I bought the Harbor Freight 1/8 hp Airbrush compressor a couple weeks ago after I met a lady at a convention who owned one and loved it. Well, needless to say I am a little ticked because I am on my 2nd one after exchanging the first one and I cannot figure out what is going wrong. I have used all the correct attachments, teflon tape for the seals and these are my 2 main issues.
1) It is losing air SOMEWHERE because about every minute it turns on for a second and then shuts off. This was happening with the first compressor so I took it back.
2) No matter how high I set the regulator, if I hold open the airbrush trigger for more than a few seconds, it drops to 20 psi and never goes any higher, no matter what I do to the gauge. (this is a new problem unique to this compressor. Didn't have the problem with the other one) As soon as I let go, the gauge goes back up to 30, 40, 50 whatever I set it at, but no matter what, I can't spray any higher than 20psi.
PLEASE if anyone can lend me some advice, I would greatly appreciate it. Please refrain brand bashing if you happen to not be a fan of Harbor Freight! But at this point I think I will have to go with something a bit more higher end!
