It doesn’t say things like we have 99.9% on time shipping for 23 years in a row, or that we constantly add new products to our 15 product lines which help you solve even more problems in your facility. It doesn’t say order by 3pm and you can expect same day shipping or any of the nice things our customers say about their experience with us:
“Great Service!!!” – Carlos H., metal packaging manufacturer
“Very prompt and answered all of my questions!” – Michael W., connector and sensor manufacturer
“Very professional, knowledgeable” – Jose P., CNC machining and metal services
“Great info about [the] product I asked about…..very very helpful” – Joe O., home air conditioner manufacturer
But it does say a lot of other things you can expect when doing business with EXAIR.
EXAIR has designed a new nozzle called the Super Air Scraper. This nozzle combines a scraping blade with our 2” Flat Super Air Nozzle. It creates a mechanical force with a compressed air force to remove stubborn sticky material. This patent-pending nozzle can be added to the EXAIR Soft Grip Air Gun to create a powerful scraping tool.
Let’s breakdown the nozzle. The 2″ Super Air Scraper nozzle is a model 1144 which has a ¼” NPT female connection. The model 1144-A includes a ¾ – 32 UN adaptor for connecting to the Soft Grip Safety Air Gun extensions. The scraper can be changed when worn with a replacement blade; model 902007. To add flexibility to the Super Air Scraper, a shim set, model 1132SS, can be used to modify the blowing force. With these combinations, the nozzle complements the scraper as an effective way to clean with compressed air.
To get pressurized air to the nozzle, EXAIR attached the 1144-A Super Air Scraper nozzle to the Soft Grip Safety Air Gun. This gives a comfortable and ergonomic way to use and operate this product. We offer different extensions for hard-to-reach applications ranging from 6” (152mm) to 72” (1,829mm) in length. With the extensions that are 36” (914mm) and longer, EXAIR installed an additional foam grip sleeve. This gives additional leverage for scraping material at a distance like floor level. Chip Shields are also offered to prevent blow-back onto the operator. You can view the details of the new product at this link on our website: Soft Grip Super Air Scraper.
To give some ideas for applications, the Soft Grip Super Air Scraper can be used for removing tape, gasket material, caulk, adhesive, paint, labels, and more. With the addition of air, the detached material is blown away during scraping, keeping the area clean to target the remaining “stuck” material. If gummy or flaky substances are a nuisance for workers, the Soft Grip Super Air Scraper can keep the machine or work station clean and operational.
Just like all cataloged items for EXAIR, we stock these parts for same day shipment with orders placed before 3 p.m. EST. We offer a 30-day unconditional guarantee to allow you to see how great this product can work in your application. If you have a sticky, flakey, or greasy substance that needs to be removed, the Soft Grip Safety Air Scraper is up to the challenge. If you have any questions about the product or your “gummy” situation, you can contact an Application Engineer for help.
One of the easiest ways to find out if your compressed air guns are safe for operation is by looking at the nozzle. First, take your current compressed air gun and disconnect it from the compressed air line. Second, look directly into the end of the nozzle where the air comes out. If you can see the inside of the nozzle, then your air gun or blow-off device is unsafe. Nine out of ten compressed air guns are considered to be dangerous. In this blog, I will go through the dangers and violations of compressed air guns and nozzles that are very common in the market place.
Occupational Safety and Health Administration, OSHA, is an organization that enforces standards for safe and healthy working environments. They have training, outreach programs, and educational assistance for manufacturing plant. But, they will also enforce these standards with heavy fines for violations. The two most common violations with compressed air guns and nozzles are 29CFR 1910.242(b) for dead-end pressure/chip shielding and 29CFR 1910.65(a) for maximum allowable noise exposure. If you are unfortunate in receiving an audit, the OSHA agent will target your compressed air guns and blow-off devices.
Here is the first example of a nozzle that I would like to discuss. As you can see, there is only one opening where the air can come out from the nozzle. Other types of nozzles that would fall into this category will include copper pipes, extensions, or worn nozzles. They are dangerous as the compressed air cannot escape if it is blocked by your skin. An air embolism could occur within the body which can cause bodily harm or death. If operated above 30 PSIG (2 bar), these nozzles would violate the OSHA 29CFR 1910.242(b) for dead-end pressure. This is a hazard which can be avoided by using EXAIR Super Air Nozzles and Safety Air Guns. The nozzles are designed to utilize fins to allow air to escape and not penetrate your skin. With EXAIR products, you will not violate this standard even if you go above the 30 PSIG (2 bar).
To counteract the dead-end pressure violation, some nozzle manufacturers created a hole through the side of the nozzle (Reference photo below). This will allow for the compressed air to escape, but, now the issue is noise level. With an “open” section in the nozzle, the compressed air is very turbulent and very loud. They state that 70% to 80% of all hearing loss within a manufacturing plant is caused by compressed air. For this, OSHA 29CFR 1910.65(a) was created to show the maximum allowable noise exposure. This chart shows the time and noise limits before requiring hearing protection. The EXAIR Super Air Nozzles are designed to have laminar flow which is very quiet. With our typical Safety Air Gun, model 1210, the sound level is only 74 dBA; well under the noise exposure limit for 8 hours.
Why do I bring these points up? Because safety is everyone’s responsibility. The National Institute for Occupational Safety and Health, NIOSH, has an overview of how to handle hazards in the workplace. They call it the Hierarchy of Controls (click). This is a means to best protect workers from dangers. The most effective way is by eliminating the hazard or substituting the hazard. The least effective way is with Personal Protective Equipment, or PPE. For your unsafe compressed air nozzles and guns, EXAIR can help by substituting the hazardous air gun and nozzle with an engineered solution designed with safety in mind.
