VEVOR Vacuum Pump, 113 L/min(4 CFM), HVAC Single Stage Rotary Vane Vacuum Pump, for R134a R22 R410a Systems, Auto AC Vacuum Pump Kit with Oil Bottle, for Automotive Air Conditioner Maintenance Resin Degassing

Single Stage Rotary Vane Vacuum Pump with 150W Pure Copper Motor Powers

A sturdy 150W pure-copper motor, designed for consistent, long-term performance under heavy use, is the foundation of our VEVOR single stage rotary vane vacuum pump. It rapidly removes air, moisture, and non-condensable gases from refrigerant lines with a free air displacement of 4 CFM (113 L/min), reducing evacuation time on every job. Even during consecutive evacuation cycles, the motor's output remains steady and consistent due to the pure copper winding's superior resistance to heat accumulation compared to aluminum substitutes.

This combination of speed, power, and durability directly benefits technicians who service residential HVAC equipment or automobile air conditioning systems. Faster evacuation cycles let technicians finish more jobs in a single shift and reduce downtime waiting on the pump. This pump's motor delivers the power to handle substantial refrigerant work without hesitation, whether you're a professional HVAC contractor or a do-it-yourself enthusiast tackling a home project.

5 Pa Ultimate Vacuum for Deep HVAC System Evacuation

This pump eliminates moisture, trapped air, and non-condensable gases significantly more thoroughly than less powerful models on the market, reaching a final pressure of 5 Pa. Before recharging any R134a, R22, or R410A system, a thorough evacuation is necessary, as any remaining moisture can damage internal components and reduce cooling performance. This degree of vacuum performance helps technicians verify that a system is ready for refrigerant charging.

Thoroughly evacuating the lines protects compressors, valves, and other sensitive components from extended damage caused by lingering impurities. Systems serviced with this pump are cleaned to a level that ensures dependable, long-term cooling performance so that technicians can rest easy. Whether you're managing a fleet of service vans or just one home air conditioner, that degree of assurance is important.

Dual 3/8" and 1/4" SAE Ports for Broad Refrigerant Compatibility

Equipped with both 3/8" and 1/4" SAE intake ports, this single stage rotary vane vacuum pump attaches directly to numerous manifold gauge sets and hoses, eliminating the need for extra adapters. Because of its inherent adaptability, it can be used with both smaller-tonnage household HVAC equipment and automobile air conditioning systems. It covers the majority of tasks a technician encounters and is suitable with R134a, R22, R410A, and other non-flammable refrigerants.

One device with two port sizes eliminates the need for personnel to carry several pumps or search for adapters while working on a project. The dual-port design maintains your workflow's efficiency and continuity, whether you're transferring between a car air conditioner and a residential system during the same service call. This vacuum pump is a sensible option for stores handling a variety of service requests, thanks to its broad compatibility.

260 ml Oil Capacity with Visible Window for Easy Level Checks

Monitoring lubricant levels requires only a glance, not speculation, thanks to its 0.27 qt capacity. (260 ml) Oil capacity and an easily visible oil window. In addition to keeping internal parts lubricated, proper oil levels shield the pump from premature wear during lengthy or frequent evacuation cycles. The pump comes with a 0.35 qt. (330 ml) bottle of vacuum pump oil, so you can get to work straight away.

Instead of becoming a guessing game at the conclusion of a work, routine oil checks become part of a basic maintenance practice. To help the pump maintain steady suction and a stable ultimate vacuum during repeated applications, technicians can top up the oil before it runs low. This simple, low-maintenance design keeps the device ready for the next repair appointment and minimizes downtime.

Built-In Cooling Fan for Stable, Overheat-Free Operation

Even when the pump operates continuously for extended periods, a built-in cooling fan works in tandem with the pure copper motor to actively dissipate heat. This design helps prevent overheating, which often shortens the lifespan of inferior hoover pumps commonly used in busy stores. Internal operating temperatures remain well within a safe, manageable range even during lengthy, consecutive evacuation jobs, ensuring reliable performance throughout the entire process.

More consistent vacuum levels throughout each task, not just in the initial minutes of operation, result from stable thermal performance. Without worrying about heat shutdowns or a gradual decline in performance, technicians managing multiple systems during a single shift can rely on consistent, predictable output. Over months of consistent, rigorous use in the field, that kind of dependable cooling adds up.

Versatile Single Stage Rotary Vane Vacuum Pump for HVAC, Auto AC, and Resin Degassing

This single stage rotary vane vacuum pump is handy outside of typical HVAC work because it can handle tasks such as wood stabilization and resin degassing, in addition to standard refrigerant servicing. It is easy to move between job sites or fit in a service truck thanks to its compact size (10.83 x 4.72 x 8.86 inches) and net weight of 11.46 pounds. For professionals who travel to several places during the day, portability is crucial.

This pump adapts without requiring any specialized equipment, whether for a workshop resin project, residential HVAC service, or vehicle AC maintenance. It is a useful addition to any technician's toolkit or do-it-yourself workshop because of its wide refrigerant compatibility and consistent hoover performance. This single stage rotary vane vacuum pump provides dependable equipment that meets the needs of shops and individuals performing a variety of tasks.
