Paskals TestPAC is a self-contained, compressed air-powered device that can generate liquid pressures up to 100,000 PSI for on-site high pressure testing. It uses a reliable Haskel pump known for its long life and low maintenance. The TestPAC operates by using a plant air supply of at least 8 bars to boost an inlet liquid to pressures as high as 100,000 PSI through a reciprocating piston system, with automated controls for ease of operation.
