Well, my compressor is NFG. After going through all set-up and zero pressure break-in, won't achieve more than ~250psi. Yes,
psi. Initiated contact with eBay seller and waiting to see what they will say.
This is not a product for someone who just wants to add oil & coolant, plug in and fill guns. Mine had several issues from the start.
While I did not think about it at first, the little LCD temperature indicator should have been on at all times, not just when the compressor was powered up. It runs on batteries. So for the 12 minutes of zero pressure break-in, I just used a handheld infrared thermometer to monitor temperature, which never got above 54C. Not surprising - it had no load on it.
When I first turned on the cooling system, the main fan did not run. I thought that maybe it would only come on at a certain temperature, but then I moved the blade with my finger and it started to turn slowly and loudly. Ultimately I had to use a wooden rod to 'adjust' the fan's position in its housing, after which it ran faster, started up every time and ran much quieter.
Run timer was placed using double sided tape on the base of the compressor, where it would vibration activate when the compressor motor was running, but not when the cooling system alone was running.
All points of air tube connections were checked with CRC aerosol leak detector, but no leaks were found. Just not building pressure.
After about 15 minutes of running the cooling pump sounds like a can of rocks. I think that it might be magnetic drive. Maybe some contaminant was in the cooling system and is in the impeller region of the pump now? Still seems to be moving fluid, just really loud now.
Bummer...
