What is a vacuum pump?
A vacuum pump removes air and gas from a sealed space to lower its pressure. In refrigeration and air conditioning, it evacuates air and moisture before charging refrigerant.
Two-stage pumps reach a deeper vacuum than single-stage pumps, and more stages go deeper still. Oil-sealed rotary vane pumps are the common type for service work.
