A metal fabricator used a cutting machine to cut different sizes and shapes of stainless steel tubing. The process was automated and the machine would cut two tubes at a time. After the cutting operation, the machine would deposit the tubes into a nearby bin. The operator would then stack the tubes in a wooden container as shown above. Before the tubes could be transported to another department, the operator would have to clean the inside of each tube. The current method was to attach a rag to the end of a rod and pushed it inside the tube to remove any coolant and chips that remained from the cutting operation. Of course, the ability to clean thoroughly with a rag is reduced greatly after a short time of use. The cleaning process was very time consuming, and when the rag was not changed in a timely manner it did not clean effectively. The inside of the tubes would get marred from the excess chips that remained on the rag. This would visually affect the surface finish of the stainless steel. They emailed me the application detail as they were looking for a non-contact way to clean the inside of the tubes.
The first question from the customer was if we could customize our air nozzles to clean the different diameters and shapes that they were cutting. EXAIR has made special air nozzles to accommodate unique applications, but I wanted to first make sure that EXAIR did not have a manufactured nozzle in stock to fit this application. I requested the dimensional information, and the customer sent me the sizes and shapes of the tubes that were ran through their cutting machine. (Reference Table 1 below).
EXAIR manufactures three different sizes of Back Blow Air Nozzles that are designed to clean inside tubing, pipes, hoses, and channels. They can range from internal diameters from ¼” (6.3mm) to 16” (406mm). The 360o rear airflow pattern can “wipe” the entire internal surface clean and can remove coolant, chips, and debris. In reviewing the dimensions from Table 1 above, I was able to recommend just one Back Blow Air Nozzle for all the tubes; even the square and rectangular ones. It was model 1006SS Back Blow Air Nozzle. This 316SS robust designed nozzle can fit inside and clean tubes with internal dimensions ranging from 22mm to 102mm, and it was perfect for all of these tubes.
The customer indicated to me that the tubes were all cut to identical lengths at 550 mm (21.7”). Being that this was a manual operation, I suggested the Back Blow Air Nozzle with our Soft Grip Safety Air Gun. This ergonomically designed Safety Air Gun is designed for hours of use without fatigue. In combination with the nozzle, we are able to add extensions and chip shields. With extensions, EXAIR has a range of lengths from 6” (152mm) to 72” (1,829mm). With the designated length above, I recommended the model 1206SS-24-CS which has the Soft Grip Safety Air Gun, the model 1006SS Back Blow Air Nozzle, a 24” (610mm) extension, and a chip shield.
The configuration allowed for the operator to reach through the tube to clean with only a one-time pass. The CS designation is for a chip shield which will protect the operator from any excess debris and coolant. With the model 1206SS-24-CS, the operator could now pick up a tube, use the Soft-Grip Back Blow Safety Air Gun to remove the debris and coolant from within the round tubes, square tubes and rectangle tubes. Also, they did not have to worry about changing the rags when it got dirty. What an amazing purchase for this company, as they increased the speed of the cleaning operation by 70% without affecting the inside finish of the stainless-steel tubes.
If you need to clean the inside of tubes, hoses, pipes, etc., EXAIR has the perfect nozzle for you, the Back Blow Air Nozzles. EXAIR can attach these nozzles on our VariBlast Compact, Soft Grip and Heavy Duty Safety Air Guns for easy-to-use manual operations. For this customer above, they were glad that they contacted EXAIR about their application. If you require more details, you can share your application with an Application Engineer at EXAIR. We will be happy to 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.

EXAIR’s Heavy Duty Safety Air Gun is designed to provide powerful blasts of compressed air for use in rugged, industrial environments. With a larger 3/8 NPT air inlet compared to our other Safety Air Guns, it allows for higher force and flow values. It comes with a durable cast aluminum body and ergonomic composite rubber grip. The wide curved trigger allows for continuous use for hours without operator’s experiencing fatigue.
All of EXAIR’s Safety Air Guns come with an engineered compressed air nozzle at the tip. This allows you to remain OSHA compliant while still getting the force you need to get the job done. EXAIR’s Super Air Nozzles utilize the coanda effect to entrain large amounts of ambient air from the environment. This ambient air mixes with the primary airstream and is projected towards the target with more force and flow than the supplied compressed air could deliver alone.
Each of the Safety Air Guns is available with extensions fully assembled ranging from 6”-72”. You can simply add a “-“ and the required length, in inches, to the end of any Safety Air Gun Model number.
In addition, they’re also available with a Chip Shield to prevent any chips or debris from coming back into the faces of your operators. Effective chip guarding is another component of OSHA 1910.242(b) in addition to the concerns of dead-end pressure. To add a Chip Shield onto the gun as well, a “-CS” to the standard Model number. For example, a Model 1310-12-CS would be a 1310 gun with 12” extension and a Chip Shield installed. If the application involves blowing off metal chips or shavings, your operators will certainly appreciate this Chip Shield preventing the debris from blowing back all over them.
With EXAIR’s Heavy Duty Safety Air Gun, you can still achieve the high forces required for tough applications without the risk of injuries to personnel. It’ll also keep you safe from any fines associated with an unannounced OSHA visit. Do yourselves and your operators a favor and get one on order today!
