SPECSTAR 3 /4 HP 7.2 CFM 2 Stage HVAC Vacuum Pump and 4 Way AC Manifold Gauge Set with Leak Detector 5ft Hoses & Accessories for R134a R12 R22 R502 R410a Auto Air Conditioning Refrigeration Recharging

Features

• DUAL-STAGE HVAC PUMP: The dual-stage vacuum pump delivers deeper vacuums by creating a preliminary vacuum followed by further pressure reduction, making it ideal for demanding HVAC applications that require precise control; It features 1/2 ACME, 1/4 SAE, and 3/8 SAE ports, plus two R410a 1/4 male to 5/16 female fitting adapters and one 1/4 male to 1/2 female fitting adapter, ensuring compatibility with R134a, R12, R22, R502, and R410a systems
• POWERFUL MOTOR: Equipped with a 3/4 HP high-torque, two-pole copper motor, the HVAC vacuum pump delivers 3456 RPM and a 7.2 CFM flow rate, evacuating systems down to 0.2 Pa (1.5 microns) in just 3 minutes for faster, more efficient performance and thorough evacuation
• 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, and the dual-stage design reduces heat buildup, 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
