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.

Spot Cooling

A new solution to an old problem. Heat build up on dry machining operations reduces tool life and machining rates. The Cold Gun Aircoolant System produces a stream of clean, cold air at 50°F (28°C) below supply air temperature. Operation is quiet and there are no moving parts to wear out. It will remove heat to prolong tool life and increase productivity on machining operations when liquid coolants cannot be used.

The Cold Gun is also an alternative to expensive mist systems. It eliminates the costs associated with the purchase and disposal of cutting fluids and worker related health problems from breathing airborne coolants or slipping on wet shop floors.

The standard Cold Gun and High Power Cold Gun incorporate a vortex tube to convert an ordinary supply of compressed air (1) into two low pressure streams, one hot and one cold. The Cold Gun’s hot airstream is muffled and discharged through the hot air exhaust (2). The cold air (3) is muffled and discharged through the flexible hose (4), which directs it to the point of use. Easy mounting and portability are provided through the use of an attached magnetic base (5).

Applications include tool sharpening, drill and cutter grinding, drilling, band saw cooling, plastic machining and setting adhesives. 

EXAIR offers two types, the Cold Gun and the High Power Cold Gun.  The High Power Cold Gun blows twice the amount of cold air as the Cold Gun which doubles the cooling capacity.  They come standard with either a Single Point or a Dual Point Hose Kit with a cone and flat nozzle.  All systems come with a magnetic base and a filter separator.  The magnetic base makes this device simple to attach to your machine and start using.

Enjoy this Summer by Avoiding Heat Related Electrical Problems with Cabinet Cooler® Systems

For many of us, summer contains some of the most enjoyable months coming up in North America. Summer typically brings more time spent outside, basking in the sunshine, lemonade, iced tea, grilling, gardening, fishing, hiking etc.

These enjoyable hot summer months coming upon us can also bring some elevated temperatures within electric control panels – but we have a simple and effective solution to avoid any heat related shutdowns and interference with electrical systems.  EXAIR can eliminate these with our Cabinet Cooler Systems, you just get on with the grilling and basking in the sun.

With freon based coolers, higher ambient conditions make them less effective; and opening the electrical panel to have a fan blow inside creates a dangerous electrical hazard.  For every 10 oC rise above the operational temperature, the life of an electrical component is cut in half.  To reduce loss in production and premature equipment failures, it is important to keep your electrical mechanisms cool.  The EXAIR Cabinet Coolers are designed to do just that.

How the EXAIR Cabinet Cooler System Works

How does the Cabinet Cooler work? 

Cabinet Coolers are powered by an EXAIR Vortex Tube which only uses compressed air to generate cold air.  They do not have any moving parts, Freon to leak, or refrigerant compressors to fail.  These simple, but effective, cooling devices can be used in the toughest of environments.  With the Vortex Tube as the “engine”, the reliability of the EXAIR Cabinet Cooler is unmatched and makes it an easy choice for cooling electrical panels.

What NEMA ratings does EXAIR offer? 

To match the same integrity as your electrical panels, EXAIR offers three different types of NEMA ratings that are UL listed and CE compliant.  NEMA 12 is dust and oil tight, and can be related to the IEC standard, IP54.  NEMA 4 is dust and oil tight as well as splash resistant for indoor and outdoor use.  The NEMA 4X is the same as the NEMA 4 except it is made of stainless steel for corrosive areas and aggressive wash-down environments.  Both the NEMA 4 and 4x corresponds to an IP66 rating.  EXAIR Cabinet Coolers are easily installed and can match your electrical panel to keep the electrical components safe inside.

What size Cabinet Cooler do I need? 

EXAIR makes it easy to get the proper cooling with the Cabinet Cooler Sizing Guide.  This guide goes over the important information to determine the external and internal heat loads.  It also indicates the proper NEMA type and electrical requirements for easy installation. The cooling power ranges from 275 BTU/hr to 5,600 BTU/hr, and with the filled-out form, we can make sure that the correct model is used.

Thermostat- Controlled System

What types of systems are offered? 

EXAIR offers a continuous operating system and a thermostat-controlled system.  The continuous operating system includes the selected Cabinet Cooler, a filter, and a cold air distribution kit.  The system will continuously cool until it is manually or automatically turned off.

The thermostat-controlled system is the most efficient way to operate a Cabinet Cooler.  This system comes with the selected Cabinet Cooler, filter, cold air distribution kit, a thermostat and an electrical solenoid valve.  The system is designed to operate only when cooling is needed.  The thermostat controls a solenoid valve, and it is preset at 95°F (35°C).  The thermostat can be easily adjusted to match other desired temperatures.  The solenoid valves come in three different voltages, 120Vac, 240Vac, and 24Vdc (which ever voltage is easily accessible).  With the thermostat-controlled system, you do not have worry about the system operating during off-peak conditions or cooler seasons.

EXAIR NEMA 4X 316SS Cabinet Cooler System with Electronic Temperature Control installed on control panel in a pharmaceutical plant.

What other options does EXAIR offer with the Cabinet Cooler Systems? 

For better temperature control, EXAIR can replace the standard thermostat and solenoid valve with the ETC, or Electronic Temperature Control.  It is a digital temperature controller with a LED screen for precision monitoring and adjusting.  The controller has easy-to-use buttons to raise or lower the desired internal cabinet temperature.  Once set, the ETC will hold the temperature to +/- 1 oF (+/- 0.5 oC).  The LED displays the internal temperature for continuous monitoring.  The ETC comes complete with the controller and a solenoid valve in two different voltages, 120Vac and 240Vac.  The ETC is a great option for real-time accurate measurements for your panel cooling.

