Well thanks to Hobby Lobby's 40% off coupon and a customer visit two hours south of here (closest Hobby Lobby), I went and got me one of them double action thingies..err airbrushes. Iwata HP-CS, neat little HL bundle with some AB cleaner, three totally useless ComArt paint bottles (well, after I dump out the paint and use 'em for Windex, etc they'll be useful) and this topic's subject: the Iwata Pistol-Grip Filter. I understand the use, 5micron moisture/dirt trap. I'm using a tankless compressor, so I don't know if I even need to use it. After hooking it up inline with the CS and the compressor, I noticed a significant LACK of air pressure coming from the compressor, like under 5PSI when I have it set for 20PSI. There is quite a bit of air escaping from the filter "purge" fitting. I see it has a screw, is this adjustable? I'm assuming it's shipped in the full open position, but there are no notches in the head to use a micro screwdriver. Am I just pulling a blonde moment here?
Here's a crude shot of what I'm talking about:
Thanks in advance.
