The Soft Grip Safety Air Gun for OSHA Compliance

Compressed air has many different uses ranging from simple cooling and blow off applications all the way to operating machine cylinders and robotics. One of the most common uses is for simple cleaning; whether its cleaning off a work station or blowing off personnel it can’t be denied that air powered cleaning is very useful. But if the Occupational Safety & Health Administration (OSHA) regulations are not followed it can also be unsafe.

Open-ended blow offs can inadvertently be dead ended (the airflow outlet can be completely blocked), when this happens if the pressure is to high an air embolism can form in an individuals bloodstream. Blowing something off with air can result in airborne particulate traveling at a high velocity that can become embedded into your skin or in your eye.

With all that being said this is where the safety air guns step into the spotlight! It’s pretty easy to make a safety air gun that complies with the dead-end pressure regulation; just give the air another path to take when the outlet is blocked. The most common solution found is a cross drilled nozzle which allows the air to escape when the end is blocked. Generally the problem with this design is that the nozzles can be very loud and inefficient. In most cases these nozzles have paid attention to the dead end problem but ignored the noise level exposure safety issue and completely ignored compressed air efficiency. 

With EXAIR’s Super Air Nozzles you get both the added benefit of being safe, quiet and efficient. Our engineered designed air nozzles are commonly installed onto a Soft Grip Safety Air Gun to make an ergonomic, safe, and quiet Safety Air Gun. These can also have a  Chip Shield added to help prevent particles from flying back and hitting the user. The Soft Grip Safety Air Gun can also be coupled with a pipe extension from 6” to 72”; you can also add one of our Stay Set Hoses 6” in length to 36”.

Super Air Knife Provides Engine Block Blowoff

Extra points if you can identify this engine block

My hobby with cars is no secret.  Most people who meet me come to know I’m a total gearhead.  Case in point, on a recent trip to visit with our distributor in Finland, I was asked about the car I was working on when they last visited us just a few months ago.  Since then, the aforementioned car (a blue BMW) has found a new home, and I’m gearing up to sell another.

So, when I received an email from a major auto manufacturer needing a solution to clean the top side of an engine block, I was intrigued.  In addition to the photo above, I received the photo below with a short description of the current state in the application.

The top deck of this block, where the cylinder head gasket will rest, has a width of approximately 200mm.

As it stands, coolant is accumulating on the top side of the engine block after they are fully cast, decked, and cleaned.  In order to move on to the next step in the process, these engine blocks need to have all residual oil removed from the top side of the block.

The solution?  A 9” (229mm) Super Air Knife installed above the engine blocks as they travel down the production line.  The Super Air Knife will install at a 45° angle of attack, blowing off the residual coolant and allowing these parts to move on in the process without stopping.  This prevents lost throughput due to stoppage of the production line, prevents increased costs due to personnel needing to treat each engine block by hand, and provides a uniform condition for the engine blocks when they arrive in the next step of this production process.

The best part of the interaction was that this auto manufacturer contacted EXAIR for a solution because they were able to solve previous problems with overheating electrical control panels using our Cabinet Coolers.  So, when they needed another compressed air solution, they immediately knew who to call.

If you have an application in need of a compressed air solution, give us a call.  We’ll be happy to help.
