Oil-less piston. Like I said, it's a known issue with these little compressors, but having said that there are no reported failures because of it (probably because they're rarely used continuously, it's not as if they're spraying a car). The heat comes from the motor, not so much from the piston/cylinder head. I toyed with the idea of completely stripping it to drill out more holes for better circulation but couldn't be bothered as it will work fine like it is. Another possibility is to fit a small air tank to it, like my other one - maybe one day? I'm still annoyed that I can't fit the pistol-grip airbrush to the cordless compressor.

The heat comes from compressing the air; the motor heat is insignificant by comparison. Quote

There are about 6 or 8 different airbrush to hose fittings. I suggest you contact this model shop. He may be able to fix you up with the correct fittings or adapter.

Ordinarily I would agree, but in this case the piston assembly is shielded from the motor by a "bulkhead", for want of a better term, and while the head gets hot it's nowhere near as hot as the area of the casing that's above the motor coils. I've taken temperature readings to try and localise the main source of the heat. The fan on top keeps the cylinder head noticeably cooler, the motor only slightly so. It's just poor design of the motor housing. Fred, thanks for that, lots of interesting stuff to look through there!
