Air  compressor unit. Essick Md f325.  


At inatial start up compressor sucks in air. After a few seconds air is pumped out of the intake. There is some pressure in the tank but not much. The unloader valves are operated by oil pressure. oil pressure set at 25 psi.

Is this a small piston type compressor? It sounds like the valves in the cylinder head are broken.

Best,

Cas
