Universal Refrigerant Compatibility

The VEVOR VP145 kit pairs a 4.5 CFM single-stage rotary vane pump with a manifold gauge set rated for R134a, R12, R22, R502, R410A, R404 and R407C. It targets automotive A/C service, residential HVAC maintenance and light commercial refrigeration work where deep vacuum is required. The package includes color-coded hoses, quick couplers, adapters, a leak detector and a storage bag for field use.

Pre-Installation Checks

Verify that the 1/4" SAE intake fitting matches the service ports on the systems you service and confirm whether the included R410A adapter and R134a quick couplers cover your typical connections. Ensure a 150 W power supply is available at the job site and that you have the correct refrigerant on hand, as the pump does not supply or recycle refrigerant itself.

Sustained Operation Behavior

The 4-stage pure copper motor drives the pump to an ultimate vacuum of 5 Pa while the 0.27 qt (260 ml) oil reservoir lubricates the vanes during extended evacuation cycles. The PRO manifold gauge maintains ±1.6% accuracy throughout the job, and the large viewing glass lets you monitor flow continuously without interrupting the process.

Questions about this item

What comes in the box and do I need to buy oil or refrigerant separately?

The kit includes the VP145 pump, manifold gauge set, three colour-coded hoses, R410A adapter, R134a quick couplers, two R134a can taps, leak detector, 1/4" SAE to 1/2" ACME adapter, storage bag, 330 ml oil bottle and user manual. The supplied oil fills the 0.27 qt reservoir; refrigerant is not included.

Should I choose a different capacity pump or is the 4.5 CFM model right for residential HVAC and automotive A/C?

The 4.5 CFM single-stage rotary vane pump with 150 W motor and 5 Pa ultimate vacuum suits residential HVAC, automotive A/C and light refrigeration work. Larger systems needing faster evacuation would require a higher CFM unit.

What does the 5 Pa ultimate vacuum mean when I am evacuating an R410A system?

A 5 Pa ultimate vacuum indicates the pump can pull a deep enough vacuum to remove moisture and non-condensables from an R410A system, meeting typical HVAC evacuation standards when used with the included manifold gauge set.
