EXAIR’s new VariBlast® Precision Safety Air Guns provide a focused blast of air capable of handling tough jobs with remarkable strength. This CE compliant, lightweight air gun uses an engineered valve for variable flow. It can produce an adjustable force upon a target simply by pulling the trigger to a variety of positions. You can generate higher or lower force as needed for an application.
A comfortable full-finger trigger and a convenient hanger loop are built-in to the Variblast Precision Safety Air Gun. It has a ¼” NPT female compressed air inlet at the base of the handle with an option for a BSP threaded adapter. One of the unique features is the replaceable extensions. They come standard with a 6” (152mm) extension. For greater reach, we offer a 12″ (305mm) or a 20″ (508mm) extension for longer reach. The body is made of high-impact, glass-reinforced nylon to resist breakage. They can also be outfitted with an impact-resistant polycarbonate Chip Shield. In combination with the EXAIR Safety Air Nozzles, the airflow that exits the nozzle can’t be blocked, assuring safe operation and compliance with OSHA standard 1910.242(b). Also, the Precision air gun has a low noise level, only 75 dBA, which is well below the limits of the OSHA noise exposure standard 29 CFR 1910.95(a). EXAIR strives to manufacture safe and efficient safety air guns, and the VariBlast Precision fits that bill.
To expand on efficiency, the engineered nozzles are designed to entrain the free ambient air to add mass to the airstream. With an amplification ratio of nearly 25:1, you only have to use a small amount of compressed air to generate a powerful, focused blast. So, by using less compressed air, it will save you a lot of money. EXAIR offers three different sizes in different materials. The largest is the Nano Super Air Nozzle, which only requires 8.3 SCFM (235 SLPM) at 80 PSIG (5.5 Bar). It is made from type 316SS or PEEK thermoplastic. The PEEK nozzle is great for non-marring applications. The smallest unit is our Atto Super Air Nozzle for very small holes. It also comes in 316SS or PEEK thermoplastic. It only uses 2.5 SCFM (71 SLPM) of compressed air at 80 PSIG (5.5 Bar). For the “in-between” force rating, we offer the Pico Super Air Nozzle in 316SS and PEEK. For the different combinations of model numbers, I created a VariBlast chart below.
A substandard blow-off gun is unsafe, loud, and wastes compressed air. They are subject to dangerous conditions and OSHA fines. EXAIR Safety Air Guns can help improve the situation in all these areas. EXAIR stocks a wide range of safety air guns for almost any blow-off application. We stock units ranging from our smallest size; the VariBlast Precision Safety Air Guns up to our largest size; the TurboBalst Safety Air Guns. From August 1st to September 30th, 2022 for qualified purchases; EXAIR will give a 1” Flat Super Air Nozzle as a promotional item with a purchase of a VariBlast Precision, VariBlast Compact, Soft Grip, Heavy Duty, Super Blast, or TurboBlast Safety Air Gun; a $53.00 complimentary gift. If you have any questions about the VariBlast Precision Safety Air Guns or any of our other safety air guns, you can contact an Application Engineer at EXAIR. We will be happy to help you.
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.
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.
For your dustier applications we offer the Heavy Duty HEPA Vac system, which uses the same vacuum generator as the Heavy Duty Dry Vac but provides a higher level of filtration. The HEPA rated filter meets the requirements of 99.97% filtration at the 0.3 micron level.
If liquids are what you need the Reversible Drum Vac system which can pump 55 gals in 90 secs is an good choice. The Reversible Drum Vac also comes in a High Lift version which can be used to pump liquids that have a much thicker viscosity and move liquids up to 15’ deep. When it comes filtering out solids from your liquid we also have the High Lift Chip Trapper and the Chip Trapper system. The Chip Trapper systems allow you to filter out solids suspended in the liquid; this is perfect for filtering out chips from your coolant tanks for machining.
If you need to clean up both liquids and solids, choose our new EasySwitch Wet-Dry Vac system. The EasySwitch allows you to easily switch the unit from being able to vacuum up solids to being able to suck up liquids (hence the name). All you have to do is remove the HEPA filter from the latch on the lid. There are no tools involved, no springs or cumbersome closures. Switch from liquids to dry materials in less than 15 seconds.
If you have any questions about compressed air systems or want more information on any of EXAIR’s products, give us a call, we have a team of Application Engineers ready to answer your questions and recommend a solution for your applications.

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:
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.
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: 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: 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: 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.
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.
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:
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 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.
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.
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.
