Using a twin piston (oiled) belt drive 3HP compressor, what sort of filtering would you use for co-axial air assist to protect the lens? Planning to run 30 PSI approx as this in earlier testing gave superb results on wood cutting with minimal clean up or masking required, preventing charring of very fine cutout work.
Supplied with the compressor is a green floor standing cylinder which is full of a fibrous material which has some rust stains and leaks a bit. The cylinder is quite rusty from just using once or twice, so we weren't going to bother.
Next is a blue possibly alloy (rust free inside) "compressed air fine filter" which has an approx 10" long cylindrical filter. Planning to use this.
Finally a regulator with water trap and mesh filter, then into the machine where I've installed a solenoid whose control is working well.
Awaiting a few bits of pipe to hook it all up, but wondering if water and oil from the compressor will clog the "fine" filter and whether some sort of coarse filter should be used too?
