1/2HP 5CFM AC Vacuum Pump Kit w/ Manifold Gauge Set R134a R1234yf HVAC Service For Sale

Safe for A2L Refrigerants • 15 Microns Vacuum • Complete HVAC Kit • ±1.6% Accuracy Gauge

This AC vacuum pump kit and HVAC vacuum pump system is designed for fast and efficient auto AC service, air conditioning evacuation, and refrigeration maintenance. Featuring a 5 CFM dual-stage vacuum pump and a precision manifold gauge set, it delivers professional-grade performance for automotive AC and HVAC applications.

Sparkless Dual-Stage Vacuum Pump - 5 CFM Performance
Equipped with an ignition-proof ON/OFF switch and sparkless motor for safe operation with A2L refrigerants (R32, R1234yf, R454B) and other mildly flammable refrigerants. Powered by a 1/2 HP (375W) motor at 3456 r/min, delivering 5 CFM flow rate and achieving 15 microns vacuum level in just 3 minutes. Designed for accurate AC system evacuation and maintenance.

Wide Refrigerant Compatibility
Features dual 1/2" ACME and 1/4" SAE ports, plus four adapters (2× 1/4" male to 5/16" female for R410a, 1× 1/4" male to 1/2" female, and 1× 1/4" male to 1/2" female left-hand). Compatible with R32, R1234yf, R454B, R410a, R134a, R12, R22, and R502 air conditioning systems. Ideal for HVAC servicing, vacuum packaging, oil distillation, and resin defoaming.

Safe & Quiet Operation
Motor current protection helps prevent overload and overheating. 304 stainless steel coarse filter blocks contaminants from entering the pump chamber. Oil mist cap and exhaust cotton filter capture oil mist and reduce operating noise below 65 dB for a cleaner workspace.

User-Friendly & Durable Construction
Features an ergonomic handle and non-slip feet for easy transport. Integrated die-cast aluminum housing reduces leaks. Visible oil window and bottom drain valve simplify maintenance and monitoring.

±1.6% Accuracy Manifold Gauge
Ensures precise pressure measurement for refrigeration systems. Combines the best of dry and liquid-filled designs with an oil-filled core to resist wear and a dry dial for better winter performance. Large sight glass allows clear refrigerant flow visibility. Color-coded gauges ensure accurate readings for refrigerant charging, diagnostics, and coolant recovery.

Durable Gauge Construction
Built with a shock-resistant core to protect internal mechanisms. Includes a calibration screw for zero-setting and scales for R32, R410A, R1234yf, and R134a refrigerants. Rubber-wrapped design ensures durability, while the aluminum body adds strength. Convenient hook allows for hands-free operation, making it both tough and practical.

3 Color-Coded Hoses
Easily identify the high-pressure (red), low-pressure (blue), and refrigerant adding (yellow) hoses. Made of 3 reinforced rubber layers with a leak-proof seal, these hoses are flexible, durable, and resistant to damage. Ideal for maintaining R32, R1234yf, R454B, R410a, R134a, R12, R22, and R502 air conditioning systems.
