NEW from EXAIR! The VariBlast Precision Safety Air Gun

EXAIR’s New VariBlast Precision Safety Air Gun provides a strong, focused blast of air ideal for use in a wide variety of blowoff applications and processes. This CE compliant, lightweight gun utilizes an engineered variable flow trigger that is capable of producing variable force upon the target by simply pulling the trigger. The comfortable, full finger trigger and convenient hanger loop are built-in to the ¼ NPT Safety Air Gun.

Utilizing our range of small Super Air Nozzles (available in both type 316 SS and PEEK plastic for non-marring applications), this gun has the ability to fit into tight spaces while still delivering a strong blowing force. The VariBlast Precision Safety Air Gun is available with an optional 12” or 20” extension (3” extension installed on base model guns) that can also be outfitted with an impact resistant polycarbonate Chip Shield. The air gun body itself is constructed of a high impact polyacetal material for durable use over many years.

All available models of the VariBlast Precision Safety Air Gun come outfitted with an engineered nozzle that cannot be dead-ended, assuring safe usage for your operators and meeting the required standards put forth by OSHA under 29 CFR 1910.242(b). With sound levels as low as 58 dBA with the Model 1808SS, these guns are also well below the allowable limits of noise exposure discussed by OSHA in 29 CFR 1910.95(a).   

Inexpensive air guns are commonly seen in a variety of catalogs and industrial supply companies. Most contain triggers or other components are constantly need replaced. Additionally, their performance is similar to that of an open pipe or tube and can be extremely wasteful, not to mention a potential OSHA violation.

All of EXAIR’s Safety Air Guns will help you operate efficiently & safely. If you would like to discuss your blowoff process with an EXAIR Application Engineer, give us a call. With products available to ship same day from stock, we can get a solution to you as quickly as tomorrow!

Video Blog: New VariBlast Precision Safety Air Gun

EXAIR has a wide variety of Safety Air Guns for safe and comfortable use in all industrial environments. Each Style uses an engineered Air Nozzle that provides superior performance by entraining large volumes of surrounding air. Safe operation is assured along with low air consumption and noise levels.

The newest addition to EXAIR’s Safety Air Gun selection is the VariBlast® Precision Safety Air Guns! They are extremely lightweight and have a focused blast of air that provides remarkable cleaning capability. Designed with a variable flow trigger, the air flow is easily adjustable and able to produce a range of different force values. It comes equipped with a small diameter nozzle and a stock extension that easily fits into tight spaces and delivers a pinpoint, but powerful blast. Two other extension lengths are available at 12” and 20”!

Dead Serious About Dead End Pressure and Chip Guarding – OSHA 1910.242(b)

Compressed air is a very versatile utility that can be used for applications in cooling products to cleaning off workspaces and products. That is where OSHA 1910.242(b) comes into play; this OSHA standard states that compressed air used for cleaning shall not be used except were reduced to less than 30 psi and then only with effective chip guarding and personal protective equipment. This standard is in place because in the event a dead end occurs, the static pressure at the main orifice can potentially force the high pressure air into someone’s bloodstream and cause an air embolism, which if left untreated can impede the flow of blood in the body and lead to a fatality.

Keeping that in mind there are two ways you can go about these cleaning applications and still stay in compliance with the OSHA standard. The first way is to regulate the air pressure in your pipe down to below 30 psig. But for the majority of applications this is not an effective solution as pressure does equate to the amount of force that can be produced from the system. The second solution is to use a nozzle that is engineered in a way the it cannot be dead ended. This means that the nozzle is designed in a way that no matter how hard you try the air coming out of the nozzle will be ejected into the atmosphere and not through skin.

The fins of the Super Air Nozzle allow air to escape and prevent dead-ending the nozzle.

Take EXAIR’s Air Nozzles for example, the fins and orifice placement are designed in a way that allows air escape air into the atmosphere. Once air has exited an orifice into atmospheric conditions the pressure becomes 0 psig but retains the velocity and higher volume from the higher compressed air inlet pressure which produces force.

Model 1210 Soft Grip Safety Air is fitted with an EXAIR Super Air Nozzle. We can also supply it with a Rigid Extension and Chip Shield (right).

In addition, OSHA 1910.242(b) also talks about the use of effective chip guarding, which simply means some method or equipment shall be installed that prevents particles from flying back and hitting the operator. If you look EXAIR’s Safety air guns you will notice that we offer Chip Shields. By simply adding “-CS” to the end of a part number for a Safety Air Gun you can help prevent injuries from flying particles in blow off applications.

If you have any questions or want more information on compressed air safety and OSHA related standards. Give us a call, we have a team of application engineers ready to answer your questions and recommend a solution for your applications.

EXAIR Chip Shield Sizes and Selection

EXAIR has many options when considering Air Nozzles, Air Jets and Safety Air Guns. When considering the safety in using these tools one should consider the extra protection that EXAIR Safety Shields offer. Let’s look at the options and sizes of our Chip Shields.

EXAIR Chip Shields are durable polycarbonate shields that can be used with or without extension pipes. The Chip Shield, as the name suggests, protects the operator from flying debris such as metal chips, shavings and liquid coolants. The use of Chip Shields help meet the requirements of OSHA 1910.242(b) for safe use of compressed air.

If you are ordering a new Safety Air Gun from EXAIR and need a Chip Shield you simply place a “-CS” after the Safety gun model number, For example if you order Model 1210 VariBlast Compact Safety Air Gun (SAG) and want a Chip Shield you would order Model 1210-CS and EXAIR will automatically know the size of the shield and will ship the Safety Air Gun and properly sized Shield. If you would like the same gun with a 12″ extension you would order as such; 1210-12-CS and you will receive the Model 1210 VariBlast SAG with a 12″ Aluminum extension and Chip Shield.

If you have a SAG with an extension pipe and want to add or replace a Chip Shield then we must consider the extension pipe and nozzle NPT. All of the Chip Shields are the same size with the exception of the center diameter and the rubber grommet which will accommodate the NPT size of the Air Nozzle and extension. Here is a list of the replacement shields:

If you have a SAG and do not have an extension pipe or shield we have Chip Shield Kits that will allow you to retrofit your existing gun:

One important note is that SAG’s that are equipped with a Stay Set Hose will not allow for the Chip Shield to be installed. Choosing the correct Chip Shield or Retrofit Kit can be tricky but EXAIR Application Engineers are always ready to help.
