VEVOR 3/4 HP HVAC Vacuum Pump 7 CFM Rotary Vane

Description

Product Overview

The VEVOR 3/4 HP two‑stage rotary vane vacuum pump is engineered for high‑performance HVAC and automotive A/C applications. Featuring a powerful 3/4 HP motor, it achieves a flow rate of 7 CFM and an ultimate vacuum of 0.3 Pa, ensuring thorough evacuation of moisture and non‑condensable gases. Constructed with a cast‑iron main body and a die‑cast aluminum housing, the pump offers exceptional durability while the built‑in cooling fan prevents overheating during extended use. The unit includes 1/4‑inch SAE, 1/2‑inch ACME, and 3/8‑inch SAE inlet ports for versatile connections, and comes with a 0.26 qt (250 ml) bottle of vacuum oil and a transparent oil window for easy monitoring.

Usage

Designed for professional HVAC technicians and skilled DIY enthusiasts, this vacuum pump excels in evacuating automotive air‑conditioning systems, servicing residential and commercial refrigeration units, and performing resin degassing or wood stabilization projects. Its compact dimensions (12.8 x 4.92 x 8.86 in) and 20.9 lb weight make it portable enough for field service while still delivering laboratory‑grade performance. Whether you are recharging R134a, R22, R410a, R1234yf, or R32 refrigerants, the pump’s multi‑port inlet configuration simplifies hookup to a wide range of gauges and service kits.

FAQ

What refrigerants can this pump handle?

The pump is suitable for small‑capacity systems using R134a, R22, R410a, R1234yf, and R32, making it ideal for most automotive and residential A/C units.

How often should I change the vacuum oil?

For typical service cycles, replace the oil after 50‑100 hours of operation or if the oil appears discolored. Regular checks via the transparent window help maintain optimal performance.

Can the pump run continuously?

Yes, the built‑in cooling fan and robust motor design allow extended use, but it is recommended to allow a brief cool‑down period after more than 2 hours of continuous operation.

Is the pump suitable for resin degassing?

Absolutely. Its deep vacuum capability efficiently removes air bubbles from epoxy and polyester resins, improving finish quality in woodworking and composite projects.

What is included in the package?

The package contains the vacuum pump, a 0.26 qt bottle of vacuum oil, a user manual, and a set of standard hose adapters for quick connection to most service kits.
