Safety Is Everyone’s Responsibility

Published on by Russ BowmanLeave a comment

That’s a direct quote that everyone at EXAIR hears at our regularly scheduled safety training meetings. While our machine tool operators & assembly technicians spend a lot more time “up close and personal” with devices that can hurt you if not used properly, we all work in the same building with them. That’s why EVERYONE is required to attend those meetings. I like the people I work with, so I REALLY like the level of confidence we all have that the company is looking out for us like that.

The confidence in safety that we have in working at EXAIR is built into our engineered Compressed Air Products as well. Compressed air is downright dangerous, so it’s imperative that you use it safely.

I spent 6 years & 23 days in the United States Navy, so I know full well that you can’t make anything “sailor proof” (no offense to you veterans of other branches, but I once got a letter of commendation from my Commanding Officer for fixing something that I’d broken myself) but I cannot figure out, for the life of me, how to violate OSHA’s Standard on using compressed air for cleaning, with an EXAIR Super Air Nozzle:

OSHA Standard 1910.242(b) says that if you use a compressed air device for cleaning, the static air pressure at the nozzle or opening must not exceed 30 PSI when dead-ended (blocked). Since the air from a Super Air Nozzle comes out of those holes recessed between those fins, there’s a (dare I say it?) sailor proof relief path to make sure that can’t happen.

In fact, all of our blowoff products comply with that standard:

The same design feature (the cap overhanging the body) makes our Flat Super Air Nozzle (left) and our Super Air Knife (right) OSHA Compliant.

Another danger associated with the use of compressed air is the noise level associated with introducing a high pressure gas to atmospheric pressure. If you use airguns or other blow offs without engineered nozzles, you likely know this already. EXAIR engineered Compressed Air Products solve this safety issue as well. Each of the products in the photos above has a very specific feature that causes the primary flow of compressed airflow to entrain a secondary airflow, which results in a much higher total developed airflow. That makes them EXTREMELY efficient — but it also forms a low velocity boundary layer around the hard-hitting air stream in the center, which attenuates the sound level.

In each of these EXAIR engineered compressed air products, the primary air stream following the curved surface causes entrainment. And efficiency. And sound attenuation.

The effectiveness of that low velocity boundary layer is so good that all of our Super Air Nozzles except the very largest ones are compliant with OSHA Standard 1910.95(a) for maximum allowable noise exposure (that limit is 90dBA, so you know.)

In closing, let me reiterate: compressed air is dangerous, so use it safely, and that starts with using safe compressed air products. Like EXAIR’s…we’re all about safety. If you’d like to find out more, I can talk about it all day, and sometimes I do…give me a call.

Revolutionize Your Internal Pipe Cleaning with EXAIR Back Blow Nozzles

Published on by Al WooffittLeave a comment

In industrial manufacturing, cleaning the inside of pipes, tubes, and blind holes has traditionally been a challenge. Standard forward-blowing nozzles often push debris deeper or create safety hazards by ejecting material out the far end. EXAIR solved this problem with their innovative Back Blow Air Nozzles, designed specifically to “wipe” internal surfaces clean by directing airflow backwards toward the operator.

How They Work

These nozzles utilize the Coanda effect to amplify compressed air, entraining surrounding ambient air to create a high-velocity 360-degree cone of air. Because the air is directed back toward the inlet, it pulls coolant, chips, and debris out of the opening rather than forcing them further in.

See the “Back Blow Magic” in Action

Watch this EXAIR video demonstration to see a Back Blow Nozzle clear debris from a plugged pipe in a single pass.

Common Applications

Manufacturers across various industries use these nozzles to improve efficiency and safety. Typical uses include:

  • Machined Part Cleaning: Removing coolant and metal chips from blind holes or internal threads.
  • Hydraulic Cylinder Repair: Cleaning honed bores ranging from 2″ to 16″ in diameter.
  • Tube & Pipe Manufacturing: Clearing debris from long lengths of pipe where forward blowing is impractical.
  • CNC Machining: Quickly cleaning out spindles between tool changes.
  • Electronics Recycling: Removing residual powder from spent toner cartridges.

Key Product Features

  • Material: Manufactured from durable Type 316 Stainless Steel for superior corrosion and wear resistance.
  • Size Range: Available in three sizes—M4, 1/4 NPT, and 1 NPT—covering internal diameters from 1/4″ to 16″.
  • Safety & Compliance: Meets OSHA standards for noise and dead-end pressure.
  • Configurations: Can be mounted on VariBlast, Soft Grip, or Heavy Duty Safety Air Guns with extensions up to 72″ and optional chip shields for operator protection.

