cleaning flow lines through plasma machine

[mustangbill]

I have a cutmaster that was cutting great yesterday
today its all of a sudden telling me it has a low air flow condition
looks like I may have got carry over from my crappy air compressor and gotten
some oily crud into the unit,

is there anything I can flush through my machine that might clean it up or do I have to
replace the valve pressure switch assembly

thanks for your advice

There is a flush use on auto AC units when things go bad to clean the lines out you may check in to that stuff.

Mine used to do that when the small filter inside the case would become wet with moisture. Had to replace the small filter insert.
Finally went to a toilet paper type filter to catch the crud and moisture. You could try switch to just air flush on the rotary switch.