In my opening statement, I explained a quick and easy method to determine if your compressed air guns are dangerous. To keep your company compliant and safe, EXAIR offers a variety of different types of nozzles and Safety Air Guns to best fit your requirement. If you find that you are using hazardous blowing equipment, you can contact an Application Engineer to find a safe and effective alternative.
Over the last several weeks, you may have read blog posts regarding the EXAIR Safety Air Guns. You can find the blogs here, here and here. We are also in the midst of a Safety Air Gun Promotion, please click HERE for more details on how you can get a free 1″ Flat Super Air Nozzle. Today, I want to review a few available options for the Safety Air Guns.
Protect Workers From Flying Debris! – Chip Shields are durable polycarbonate shields that protect the operator from flying debris often seen when blowing off chips from machined parts. They are also useful to prevent coolant from splashing back, creating a mess during drying processes.
The Chip Shields are available for EXAIR’s VariBlast, Soft Grip, and Heavy Duty Safety Air Guns. The Chip Shield can be used on Safety Air Guns with or without an aluminum extension. They may be purchased as part of a new air gun system, or retrofitted as a Chip Shield Kit. Consult an Application Engineer for selection assistance.
If you have a blow-off process where the air is to be directed at a distance away from the operator, or into a hard to reach location an extension is the solution. Available in lengths from 6″ (152mm) to 72″ (1829mm), with sizes as shown below, a length to meet most any requirement can be found. To add an extension to an air gun, simply add -xx to the current part number.
And, if you need a 12′ coiled air hose, to use with your Safety Air Gun, we have them available and in stock. Available with 1/8 NPT, 1/4 NPT or 3/8 NPT male end swivel connections. Avoid tangled and messy air lines and keep things neat!
Inexpensive air guns can be picked up just about anywhere, and you generally get what you pay for. Most will be very noisy and waste lots of compressed air. And many will be unsafe, violating two of OSHA’s standards put in place to protect worker safety. The first is Standard 29 CFR 1910.95(a) which sets limits to the maximum noise exposure, and the second is Standard 29 CFR 1910.242(b) which says that the nozzle cannot be dead-ended, or exceed a 30 PSIG pressure limit.
These guns may seem like a perfect fit for a handheld blowoff application. The truth is, the cost saved up front will easily be paid throughout the cost of ownership. This is due to the lack of an engineered nozzle which meets and exceeds the OSHA standards mentioned above. The “cheap” guns often have a cross drilled hole to meet or exceed the OSHA standard for dead-end pressure. While this may be true, it causes a large wind sheer which escalates noise levels to well over the allowable noise level exposure set by OSHA. These tips sometimes offer large force outputs because they are equivalent to an open pipe. We have publicized numerous times about how an open pipe blow off does not permit pressure to be utilized all the way to the point of blowoff, and is also a waste of energy.
In order to determine how much compressed air your current blow guns utilize, the level of noise they product, and the sound level they produce, consider taking advantage of the EXAIR Efficiency Lab. The Efficiency Lab is a free service that you can read more about here.
An EXAIR Safety Air Gun is engineered and designed to comply both of the OSHA standards mentioned above, ensuring safe operation for company personnel. On top of the safety designed into the guns, we also ensure all of our guns are efficient by offering only engineered nozzles on them.
EXAIR offers (4) types of Safety Air Guns – the VariBlast, the Soft Grip, the Heavy Duty, and the Super Blast. Each type of Safety Air Gun is offered with a plethora of nozzles, as well as varying length extensions, with or without the Chip Shield.

Inexpensive air guns can be purchased just about anywhere- online, via catalogs, and through industrial supply companies. Typical quality is less than ideal – broken triggers, leaky valves – a short lifespan in an industrial setting are merely a few of the issues observed. Most are loud and inefficient – they just blow large amounts of compressed air, and at noise levels that violate OSHA requirements. Some may even generate dangerous dead end pressure situations that that can result in serious or fatal injuries if blocked.
EXAIR’s Safety Air Guns have been engineered and designed to eliminate these issues. They are durable for use in industrial situations and comfortable to use for extended periods of time. With an EXAIR engineered air nozzle, each model provides top performance by entraining large volumes of surrounding air into the air-stream. Operation is assured to be safe along with low compressed air consumption and noise levels. Due to the design, the airflow that exits the nozzle cannot be blocked, as required by OSHA Standard 29 CPR 1910.242(b).
The VariBlast style of safety air gun offers variable force based on the range of trigger pull. Force can be varies, form a light breeze, to full force maximum output. This cast aluminum air gun can be fitted with any of the EXAIR 1/8 NPT engineered air nozzles.
The Soft Grip style of safety air gun has a durable cats aluminum body suited for rugged, industrial use. The ergonomic design has a soft vinyl cover, a large trigger for easy operation, and a hanger hook for easy storage.
The Heavy Duty style of safety air gun is powerful with a durable aluminum cast body and ergonomic composite rubber grip, best suited for rugged industrial environments. Hours of fatigue free operation are possible.
With all of the Safety Air Guns styles, Chip Shields and Extension Pipes are available, from 6″ to 72″ in length.
With many nozzle options, from a whisper quiet 58 dBA and 2.5 SCFM of flow up to 60 SCFM and 87 dBA (still below the OSHA 8 hour noise level threshold) there is a model that will fit practically any application. Application Engineers are available by phone, email, and chat to review your specific blow off needs, and help to select the best possible solution available.
