| Air compressor air problem Have a 30 gallon air compressor. Will build up to 120 pounds with no problem. Coming out of the tank it will shut high pressure for two to three seconds and then drop to hardly no pressor. The pressure will not run a HVLP spray gun which it did at one time. Have drain tank. Air compressor is around 1 year old from harbor freight. Hope someone can help or I will have to buy another Thanks Derick |
