Is This What Your Blowing ‘implement’ Looks Like? If So, We Can Help……

Does your homemade blow-off “lance” look like something from a 15th century dungeon?

No consideration for excessive noise levels for the operators in the area. No consideration for basic safety regarding dead-end pressure levels that can be achieved with an implement like the one pictured above. Not to mention the fact that the operator has to lean over this moving material in order to hit his target that is 3 meters away! Yikes! Hugely inefficient use of not only compressed air but operator time and company resources! “But this is the way we have always done it.”, replies the person on the other end of the conversation. Not if OSHA has anything to say about it.

Take a look at this application in a plant that produces engine blocks. All of the ‘blow-offs’ are smashed pipes and tubes connected to an un-filtered, un-regulated compressed air supply.

The customer was complaining because when the application was activated to blow off the target motor block, the resulting sound level was 100 dB +. Also, they had a very difficult time with the compressor system being able to keep up with what amounts to the equivalent of 15 open ended 1/2″ tubes just blowing compressed air at the block. Some care was taken to actually hit various features of the target, but in no way does the application begin to define the concept of efficient use of compressed air.

Scenes like the ones pictured above are exactly the kind of situations for which EXAIR has loads of good advice and a huge selection of engineered solutions that we can pick from in helping the customer reduce noise, save compressed air and make the application compliant with safety standards for industry (OSHA). Sometimes, it takes stepping back from the problem, getting a fresh set of eyes on the problem to come up with some pretty cool solutions. Those solutions can be as easy as simply screwing one of our engineered nozzles onto the end of a threaded pipe to reduce noise and air consumption. Or perhaps the solution involves the simple use of strategically placed nozzles controlled by a filtered, regulated, automatic air supply that only comes on when a target is present and ready to be blown off.

I know we keep saying it in just about every blog post, but it is true. If you have situations that are similar to the ones above, give us a chance to help you make your application safer, quieter and more efficient in compressed air use. Who wouldn’t want to spend less money on compressed air?
