VEVOR Vacuum Pump, 100 L/min(3.5 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

VEVOR Single Stage Vacuum Pump Runs on a 4-Stage Pure-Copper Motor.

The 4-stage pure copper motor that powers this single stage vacuum pump is built to withstand demanding, repeated evacuation cycles without losing power. Internal temperatures remain constant even during lengthy tasks thanks to an integrated cooling fan that works in tandem with the motor to dissipate heat. The device offers the durability technicians require for consecutive service calls, thanks to its copper construction and active cooling.

Stable thermal performance eliminates the progressive slowdown that plagues less expensive pumps, ensuring steady suction from the outset to the final minute of operation. This unit is designed to operate at a constant level throughout the cycle, whether you run it for 10 minutes or an hour. For those who rely on this pump as a daily tool rather than a sporadic accessory, its dependability is crucial.

3.5 CFM Free Air Displacement for Fast, Efficient Evacuation

This single stage vacuum pump, rated at 3.5 CFM (100 L/min), swiftly removes air and refrigerant gas from HVAC and automobile AC lines, reducing the time spent waiting for evacuation before a recharge. Shorter job cycles result from faster displacement, allowing technicians to switch to the next car or system sooner. That speed translates into real-time savings for stores managing multiple service appointments in a single day.

This airflow rate is ideal for both automobile air conditioners and smaller-tonnage household systems, where rapid turnaround is sometimes crucial. Not having to wait too long for the lines to clear is also advantageous for do-it-yourselfers working on a single stage vacuum pump repair or a home HVAC unit. The end product is a pump that works well in both professional and informal repair processes.

5 Pa Ultimate Vacuum Ensures Thorough Moisture and Air Removal

Compared to less effective options on the market, this pump eliminates trapped moisture, air, and non-condensable gases more thoroughly by pulling down to an ultimate vacuum of 5 Pa. Before refrigerant charging, complete moisture removal is essential, as any remaining water vapor can eventually cause ice formation, corrosion, or reduced cooling efficiency. When a system reaches this level of cleanliness, technicians can be confident that they have thoroughly prepared it before sealing it back up.

Sensitive parts like expansion valves and compressors are shielded from long-term wear brought on by lingering impurities by a strong, deep vacuum. Systems that are serviced in accordance with this standard typically operate more efficiently and more coolly and require fewer callbacks for moisture-related problems in the future. Because of these factors, the 5 Pa rating is more than just a label number; it is a meaningful specification.

Dual 3/8" and 1/4" SAE Ports for Cross-System Compatibility

This pump connects directly to most conventional manifold gauge sets without additional adapters, as it has both 3/8" SAE and 1/4" SAE intake fittings. It covers most of the tasks a technician completes in a normal workweek and works with R134a, R22, R410A, and other non-flammable refrigerant systems. Because of its adaptability, a single pump can seamlessly transition between residential and automobile HVAC tasks.

A technician's toolkit is simplified, and the likelihood of getting caught without the proper adapter mid-task is reduced by carrying a single tool that adapts to various port sizes and refrigerant types. The dual-port design keeps the workflow smooth, whether you are installing a mini-split at home or recharging an automobile air conditioner. The pump's inherent adaptability makes it suitable for a variety of service routes.

260 ml Oil Capacity with Visible Window for Effortless Monitoring

Checking lubricant levels requires a glance rather than speculation or disassembly, thanks to the housing's 0.27 qt capacity. (260 ml) Oil capacity and clear oil glass. The pump's ability to maintain a deep vacuum over time is directly supported by proper oil levels, which safeguard internal seals and moving parts. The unit comes with a 0.35 qt. (330 ml) A bottle of vacuum pump oil for immediate use.

Regular oil checks help avoid the performance decline that results from running low on lubricant by becoming a quick habit rather than an afterthought. In just a few seconds, technicians may replenish the oil in between tasks, ensuring that the pump runs at maximum efficiency without unplanned downtime. This simple maintenance design contributes to the unit's dependability during months of frequent use.

Compact, Lightweight Single Stage Vacuum Pump Built for Multiple Applications

This single stage vacuum pump, measuring 10.83 x 4.72 x 8.86 inches and weighing only 11.24 pounds, is compact and convenient to transport between job sites and store in a service truck. Because it still provides the CFM and vacuum performance required for significant refrigerant operation, its small size does not come at the expense of capability. Technicians who move around a lot during the day benefit from this balance of power and portability.

This pump can be used in workshop environments for tasks such as wood stabilization and resin degassing, as well as conventional HVAC and automotive AC servicing. It adjusts without requiring additional specialized equipment, whether the task involves refrigerant evacuation or specialty degassing. This pump provides consistent, multipurpose performance in a lightweight design for both technicians and do-it-yourselfers.
