This is a 2 stage oilless 7HP, 175 psi made in the USA professional air compressor. Recently started to take longer to pressure up. I have new heads for it and compression rings too. I recently purchased a smaller portable compressor that is more suited for my needs. If you have any questions please call or text

***UPDATE*** Found bad compression ring, replaced it and now it pressures normally.
