Airbrush Compressor

[Rybcon]

Okay, I have an "old" compressor (Speedy Sprayer). There's a plastic plug on the side that you can pop out with your fingernail. Does this mean it probably takes oil? What kind? How much? The compressor runs fine - noisy - but I don't want to damage it. BTW, I'm not totally senile (yet). The compressor belonged to someone else.

Thanks.

Pix? I personally can't help without seeing the compressor. I had a compressor that had a "plug" on the side like that, but it was a safety valve that would pop at 25lbs pressure. Never knew what brand the compressor was, as it had stayed in the bottom of a cabin crusier on the Gulf. When I got it, believe it or not, the compressor end of the motor was caked with barnacles, and the motor end was caked in rust. Meaning it had been submerged in salt water for a time. I cleaned the barnacles and rust off of it, and sprayed it down with WD-40. I then put a new electrical cord on it, and then used that thing until I got a Badger compressor 3 yrs later. The compressor is still being used by a friend I gave it to 30yrs ago.

Without any paperwork for it then it is a guess as to whether it is an oil less or oiled unit. Some digging and research might provide an answer. If it turns out to be an oiled type you can buy air compressor oil in 8oz and 16 oz bottles at places like Home Depot and Lowes in their tool departments right near the air compressors.

With nothing to go on you might remove the plastic plug and see what drains out, if anything. WARNING - bleed off the unit of all air pressure before doing any mechanical work on any compressor!!!!
