EXAIR VariBlast Safety Air Gun

 Air guns can be found in nearly any industrial facility that has a compressed air system within it.  From the maintenance department to the production floor, operators potentially use these for anything from, cleaning up work areas,  to blowing product out of a troubled spot in a process. Handheld blowoffs are often overlooked as a means to increase efficiency yet they are often observed as a means to increase safety.


When evaluating efficiency the length of use for a handheld blowoff is often variable from operator to operator as well as changes even from each use.  Often, operators have several different uses throughout their day that require different levels of force needed to complete the job.  Most safety air guns don’t offer a variable force.  This means operators are full-force for all applications. This means full air consumption whenever that gun is used. EXAIR’s VariBlast Compact Safety Air Gun can help to give operators the adjustability they need.


The VariBlast Compact Safet Air Gun is available from stock with over a dozen options of different Super Air Nozzles as the end defector of the Safety Air Gun.  These are any nozzle up to a 1/8″ NPT thread size.  To couple with these engineered nozzles, we offer stock length extensions up to 72″ (1829 mm)  in length. This makes many applications that are hard to reach easily managed by the operators.


To couple with the extensions and make sure the VariBlast Compact Safety Air Guns all meet or exceed OSHA standards for operator safety, we offer a Chip Shield accessory as well.


If you would like to discuss how to lower the demand placed on your air compressor from blowoffs and want to better experience what true variability as well as what an engineered blowoff is capable of, contact us.

Super Air Amplifiers vs. Electric Fans

 EXAIR’s product offerings contain many products that can be used for cooling. The focus of this blog will be .Super Air Amplifiers These often times get placed in a head to head competition with an electric fan. The best part, they easily come out on top.

When looking at the benefits other than performance and rate of cooling due to air entrainment, many customers prefer the Super Air Amplifier due to the fact there are no moving parts. This comes into play when cooling within in a hard to reach area or within a harsh process is needed.  Placing an electric motor with a blade held on by fasteners may not be desirable from a maintenance standpoint. The Super Air Amplifiers do not require electricity, meaning there is not a motor or bearings that would need to be replaced or inspected.

Another benefit is the small footprint of the Super Air Amplifier. This can also be seen within the video above where the Air Amplifier is shown is able to produce 341 SCFM (9,650 SLPM) in amplified airflow.  This gives the ability to place a small unit inside of a chamber that needs large volumes of air flowed through it.  For instance, a rotomolded part that has a large chamber and it needs surfaces to be cooled in order for the part to hold its shape from the mold rather than warp.  This can also be coupled with the fact that a Super Air Amplifier can be ducted on either the suction or discharge side in order to retrieve cool air or move the warm air out of the area.

Speaking of warm, the Super Air Amplifiers are also manufactured to withstand up to 275°F (135°C) from stock.  Stainless Steel and High-temperature models go well beyond that temp, as seen above. Custom-designed (flanges and different materials are common) versions are also available in short lead-times.

If you would like to discuss the benefits to a Super Air Amplifier further, feel free to contact us.

EXAIR Safety Air Guns: Quiet, Safe, And Efficient Blowoff (Literally) In The Palm Of Your Hand



One of the more popular uses in industry for compressed air is blowing off parts or products, and one of the more convenient methods of doing so is by use of a handheld blow off device.  Given this combination of popularity and convenience, the manufacture and use of air guns is prolific.  They come in all shapes & sizes, and can be made simply and cheaply.

Simple and cheap is fine, in most cases, for the air gun itself.  The part that the air comes out, however, can make all the difference in the world when looking at the cost of operation, environmental effects, and the ability to use the device safely:

  • Cost of operation: the simplest design of an air gun is a trigger device that starts & stops the flow of compressed air through an open discharge.  Throttling this down through a narrow passage increases the velocity of the air flow, making for a more powerful blast of air.  Thing is, this still uses a LOT of compressed air to create that powerful blast…much more than an engineered product. 
  • Environmental effects: By this, I mean noise.  Air guns with a simple open discharge can be LOUD – over 100 dBA in many cases.  It’s been well documented, for a long time, that high noise exposure is bad for operators’ health…and not just in the obvious manner of hearing loss.  Among these other effects are high stress, hypertension, and sleep disorders.
  • Safe use: Open ended blow offs are in violation of OSHA’s directive 1910.242(b,) which regulates the use of compressed air for cleaning purposes.  The big hazard is dead-ending the device into your body…the pressurized air can literally tear your skin open, and inject itself inside.  This creates a dangerous and often life-threatening condition known as an embolism.
Thumb guns are a perfect example of the above mentioned “popularity and convenience.”  They can be made efficient, quiet, and safe by replacing the open end discharge fitting with an engineered product like the EXAIR Super Air Nozzle.  Chip Shields provide additional protection for blown back particulate as well.

