1/3 HP 4.5 CFM 1-Stage HVAC Vacuum Pump and 4 Way AC Manifold Gauge Set for R134a R12 R22 R502 R410a Auto Air Conditioning
About the product:
POWERFUL PERFORMANCE: The 4.5 CFM single-stage vacuum pump features a 1/3 HP high-torque, four-pole pure copper motor that minimizes wear and maximizes efficiency; With a 4.5 CFM flow rate and the ability to evacuate systems down to 2 Pa in just 3 minutes, it ensures a faster, more thorough evacuation for a cleaner, more efficient process
WIDE COMPATIBILITY: The vacuum pump includes 1/2” ACME and 1/4” SAE ports, along with two R410a 1/4” male to 5/16” female adapters and one 1/4” male to 1/2” female adapter, making it compatible with R134a, R12, R22, R502, and R410a systems; With a 4.5 CFM high flow rate, it’s ideal for 1-3 HP split A/Cs, 1-2 HP central A/Cs, 1-3 HP small commercial A/Cs, and vehicle A/C systems
SAFE & QUIET OPERATION: The thermally protected motor shuts down if it overheats for long-lasting performance; An anti-backflow valve prevents oil backflow during sudden shutdowns, while a current protector safeguards the motor; A high-volume fan, large mesh vent, and T-shaped heat fins enhance heat dissipation, keeping noise levels under 70 dB for a quieter, more comfortable work environment
PORTABLE & USER-FRIENDLY DESIGN: Weighing just 17.6 lbs, this pump is easy to carry with an ergonomic handle and non-slip feet; The die-cast aluminum housing minimizes leaks, while the visible oil window allows easy monitoring of oil levels; A bottom drain valve simplifies maintenance, and the 304 stainless steel coarse filter blocks dust, while the cotton exhaust filter and metal filter remove oil mist
±1.6% ACCURACY GAUGE: This manifold gauge ensures precise pressure measurement for refrigeration systems; It blends the best of dry and liquid-filled designs, featuring an oil-filled core to resist wear and a dry dial for better winter performance; A large sight glass allows clear refrigerant flow visibility, while color-coded gauges ensure accurate readings for refrigerant charging, diagnostics, and coolant recovery
DURABLE & USER-FRIENDLY DESIGN: Built with a shock-resistant core to protect internal mechanisms, this gauge includes a calibration screw for zero-setting and scales for R12, R22, R134a, and R410a refrigerants; Its rubber-wrapped design ensures durability, while the aluminum body adds strength; A convenient hook allows for hands-free operation, making it both tough and practical
4 COLOR-CODED HOSES: Easily identify the high-pressure (red), low-pressure (blue), refrigerant adding(yellow), and vacuuming(black) hoses; Made of 3 reinforced rubber layers with a leak-proof seal, these hoses are flexible, durable, and resistant to damage; Ideal for maintaining R134a, R12, R22, R502, and R410a air conditioning systems
