EXAIR started writing Blogs in 2008. Since then, we have written well over 2000 Blogs. There is a ton of information in our Blog section on the website. There is most likely a Blog or 10 written about nearly each one of our products. These are primarily written by application engineers that know a thing or two about our products. There are also many application Blogs, that may be very relatable to what you are doing. When you journey to our Blog page (or simply click Blog form EXAIR.com), simply type in a key word or two in our search bar. This search bar is located just below the first row of published Blogs on the right hand of the screen, here is a screenshot of that section (right). You can also choose to follow our blog here as well.
As application engineers, we get asked questions every day. Many of these questions are best answered in one (or more) of these 2000+ Blogs. Many times a picture or video can answer your questions much more precisely than a quick conversation or an email. Many times we will send you a blog link to help. Drawing from my own experience, and asking the other Application Engineers for their lists, I wanted to put our most referenced blogs in one helpful location. I’ve categorized these the best that I can, and hopefully this will be a useful resource for you today, and in the future.
OPTIMIZING YOUR COMPRESSED AIR SYSTEM
This is one of the key sections to our blogs. One of our main goals is to help you optimize your system. Here are 6 blogs that go into detail on each of these key points:
This is a product line that has a lot of maintenance questions, probably because these products are used to clean up dirt, and where there is dirt, there can be problems, clogs and leaks:
One of the most common questions we have concerns the Reversible Drum Vacuum (RDV) refurbishment Blog. The RDV is used on the Reversible Drum Vac, and the Chip Trapper products. We offer a refurb service for a fee, but most of the time you can do this on your own by watching and following this blog: Cleaning the Reversible Drum Vac
There are many more blogs and videos at your disposal. This is just a recap of many of our most used, most viewed and most helpful for the day-to-day conversations that happen here at EXAIR. If you have ideas for new blogs – we would love to hear that as well. Please feel free to reach out at any time for more information on any of our intelligent compressed air products.

Over the years you may have read blog posts regarding the EXAIR Safety Air Guns. You can find the blogs here, here and here. 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!
OSHA Standard 1910.242(b) discusses the use of compressed air for cleaning and blowoff. It states that the use of compressed air for cleaning purposes is prohibited if the dead-ended pressure exceeds 30 psig. This phrase means the downstream pressure of the air nozzle or gun, used for cleaning purposes, will remain at a pressure level below 30 psig for all static conditions. In the event that dead ending occurs, the static pressure at the main orifice shall not exceed 30 psi. If it does exceed this pressure, there is a very high potential for it to create an air embolism. An air embolism, left untreated, can quickly impede the flow of blood throughout the body. This can lead to stroke, heart attack, and sometimes death.
So making sure you are in compliance with 1910.242(b) is truly a life and death situation. Most people believe that lowering the pressure to the blow off device is the only method to keep their operators safe from an air embolism. However this can become a problem when you really need the force of greater than 30 PSIG to complete your operation. We at EXAIR want to give you the flexibility to run at any pressure with out the risk of building that 30 PSI of dead-end pressure! We do this with our line of Intelligent Compressed Air® nozzles! All of EXAIR’s Air Nozzles are designed so that the flow cannot be dead-ended. The fins on the Super Air Nozzles are not only useful in amplifying the force by drawing in ambient air, but they also prevent an operator from completely obstructing the airflow.
Another great example of this is our 2″ Flat super air nozzle. The design not only allows the nozzle to amplify the air flow in the blast of air, the over hang will not let the dead end pressure build as it can escape around the edges and bottom!
If you’ve got questions about compressed air safety or have an existing blowoff in place that does not adhere to this OSHA directive, give us a call. We’ll be sure to recommend a solution that will keep your operators and wallets safe!
EXAIR Safety Air Guns use engineered air nozzles for high performance. Inexpensive air guns are sold through many catalogs and industrial supply companies. Most have triggers or other parts that break quickly. Their performance is similar to open pipe, where they simply blow a lot of compressed air. In addition to high air consumption, many produce noise levels that violate OSHA requirements. Some even generate dangerous dead end pressures that can result in serious or fatal injuries if blocked.
EXAIR’s Soft Grip Safety Air Gun has a durable cast aluminum body that is best suited for rugged industrial use. The ergonomic design has a larger trigger for easy operation and a convenient hanger hook for easy storage. Chip Shields for worker safety are available. Extension pipes and stay set hoses for hard to reach areas are also available.
The inefficient use of compressed air for blow-off applications may create problems due to noise level. High noise levels are a common problem for many plants. Compressed air noise often exceeds OSHA noise level exposure requirements, resulting in close proximity.
Air can also be dangerous when the outlet pressure of a hole, hose or copper tube is higher than 30 PSOG (2 BAR). In the event the opening is blocked by a hand or other body part, air may enter the bloodstream through the skin, resulting i a serious injury.
EXAIR Safety Air Guns use our engineered air nozzles which meet or exceed OSHA Standard 29 CFR – 1910.95 (a) Maximum Allowable Noise Exposure and also OSHA Standard 29CFR 1910.242 (b) Harmful Dead End Pressure.
