Just everything was doing great. I just filled up a cylinder. shut the air compressor down Hooked up another cylinder, carried the full cylinder out to my truck, got a glass of water went back into the shop big hum coming from the compressor motor stalled I guess I don't know whether it's the electric motor which I don't think so I think the compressor locked up or something I wasn't there to hear it. I'll have to call pyramid Monday and see about sending it back. everything was pretty well perfect until this happened. Good thing i keep 10 or mire cyls @ all times! Any one else have similar problem?
 
I have the cheaper chinese Jufeng compressor which is basically the same as the AV without some features. Mine recently had the same problem and I got it running again but it would not go above 2000psi I took the HP cylinder apart and the rings were completely shot. Replaced the rings and went right back up to 4500psi. after 5 minutes of filling a tank same thing happened. So I disassembled it again and found the rings blew again(at this point im out of rings) so I contact the company i bought it from and they are sending a new set of rings and a high pressure piston shaft. Crossing my fingers im not at a loss. I hope you figure everything out with your compressor I just figured I would share my experience with essentially the same compressor.

Ignorantly, i didnt initiate a log. I know @minimum i have 50 fills, ranging from 1000psi to4500 psi ( full). Most from 2800 to 4500. Probably 25 hrs. Oils been changed, etc.
start cooling system run foir a minute prox, start compressor. Build pressure to exceed bottle pressure then open bottle valve. Oops, I drain the vent once before starting fill and at least once during fill.

Thiis seems as if the connection between motor and compressor has failed... wish i hadn't stepped out so i could hear failure. No knocking or screaming. Everything was working normally and when i came back in shop and heard compressor not running, motot runs, compressor not turning. Still holding pressure,

Glad to hear they are making good on the compressor. I purchased one about 3 weeks ago. I used Royal Purple compressor oil and Royal Ice mixture for the coolant. Rarely gets above 50c. I only have an hour on mine. Keeping fingers crossed. Did you put ant additional filters on yours?
