Thank you sir!!!!! I will assume the air you are blowing is clean and dry and not straight from the compressor...?
That is correct.
Clean dry air at the point where everything happens is critical. If you’re pushing contaminants downstream from your compressor, they’ll end up in your work no matter how clean you have the panel to begin with.
I have redundancy built in to the compressed air system in my garage, there’s a regulator, a particulate, and coalescing filters mounted immediately as it comes out of the compressor. Then it goes through a refrigerated dryer, then through a second desiccant dryer at the opposite end of the shop. Just to make absolutely sure the air is clean and dry by the time it hits the hose.
Of course, it does help that I happen to be a compressed air service technician, and that it’s my business to know and build these systems.
