A HVAC vacuum pump is a pump used to discharge air and small quantity of vapour from a refrigeration system such as residential and automotive air conditioning. Besides its popular name of HVAC vacuum pump, people also call it refrigeration vacuum pump, refrigerant vacuum pump, air conditioning vacuum pump, auto ac vacuum pump and many more. It is basically an oil-sealed rotary vane pump which has a robust structure and good stability.
Throughout the servicing procedure in a refrigeration system and because of leaks, it is very common that other contaminants mix with oil and refrigerant, which are two basic components of a refrigeration system. The contaminants encompass gases like oxygen and nitrogen, as well as water vapour.
It is essential to remove such contaminants from the system by using a HVAC vacuum pump. The potential consequences include negative impact on efficiency of the refrigeration system and damage to other components of the system, etc.
Besides it’s main application in refrigeration system, the HVAC vacuum pump can be used also in vacuum packaging machines, light duty vacuum coating, vacuum lifting, etc.
