HVAC Vacuum Pump for Refrigerant Systems

The VEVOR VP125 is a single-stage rotary vane vacuum pump rated at 3.5 CFM free air displacement with a 1/4 HP motor. It is built for technicians who service automotive air conditioning and low-tonnage residential HVAC units using R134a, R22 or R410a refrigerants. The pump reaches an ultimate vacuum of 5 Pa and runs at 1720 RPM for thorough evacuation.

Included Oil Bottle and Dual Port Fittings

A 330 ml oil bottle ships with the unit so the 260 ml reservoir can be filled before first use. The visible oil window lets operators confirm the level without tools. Intake fittings comprise a 1/2" ACME and a 1/4" SAE port, allowing direct connection to common automotive and residential service hoses without extra adapters.

5 Pa Ultimate Vacuum Determines Evacuation Depth

The 5 Pa ultimate vacuum specification defines how deeply the pump can pull down a system before refrigerant charging. If the service procedure or equipment standard requires a lower micron level, this pump will not meet that threshold. For standard R134a, R22 and R410a evacuation tasks the 5 Pa rating is the deciding figure.

Questions about this item

How often should the vacuum pump oil be changed and what volume does it take?

The pump holds 260 ml of oil; change it when the oil looks cloudy or after every major evacuation job to keep the 5 Pa ultimate vacuum.

What limits continuous running time on this rotary vane pump?

The built-in cooling fan and 4-pole motor are designed for extended use, so the practical limit is the 260 ml oil capacity before a top-up is needed.

How loud and hot does the VP125 get during all-day HVAC work?

The 1/4 HP motor runs at 1720 RPM with a cooling fan; expect moderate workshop noise and warm casing temperature during sustained operation.
