VEVOR Vacuum Pump for HVAC — 7 CFM 3/4 HP Two-Stage, 0.3 Pa Ultimate Vacuum, Oil Included

VEVOR’s two-stage rotary vane vacuum pump is a powerful 7 CFM, 3/4 HP unit engineered to evacuate automotive and small HVAC refrigerant systems down to an ultimate vacuum of 0.3 Pa.

This compact but robust pump combines a 4-pole high-torque motor with durable cast-iron and die-cast aluminum construction, delivering steady performance for refrigeration servicing, A/C maintenance, resin degassing, and wood stabilization projects. It arrives ready to use with 250 ml of vacuum oil and a transparent oil window for quick level checks. Multiple inlet fittings give broad compatibility with common refrigerants including R134a, R22, R410a, R1234YF and R32.

How does this vacuum pump perform during extended jobs?

The pump’s 4-pole motor and built-in cooling fan help it run steadily without overheating, making it suitable for prolonged service tasks. Its two-stage rotary vane design improves pull-down speed and ultimate vacuum compared with single-stage units.

• 3/4 HP motor provides constant torque under load
• Built-in cooling fan prevents thermal buildup
• Two-stage pumping reaches deeper vacuums faster
• Cast-iron/die-cast housing resists wear during long runs

Which refrigerants and fittings are supported for automotive A/C work?

VEVOR designed this pump to connect easily to common service ports using the included inlet adapters. It supports a wide range of modern and legacy refrigerants used in automotive and small HVAC systems.

• Compatible with R134a, R22, R410a, R1234YF and R32 systems
• Includes 1/4-inch SAE, 3/8-inch SAE, and 1/2-inch ACME inlet options
• Quick hookup to manifold gauges and service hoses
• Suitable for both automotive and residential HVAC lines

What maintenance and user-friendly features make it ready out of the box?

The unit ships with the correct amount of vacuum oil and a visible sight glass so you can verify oil level at a glance. Simple service points and straightforward controls reduce downtime and simplify routine checks.

• Includes 0.26 qt (250 ml) of vacuum oil for immediate use
• Transparent oil window for easy visual monitoring
• Oil fill and drain designed for tidy maintenance
• Durable handles and stable base for workshop use

Can this pump handle non-HVAC tasks like resin degassing or wood stabilization?

Yes — the deep vacuum capability and steady flow rate make it well suited for degassing pours, impregnating wood, and similar small-scale production tasks. Its rugged construction withstands workshop environments while delivering repeatable results.

• 7 CFM flow supports small-to-medium resin chambers
• 0.3 Pa ultimate vacuum allows effective bubble removal
• Stable motor and cooling for continuous degassing cycles
• Portable footprint fits many benchtop setups

Who this is for: The VEVOR 7 CFM two-stage vacuum pump is aimed at technicians and serious DIYers who service automotive and residential A/C systems, as well as makers and small shops needing reliable vacuum for resin work or wood stabilization. It suits users who want a ready-to-run unit with multiple inlet options, visible oil management, and the capacity to handle sustained jobs without frequent cooldowns.