Another option that EXAIR offers is the Side Mount Kit.  They are used to mount the Cabinet Coolers on the side of the electrical panel.  They are manufactured to match the NEMA rating of the Cabinet Cooler.  If you have limited space, don’t worry.  The Side Mount Kits gives you more areas to mount the Cabinet Cooler to your electrical panel.

What about harsh environments? 

  • With elevated ambient temperatures like near ovens, the high temperature version would be your option. The HT Cabinet Coolers work in temperatures from 125 oF to 200 oF (52 oC to 93 oC respectively).  With refrigerant coolers, the elevated temperatures make it very difficult to cool effectively.  But with the EXAIR HT Cabinet Coolers, the high temperature will not affect the ability to blow cool air.
  • If the environment is extremely dirty with lint, fibers, debris, etc., EXAIR offers an NHP, or Non-Hazardous Purge, version. The solenoid valve is designed to allow 1 SCFM of compressed air into the panel to keep a slight positive pressure. With the NHP Cabinet Coolers, the ingress of any fine particles into your electrical panels are eliminated.
  • For food and beverage, pharmaceutical, and corrosive type of applications, EXAIR can offer NEMA 4X Cabinet Coolers made from 316SS material. With the high corrosion resistance, the 316SS Cabinet Coolers will continue to operate without degrading in tough environments.
  • In Class I, Class II, and Class III hazardous areas, EXAIR has the HazLoc Cabinet Coolers. They are UL classified and can work with X-type and Z-type purge systems for the thermostat-controlled system.  The solenoid valves are also designed to be located in these areas with the same three different voltages.  The Hazloc Cabinet Coolers can be sold as a continuous operating system as well.

    Model 7929 EXAIR AC Sensor – FREE to end user customers when purchasing ANY EXAIR Cabinet Cooler System

Electrical shutdowns are expensive and annoying.  If you have interruptions from high internal temperatures, EXAIR Cabinet Coolers are a great solution.  They can be installed quickly and easily.  With no moving parts or costly preventative maintenance needed, they can operate for decades in keeping your electronics cool.  For our U.S. and Canadian customers, we are offering a promotion.  You will receive an AC Sensor, a $58.00 value, for free as a promotional item from now until the end of August 2020 with a qualified purchase.  How can you not give them a try?  If you have any questions about Cabinet Coolers or the Sizing Guide, you can contact an Application Engineer at EXAIR.  We will be happy to help.

Cold Gun Aircoolant System™: Overview

EXAIR Cold Gun Promotion

Many machining companies like to use coolant to flood their parts for drilling and milling operations.  But what if there was an alternative way?  EXAIR has an interesting technique by using cold air instead of coolant.  This would help save time by eliminating cleaning and drying of parts as well as reducing coolant waste.  EXAIR calls this product our Cold Gun Aircoolant System™.

How the Cold Gun Works

The Cold Gun Aircoolant System uses a Vortex Tube to produce a cold air stream at 50oF (28oC) below supply air temperature.  Heat is one of the major causes for dulling and premature failures for tools, and by blowing cold air, it will reduce the heat buildup in tools while also removing the chips from the surface.  The EXAIR Cold Guns are very compact, portable, and easy to use.  Just attach compressed air to the unit, and it will produce cold air.  Since they do not have any moving parts, Freon, or electricity to operate, it is maintenance-free and long-lasting.  And, EXAIR offers a 5 year “Built To Last” warranty against defects in workmanship and materials.  These systems will extend tool life, improve tolerance control, and increase production rates by replacing coolant during milling, cutting, and drilling operations.

The benefits of using the Cold Gun Aircoolant System extends beyond reducing tool wear, finishing with dry parts, and surface smearing.  It can be used in applications where liquid coolant cannot be used.  This would include wood products, MDF, and plastics.  As insulators, cutting tools will get extremely hot as the material will not remove any heat like with metal chips.  Thus, machining can soften, gall, or burn the surface of the material; allowing only slow speeds for operations.  The cold air from the Cold Gun can keep the tools sharp and the materials hard and firm.  With plastic materials, this is very beneficial as it will keep the plastic rigid for tight tolerance machining.  If burnishing or scoring is occurring, the Cold Gun Aircoolant Systems can help to improve the surface finish of your product.  Other applications would include surface grinders, laser cutters, hot melt setting, and band saws.  The Cold Gun Aircoolant Systems are a low-cost solution that can do a lot of great things to improve processes.

Cold Gun Aircoolant Systems

EXAIR offers two types, the Cold Gun and the High Power Cold Gun.  The High Power Cold Gun blows twice the amount of cold air as the Cold Gun which doubles the cooling capacity.  They come standard with either a Single Point or a Dual Point Hose Kit with a cone and flat nozzle.  All systems come with a magnetic base and a filter separator.  The magnetic base makes this device simple to attach to your machine and start using.  The four models that EXAIR stocks are in the photo above.

EXAIR is running a promotional offer on the Cold Gun Aircoolant Systems.  From now until the end of yr2019; if you buy a Single Point Cold Gun System or a Single Point High Power Cold Gun System; model W5215 and model W5230 respectively, we will include a free model 5902 Dual Point Hose Kit, a $39.00 value, with your system.  And as always, EXAIR offers a 30-day unconditional guarantee for our customers in the U.S. and Canada to try them out.  If you have an application that you believe would be better served with an EXAIR Cold Gun Aircoolant System™, contact an Application Engineer.  And take advantage of our promotional offering by receiving a FREE Dual Point Hose Kit.
