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.

Have you ever dipped your hand into a warm bath of paraffin wax? You can feel your hand relaxing. When you pull it out and begin to peel the wax away you can already tell how soft and refreshed your hand feels. And then someone gives you a hand massage while you sit there in complete bliss, your hand completely relaxed and rejuvenated. Well, this is not at all how the Soft Grip Super Air Scraper makes your hands feel. But the Soft Grip handle is very comfortable and does feel better than any other option on the market.
The Soft Grip handle is ideal for continuous use without causing fatigue. The design keeps your hand in a comfortable position and the large trigger allows an easy pull with one finger or all of them. This is built to endure the toughest industrial environments, and it even comes with a convenient hangar hook for easy storage.
Once we get past the comfortable handle, we move down to the purpose. The Air Scraper portion will assist in removing some of the toughest debris found in industrial facilities. The patented design uses the scraping blade along with powerful compressed air flow. This is perfect for any of those sticky substances like caulk, sealants, gaskets, adhesives, tape, paint stickers, labels, grease, lubricants, and so much more. This will help you keep your machining tables, and assembly stations clean and functional.
The scraper is made of corrosion resistant steel and is attached to a 2″ Super Air Nozzle. It is very formidable to provide the strength necessary for the toughest scenarios. This comes with a 3/4″ extension for those close up needs, but we offer extensions for this from 6″ to 72″ long so that you can reach table tops, walls, inside machines, and floors.
Please reach out to us at anytime with questions about the Soft Grip Super Air Scraper, or any of our other amazing products.

The energy rebates described below are available throughout the country, not just Indiana – but here is the latest example.
Here in Cincinnati we border two states, our bypass loop actually goes through both of them, Kentucky and Indiana. Indiana is a state that most may fly over or if you are going anywhere it may be to go to Indianapolis, myself, I have a few ties to the state elsewhere, from racing motorcycles at Putnam Park west of Indy, my niece attending the prestigious Rose-Hulman Institute of Technology, to my previous career where I installed CNC machines in various parts of the state. While many may think the state is a giant wind power farm, there is a great deal of industry and manufacturing throughout the state including pharmaceutical and medical devices, mining, and transportation. The leading energy provider for the state, Duke Energy, also supports these manufacturers with programs to incentivize (through rebates) products which increase efficiency.
We’ve mentioned energy rebates previously and I have recently had the chance to help a customer with their energy rebate. More often than not, these rebates are an after thought, I hope that after reading this we can help you to check with your local service provider to see if they offer a similar process – they are available throughout the country from MANY electricity providers. The process for this customer was based off purchasing a single Soft Grip Safety Air Gun with Stainless Steel Mini Super Air Nozzle. The rebate was focused on the engineered air nozzle. For a 1/8″ NPT nozzle, it must consume 10 SCFM or less at 80 psig inlet pressure. For a 1/4″ NPT nozzle, they have to consume 17 SCFM or less at 80 psig. The fact the nozzle was assembled onto a Soft Grip Safety Air Gun enabled the customer to apply for a rebate for the full cost of the whole air gun.
The value of the rebate for Indiana where Duke is the energy supplier is $40.00 USD per engineered nozzle installed. The rebate is capped at 75 percent of the project cost in Indiana. The current cost of the 1299SS is $134.00, which enables this customer to the full $40.00 for each Safety Air Gun with Mini Super Air Nozzle they install. This is one of the simplest prescriptive rebates in the Duke Energy program. The main focus here is to conserve compressed air which ultimately puts more energy available to the rest of the grid. The engineered nozzle prescriptive rebate is just one way that Duke Energy customers in the state of Indiana can save.
If you are in the state of Indiana (OR ANYWHERE ELSE IN THE USA) and would like to discuss whether the Safety Air Guns or any point of use compressed air application in your facility can be improved, contact an Application Engineer. The truth is we all love saving a customer their resources, whether it be compressed air, electricity, liquid, or good old-fashioned cash.
