Product description

The Mastercool 90066-220-BLSF is a powerful, high capacity spark free vacuum pump , specifically designed for working with both traditional and flammable refrigerants. The pump combines high vacuum performance with improved internal oil flow and precision machining, resulting in lower operating temperatures, reduced wear and longer service life.

The thermally protected motor, together with the gas ballast valve and check valve, ensures stable and safe operation even under demanding conditions. The manifold valve allows the pump to be isolated from the system during leak testing.
