VEVOR AC Vacuum Pump and Gauge Set, 7 CFM 198 L/min, Two Stage Rotary Vane HVAC Vacuum Pump, A/C Manifold Gauge Kit, for R134a R22 R410a, with Leak Detector Carry Bag, for Auto HVAC Air Conditioning

Two Stage Rotary Vane Vacuum Pump Reaches 0.3 Pa Ultimate Vacuum

This two stage rotary vane vacuum pump pulls down to an ultimate vacuum of 0.3 Pa / 2.25 microns, a depth that single-stage pumps in this same product family cannot reach. That second stage is a bigger deal for A/C work because it removes trapped moisture and air more thoroughly than a single-stage design does, reducing the chance of leftover moisture freezing or corroding parts after a recharge.

For technicians or serious DIY users working on multiple vehicles or larger refrigeration systems, this deeper vacuum also more reliably confirms that the system is sealed before charging begins. If you can't reach that depth with a pump, it's often a sign of a leak somewhere in the lines, so being able to hit 0.3 Pa consistently gives confidence that the evacuation step actually worked. This is the best vacuum performance across the family's kit range.

7 CFM Output from a 3/4 HP, 4-Pole High-Torque Motor

The two stage rotary vane vacuum pump has a 3/4 HP, 550W motor at 7 CFM / 198 L/min, the most powerful in the kit lineup, and is intended for faster evacuation on larger systems or multiple jobs in a day. The higher CFM also reduces wait time between hooking up gauges and being ready to charge, which is important for shops or technicians who service more than one vehicle in a session.

The 4-pole high-torque design keeps this output up during longer evacuation cycles and doesn’t taper off under sustained load. This motor, combined with the deeper two-stage vacuum, provides the pump with the power to handle quick-turnaround jobs and more demanding systems that require longer pull-down times. It’s the most powerful motor in this kit family.

Manifold Gauge Set Offers ±1.6% Pressure Reading Accuracy

The included manifold gauge set provides ±1.6% measurement accuracy, the precise standard across this kit family, providing readings that are reliable enough to charge a system correctly without guessing. That precision is just as important on a big, two-stage pump as it is on a smaller single-stage one. No matter how strong the vacuum pump itself is, incorrect charging can harm components.

Dual-unit display means you don’t need a separate conversion chart to read the gauge in different units, and a clear oil window adds another quick visual reference. The gauge housing's high-pressure resistance remains unchanged after repeated connect/disconnect cycles across multiple service jobs. The gauge set, along with the more powerful pump in this kit, ensures that greater vacuum performance translates into a properly charged system, not just a deeper pull.

Three-Color Hose Rated for 800 to 4000 PSI Working Pressure

A 3.94 ft / 1.2 m three-color hose set is included in red, blue, and yellow to easily identify the high side, low side, and utility connections during service. That color coding reduces the chance of cross-connected lines, which is important on faster-paced jobs where this higher-output pump is likely to be used more often.

The working pressure of these hoses is 800 to 4000 PSI, which provides sufficient margin for higher-pressure refrigerant systems without a high risk of hose failure during evacuation or recharge. Secure fittings at each connection point help to maintain a sealed line throughout the entire service process. These hoses are intended for tougher, more frequent use and match the deeper vacuum capability of the stronger pump in this kit.

Built-In Leak Detector for Faster System Diagnosis

This kit includes a leak detector, which is not available in the lighter single-stage kits in this same product line, providing a diagnostic step before even beginning evacuation. Finding a leak early means you don't waste time pulling a vacuum on a system that won't hold it, which is especially important on tight jobs.

A leak detector with a gauge set and a two-stage pump provides a more complete diagnostic and service workflow in one kit, convenient for technicians who need to verify that a system is sealed before committing to a full recharge. If you do more involved A/C work, this addition means that troubleshooting is part of the kit itself, rather than a separate tool to source. This is one of the biggest upgrades that sets this kit apart from the smaller kits in the same family.

Two Stage Rotary Vane Vacuum Pump Kit Includes Full Carry Bag

This two stage rotary vane vacuum pump kit includes the pump, gauge set, hoses, adapters, can taps, leak detector, and a 0.26 qt / 250 ml bottle of oil, all fitting into an included carrying bag, so the whole higher-capacity setup is organized and ready to go. This organization is more significant here than in the smaller kits because this set has more individual pieces.

Pre-packaged for mobile technicians or shops working this pump at several job sites, it saves setup time and reduces the risk of losing small parts such as adapters or the leak detector. It’s the most capable kit in this family, yet it still travels in a single grab-and-go case. The carry bag ensures that the added performance and extra tooling don’t add extra hassle.