Would you like to know which Safety Air Gun model or extension length is best suited for your specific pipe diameter? Give us a call!

On Demand Ionization with the Gen4 Ion Air Jet

Published on by Al WooffittLeave a comment

Static can be a big issue, whether it is shocking operators, causing jamming of machines, or collection of dirt and debris. This is especially true in the colder months. At EXAIR we have a wide range of Static Eliminators that can handle just about every static problem. However, sometimes the issue can be concentrated in smaller areas, and the solution needs to be more precise. For these types of situations, our Gen4 Ion Air Jet is perfect.

The Gen4 Ion Air Jet is a combination of our High Velocity Air Jet, and our Gen4 Ionizing Point. The Air Jet generates a high-speed air stream using a specially designed Coanda profile. This design creates a low pressure at the Air Jet’s entrance, allowing it to pull in surrounding air at a ratio of 5:1. As a result, the Air Jet operates efficiently, producing more ambient air in its output than compressed air. Additionally, thanks to the engineered design, they produce a smooth laminar air stream that can treat a surface up to 15 feet away.

Due to the laminar nature of the airflow, the ions generated by the Ionizing Point will be carried by the air stream all the way to the targeted area. When operated at a pressure of 80psig, the Ion Air Jet is capable of dissipating a 5kV charge in under 0.18 seconds. Although for more sensitive applications, the pressure can be regulated down to adjust the airflow from a blast to a breeze.

Ion Air Jet

In addition to being efficient in its use of compressed air, the Ion Air Jet boasts several other advantages. Due to the engineered design of the High Velocity Air Jet, and the laminar airflow produced, the Ion Air Jet is very quiet compared to other compressed air blow off options. At 82dBA (when operated at 80psig), the Ion Air Jet is well below OSHA’s allowable noise level. It also meets OSHA’s dead-end pressure requirements.

The Ionizing Point used in the Ion Air Jet takes advantage of a shockless design, so it is safe to handle while in operation. As it utilizes the corona discharge method, there are no radioactive materials needed to produce the static neutralizing ions.

In addition to our standard Ion Air Jet Kits, we also have systems that combine our Ion Air Jet with our Stay Set Hoses, making hands-free operation even easier. Whether you are looking for a new solution, or looking to upgrade an existing process, give us a call and see if our efficient, low-cost Ion Air Jets can help solve your static issues.

EXAIR’s VariBlast Precision

Published on by Al WooffittLeave a comment

Air Guns are one of the most common and most trusted tools in manufacturing facilities that use compressed air. There are many options out there on the market, so what makes EXAIR’s VariBlast Precision Safety Air Gun a cut above the rest?

As with all of EXAIR‘s Safety Air Guns, the VariBlast Precision takes safety seriously. All models when used with an EXAIR Safety Air Nozzle are in compliance with OSHA standard 1910.242(b). This means that the airflow that exits the nozzle cannot be blocked, and the static pressure will never exceed 30psig, even when supplied with shop pressure.

The other key safety feature is the low noise level. OSHA noise exposure standard, 29 CFR 1910.95(a), states that protection is needed for continuous exposure to noise levels above 90dBA. Our VariBlast Precision options are all below 75dBA (some configurations are as low as 58dBA!). This is well below the minimum allowable level stipulated by OSHA.

Beyond safety, the VariBlast Precision has many other benefits. Not only is it lightweight and durable, being made of a high-impact, glass-reinforced nylon that is resistant to breakage. It is also easy to use with a comfortable, full-finger trigger and a convenient hanger loop built into it. This trigger also allows for variable flow, giving you a range of forces and flows at your fingertips.

The VariBlast Precision comes standard with a 6″ extension.  For greater reach, we also offer a 12″ or a 20″ option. All extensions are made of Type 316 stainless steel, and are compatible with our Atto, Pico, or Nano Super Air Nozzle. These nozzles come in both Type 316 stainless steel (for durability and corrosion resistance), or in PEEK plastic for non-marring applications. They can also be outfitted with an impact resistant polycarbonate Chip Shield.

If you would like to discuss your blowoff application, and see how EXAIR’s VariBlast Precision, or any of our other Safety Air Guns can help you out, give us a call!
