VEVOR 255 L/min(9CFM) 746W(1HP) Air Condition Refrigerant Vacuum Pump vacuum chamber with pump degassing chamber with pump ac vacuum pump

VEVOR Dual-Stage Vacuum Pump for Refrigeration System with 1HP Copper Motor

The two-stage rotating design of this vacuum pump for refrigeration system is powered by a heavy-duty copper motor rated at 1 HP and 220V/50Hz. The dual-stage system gradually draws air through while spinning at 1720 rpm, attaining a constant flow rate of 9.0 CFM (227-255 L/min) for complete moisture removal. The entire machine is encased in a durable aluminum alloy shell that resists dents, corrosion, and the normal wear and tear of continuous workshop or field use across various job sites.

The copper motor maintains continuous power without overheating, allowing technicians to evacuate larger refrigeration lines and AC systems in a single pass. This means less downtime for cooling and more efficient operation. Stable torque, dual stage suction, and consistent airflow help make HVAC maintenance, car AC recharging, and vacuum packaging faster, smoother, and more reliable.

Backflow Prevention with Accessible 1/4" Oil Fill Port for Clean Operation

The VEVOR vacuum pump for refrigeration systems features backflow control to prevent oil from returning to the vacuum chamber and contaminating refrigerant lines or storage containers. This will keep the operation cleaner and prevent the system from being contaminated by unwanted contaminants. And oil topping off is quick and easy owing to a 1/4" fill port accessible from the front or either side of the housing, so you never have to move the complete unit for service.

A specialized gas exhaust vent removes vapor from the reservoir and bypasses oil spouts during heavy-duty operation. An incorporated oil drain hole also makes routine oil changes easier for more effective maintenance. These characteristics combine to keep the pump clean between uses and to prevent hazardous accumulation in the dual-stage internals, resulting in a longer-lasting machine. These meticulous details mean reliable functioning in the most demanding conditions.

Oil Viewing Window with Built-In Thermal Protection for Reliable Cooling

The integrated oil viewing window allows professionals to quickly monitor fluid levels without opening the unit, making it easy to spot low oil during busy service calls. Early detection of oil shortages helps avoid dry-running conditions, which can rapidly damage internal seals and rotors. Maintaining proper lubrication levels through routine checks ensures the vacuum pump operates smoothly and reliably.

Built-in thermal protection keeps the copper windings from burning out during long evacuation cycles by monitoring motor temperature and cutting power if overheating is detected. This self-cooling feature extends the vacuum pump’s operating life for refrigeration applications, reducing maintenance costs. Technicians can confidently perform deep-evacuation work for extended periods without stopping for manual checks or temperature monitoring.

15-Micron Factory Rating with 5Pa Ultimate Vacuum for Precision Performance

The vacuum pump for refrigeration system is rated at 15 factory microns and 5Pa (0.05 mbar) ultimate vacuum and is perfect for evacuating moisture and non-condensable gases from sealed lines. Its two-stage rotary mechanism reaches these deep vacuum levels more reliably than single-stage equivalents. This means there is less residual moisture trapped in the line after servicing, resulting in excellent quality HVAC work.

Dual 1/4" SAE and 3/8" SAE inlet ports allow technicians to connect directly to conventional refrigeration hoses and manifold gauges without additional adapters. This makes both home and commercial equipment easier to set up and saves time on every job. This ensures a more consistent vacuum on each evacuation cycle, whether you are servicing a home fridge or a huge industrial machine.

Ergonomic Grip Handle with Shockproof Base for Easy Portability

The ergonomic grip handle provides a comfortable hold. It also makes it easy to lift and transport the pump between job sites, service trucks, or rooftop units. Even during long shifts with frequent moves, the handle design distributes weight evenly across the palm. This reduces wrist and forearm strain for technicians working extended hours.

A shockproof base absorbs vibration and impacts during shipment or when the motor operates on uneven surfaces, keeping the device steady and reducing wear on internal components over months of frequent use. Combined with the compact aluminum alloy housing, this robust foundation enables the pump to endure the bumps and drops common in mobile HVAC, refrigeration, and automotive repair work, day after day, season after season.

Wide-Application Vacuum Pump for Refrigeration System and HVAC Maintenance

This versatile vacuum pump for refrigeration systems is ideal for maintenance and can handle a wide range of tasks, including automotive AC repair, vacuum packaging, and residential refrigerator evacuation. Its 9.0 CFM flow rate and 300ml oil capacity support both quick jobs and extended industrial sessions. Users benefit from fewer oil top-offs between service calls and reliable performance across settings and skill levels.

This combination of dual-stage suction, accessible oil ports, and consistent thermal cooling makes it suitable for both residential and commercial refrigeration lines. Technicians, hobbyist mechanics, and facility maintenance teams all benefit from its user-friendly design. Its adaptability ensures high performance across a range of applications.
