Automotive AC Vacuum Pump with 7 CFM Two Stage Performance

This automotive AC vacuum pump operates as a two-stage rotary vane pump. It draws 7 CFM (198 L/min) of free air displacement through a 3/4 HP, 550W motor. That two-stage design is especially important for A/C work because a single-stage pump usually cannot create a vacuum deep enough or fast enough to completely remove moisture and air from a sealed automotive system before charging it with refrigerant.

The higher flow rate also means shorter evacuation times per job, which is especially important when servicing multiple vehicles in a day versus just one system at home. A 7 CFM two-stage pump shortens the wait time between hooking up the gauges and being ready to recharge for technicians or DIY users who regularly work on car A/C systems. That speed and the correct depth of vacuum are what distinguish a pump designed for automotive work from a basic shop-grade unit.

0.3 Pa Ultimate Vacuum for Deep, Thorough System Cleaning

The final vacuum on this pump is 0.3Pa / 2.25 microns. This depth is low enough to extract trapped moisture and air that a shallower vacuum would leave behind in the A/C system. It is directly related to A/C performance, as residual moisture in a refrigerant line can freeze, corrode components, or reduce cooling efficiency over time.

This level of vacuum also confirms that the system is properly sealed before recharging, because a pump that cannot hold a deep vacuum usually indicates a leak somewhere in the lines or fittings. For auto techs, this is not an option; it is the difference between a repair that works and one that fails in a few weeks. A rating of 0.3 Pa provides sufficient margin to fully remove moisture from systems left open or exposed to humid air before service.

4 Pole Motor and Cast-Iron Housing for Stable Long Runs

It has a 4-pole, high-torque motor that allows this pump to run continuously through longer evacuation cycles without losing power partway through the job. That consistency is most critical when a vehicle’s A/C system requires an extended pull-down. A motor that fades under prolonged load can leave a job half-finished or undersized on vacuum depth.

The housing itself is cast iron and die-cast aluminum, both selected for their ability to handle vibration and heat without warping or cracking after repeated use. With this housing comes a built-in cooling fan to help manage heat buildup during back-to-back jobs, which is common in shop environments that service multiple vehicles in a single day. The motor torque and cooling design work together to ensure stable performance during the repeated, extended use that automotive work demands from this pump.

Three Air Inlet Ports for Wide Refrigerant System Compatibility

This automotive AC vacuum pump has 1/4" SAE, 1/2" ACME, and 3/8" SAE air inlet ports, covering the sizes most common to automotive and small refrigeration installations, so you won't have to find separate adapters for each job. That versatility is important when you're working on different vehicle makes or system types in the same service session.

R134a, R22, R410A, R1234YF, and R32 refrigerants are compatible with both newer refrigerant types used in modern cars and older systems still in use. Having a single pump that connects to all of these port sizes and refrigerant types eliminates the need for shops or technicians working on a mix of older and modern A/C systems to switch equipment between jobs. Because of this adaptability, there are no workflow gaps caused by mismatched fittings.

250ml Oil Capacity with Transparent Window for Easy Monitoring

The pump is filled with 0.26 qt (250 ml) of vacuum oil and has a clear oil window built into the housing, allowing you to check the fluid level at a glance without a teardown. Oil condition has a greater impact on vacuum pump performance than most users realize, as contaminated oil or low oil levels directly affect how deep a pump can pull a vacuum.

The unit includes a bottle of vacuum oil, so it is ready to operate right out of the box without any additional purchase before the first job. The ability to see the oil level and clarity at a glance makes it easier to spot when the oil needs changing, especially after pulling a vacuum on a system with high moisture or contamination. That visibility means routine maintenance becomes a quick check, not a guessing game.

Automotive AC Vacuum Pump Built for HVAC and Refrigeration Tasks

This pump is primarily intended for car A/C operations, but it can readily be expanded to larger HVAC repair, refrigerator servicing, resin degassing, and even wood stability. That breadth is built on the same principles: broad refrigerant compatibility and dependable deep vacuum that works with a variety of equipment types, not only cars.

That vacuum depth makes this unit effective on car A/C systems, but home users who take on resin or woodworking projects benefit as well. This automotive AC vacuum pump is built to handle the vacuum demands of a vehicle recharge or a small refrigeration repair without requiring task-specific equipment for every job. For shops that do both automotive and general HVAC work, one pump that covers both needs reduces redundant equipment on the bench.
