated and pressed with a set of different dies to create the “neck” region.  The “neck” section would be cut and lathe to make a sealing edge.  The cylinders would then go through a washing and drying system to clean.  Once dried, they would travel to the filling station where the cylinders would be partly filled with liquid CO2, and then capped.  The bare steel cylinders would move through a zinc-coating process for protection and appearance.  The filled cartridges would then be inspected by quality control prior to screen printing on the outer diameter.  The finished CO2 cartridges had an outer diameter of ¾” (19mm) (reference photo below).  Once they are printed, the shipping staff would carry them to their department for packing.

The process flow change for this company was to move the silk-screening process about 50 feet (15 meters) from the current position.  With an EXAIR Air Operated Conveyor or Line Vac™, the QC department can transfer the cartridges to the screen printer near the packaging department.  This would stop the needless handling of the filled bins between the printing station and the packaging station.  Not only did this speed up packaging, but it also ergonomically helped the operators from lifting and carrying.

Heavy Duty Line Vac Kit

For the material, distance, and size; I recommended the model 152125 1 ¼” Heavy Duty Line Vac Kit.  This Line Vac is made from a hardened alloy material which makes them resistant to abrasion and wear.  The throat diameter has a clearance of 1” (25mm) which is enough to carry the ¾” (19mm) diameter cartridges.  With a kit, it will also include a filter, regulator and a bracket.  The filter will help keep the Line Vac and the cylinders clean.  The regulator will allow for flexibility in conveyance rates, distances, and speeds.  The bracket helps to mount the Line Vac to a sturdy base for support.    With the small footprint and compact design, it was easy to set up and use as a simple conveyor.

After installation, the Production Manager was amazed by the simplicity of the design and the ease of operation.  He could also reduce maintenance cost without having to change intake filters, check bearings, monitor electrical controls, and replace any failed motors within the blower-type system.  The EXAIR Line Vacs do not have any moving parts to wear; so, they are reliable and long-lasting.  Overall, as compared to the blower-type systems; the cost, set-up, and operation were greatly improved with the EXAIR Line Vac.  They were so happy in meeting the criteria above; the Production Manager mentioned that he would be replacing their existing blower systems when they fail.  And as mentioned above with all the transfers to the different stations, there would be many spots for the EXAIR Line Vac to be used.

If you need to convey materials like cartridges, steel shot or abrasive products, the Heavy Duty Line Vac could be a blessing for you.  Not only can they transfer material safely and quickly, but they also will ergonomically help in saving the backs and knees of your operators.  How can this get any better?  Until the end of October 2020, we are running a promotional ad for our U.S. and Canadian customers.  You will receive a 2” Flat Super Air Nozzle, a $72.00 value, free with qualified purchases online.  If you would like to discuss any of your conveying application, please contact an Application Engineer at EXAIR.  We may have a solution for you.
