High Vacuum 5.0CFM Car AC Vacuum Pump 1440RPM Single Stage HVAC Auto Air

This 5.0CFM high vacuum car AC vacuum pump delivers professional-grade evacuation performance for automotive air conditioning system service. Operating at 1440 RPM with a single-stage rotary vane mechanism, the pump achieves deep vacuum levels essential for complete moisture and air removal from AC systems prior to refrigerant charging. The 5.0 cubic feet per minute displacement rate ensures fast evacuation of passenger car and light truck AC systems, minimizing service bay turnaround time while maintaining the vacuum quality standards required by vehicle manufacturers.

The pump features a precision-machined rotary vane assembly housed in a rigid cast aluminum body with integrated cooling fins for optimal heat dissipation during extended operation cycles. The direct-drive motor coupling eliminates belt slippage and power transmission losses, delivering consistent pumping speed throughout the evacuation process. An internal oil circulation system with a large 450ml oil reservoir ensures continuous lubrication of all moving components, extending service intervals and protecting the precision-machined internal surfaces from wear during sustained high-vacuum operation.

The integrated gas ballast valve allows controlled air ingestion during the initial evacuation phase to prevent moisture condensation within the pump oil, a critical feature for maintaining deep vacuum capability when servicing systems in humid climates or after system component replacement where atmospheric moisture ingress has occurred. The oil sight glass provides at-a-glance verification of oil level and condition, enabling technicians to perform timely oil changes that preserve pump performance and longevity.

• 5.0CFM High Displacement Rate: Large displacement capacity ensures rapid evacuation of vehicle AC systems, reducing typical passenger car service time to under 15 minutes for reaching deep vacuum levels.
• Single-Stage Rotary Vane Mechanism: Proven rotary vane pump technology delivers reliable deep vacuum performance with ultimate vacuum capability of 5 Pa (0.05 mbar), exceeding OEM AC service specifications.
• Durable Cast Aluminum Housing: Rigid aluminum body with integrated cooling fins provides structural integrity and effective heat dissipation, enabling continuous operation without thermal degradation of performance.
• 450ml Large Oil Reservoir: Generous oil capacity supports extended operation between oil changes, with an anti-splash return design that minimizes oil mist carryover into the vacuum line.
• Integrated Gas Ballast Valve: Adjustable gas ballast feature prevents moisture condensation in pump oil when evacuating systems with high humidity content, maintaining deep vacuum capability in all climate conditions.
• Oil Sight Glass Monitoring: Clear sight glass with minimum and maximum level indicators enables quick visual inspection of oil condition and volume without disassembly or guesswork.
• Quiet Operation Design: Precision-balanced rotor assembly and acoustic dampening motor mounts reduce operating noise to 62 dB(A), suitable for workshop environments where multiple bays operate simultaneously.

This vacuum pump is purpose-built for automotive air conditioning system evacuation across a wide range of vehicle types. It is the ideal tool for independent repair shops performing routine AC service, refrigerant recovery and recharge operations, component replacement procedures, and post-repair system commissioning. The pump handles passenger cars, SUVs, pickup trucks, and light commercial vehicles equipped with R134a or R1234yf air conditioning systems. Beyond automotive applications, it is suitable for residential and light commercial HVAC service, refrigeration system evacuation, and laboratory vacuum applications requiring clean, oil-sealed vacuum generation. The pump is compatible with standard AC manifold gauge sets through the provided 1/4-inch and 3/8-inch SAE flare intake ports. It integrates seamlessly into existing workshop equipment configurations and is straightforward to operate for technicians at all experience levels.

Each vacuum pump is shipped with factory-filled and tested oil, ready for immediate use upon delivery. The pump is packaged in a reinforced double-wall corrugated carton with custom-cut high-density foam inserts that protect the unit during transit. The package includes the pump unit, a 450ml bottle of premium vacuum pump oil, intake port protective caps, an operating manual with maintenance schedule, and a quality inspection certificate. We provide a comprehensive 24-month warranty covering manufacturing defects and material failures. Replacement parts including vanes, gaskets, and oil are readily available through our global distribution network. Bulk order packaging with palletized shipping configurations is available for wholesale and OEM private label customers. Our responsive after-sales support team provides technical assistance for installation, operation, and maintenance inquiries.