EXAIR Corporation offers a diverse line of Safety Air Guns that address all three of these items:

  • Our Super Air Nozzles use a smaller amount of compressed air flow to entrain an enormous amount of “free” air from the surrounding environment to generate a resultant high volume, high velocity air flow.  So you get the same job done, using less compressed air.
  • Another benefit to their specific design is that the entrained air forms a boundary layer that attenuates the sound level of the primary flow, resulting in extraordinarily quiet operation, while still producing a very usable air flow.
  • And…they’re fully compliant with OSHA  because they can’t be dead ended.


If you’d like to talk about efficiency, sound level reduction, and safety in regard to your use of compressed air (hand held or other,) Please Call Us.

Cold Gun Replaces Inefficient and Ineffective Open Pipe

In any machining operation, tool wear is an inevitability. Cutting tools heat up due to friction and this heat contributes to premature tool wear. As tooling wears, poor tolerances and dimensional inaccuracy are common. Additionally, as the cutting edge dulls increased cutting force is required which further increases the amount of heat generated and exacerbates the problem.

A metalworking company on replacing several open-pipe blowoffs on their CNC machines with EXAIR Cold Guns. The open pipes were not effective at keeping the tooling cool, but did a decent job of blowing away chips. Premature tool wear was leading to increased downtime and slowing production as they were frequently having to replace the tooling. Not to mention, these blowoffs were extremely loud and forced anyone on the shop floor to be wearing in-ear and over-the-ear hearing protection.

Each of their CNC machines had one open-line coolant hose or similarly sized open tube blowing compressed air onto the tool. Temperatures in the facility get fairly warm in the summer and this was having little to no impact. They didn’t want to deal with the mess that comes along with coolant, so they looked to EXAIR for a solution. They ended up installing (1) 5215 Single Point Cold Gun System for trial on one of their machines.

Immediately they noticed the reduction in sound as the Cold Gun operates at just 70 dBA, but they also noticed a 20% reduction in tool wear compared to the open-air lines after a short time in operation. It didn’t entirely eliminate the need for hearing protection as there are other processes occurring, but it did lower it to a point that they weren’t forced to use both in-ear and over-the-ear protection.

EXAIR’s Cold Gun was a Product of the Year finalist in 2007. 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!

The Cold Gun has been preset to achieve maximum refrigeration. 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.

Atomization: What is it?

 Atomization is a word that can be seen throughout the industry in rinsing, coating, painting, lubricating, and cooling applications. The act of atomization is simple, we often refer to it when looking at liquids and it means to break up the liquid stream and form fine droplets.  This is essentially a transfer of energy. There are two mainstream methods to atomize liquids for an application, both with their own advantages.


The first is air atomizing. This action is done by combining a stream of compressed air with either a pressurized fluid or a siphon/gravity fed liquid.  The air stream can be combined with the liquid internally to the nozzle, hence Internal Mix Atomizing Nozzles. It can also combine outside of the nozzle, like the External Mix Atomizing Nozzles. We have blogged before on where to use each of these as the reason to select between Internal Mix or External Mix is its own topic.

Benefits to air atomization are, smaller droplet/particulate size is achievable.  The compressed air atomization gives the ability to break up more viscous fluids to get better coverage or thinner layers of spray.  Air atomization also gives the ability to use smaller amounts of liquid because the air takes up a portion of the total flow exiting any nozzle.



The second type of atomizing nozzles are hydraulic atomization. This uses the energy from the liquid being pressurized to break up the liquid stream.  Sometimes there are physical impacts within the nozzle that cause the atomization, other times it is just the liquid leaving an orifice that causes the atomization. This gives the ability to still spray a liquid into droplets of various shapes, dimensions, and flow rates. The lack of compressed air often results in larger droplet sizes as well as higher liquid flow rates. Because the liquid has to be pressurized to certain levels it also becomes difficult to spray higher viscosity fluids through hydraulically atomized nozzles.

Benefits to hydraulically atomized spray nozzles range from stronger spray force for rinsing, ease of installation from not needing to plumb compressed air, ability to flow slurries, or other liquids that may clog or dry due to the design of air atomized spray nozzles.

If you would like to discuss the correct nozzle for your spray application, feel free to contact us.
