The DIVERSITECH VACOIL is a one-quart container of vacuum pump oil formulated specifically for HVAC vacuum pump operation. The oil provides internal lubrication and sealing within the pump during system evacuation procedures, helping maintain pump efficiency and consistent draw-down performance. It is the type of consumable product that licensed HVAC technicians keep on hand during refrigerant system service, installation, and commissioning work where deep vacuum is required before charging.
The VACOIL is suited for use in residential and light commercial HVAC service scenarios where vacuum pumps are used to evacuate refrigerant circuits prior to charging. Regular oil changes are a standard part of vacuum pump maintenance, and using a purpose-formulated oil helps preserve pump internals and sealing performance over time. It is appropriate for use during new system installation as well as retrofit and changeout work.
Designed as a purpose-formulated vacuum pump oil for use in HVAC vacuum pumps during refrigerant system evacuation and service procedures.
Vacuum pump oil service is typically performed by licensed HVAC technicians following the pump manufacturer's recommended change interval or whenever the oil appears discolored or contaminated with moisture. Before changing the oil, power down the vacuum pump completely. Dispose of used vacuum pump oil in accordance with local regulations, as it may contain refrigerant residue and contaminants drawn from the refrigerant circuit.
