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 in. ACME, 1/4 in. SAE, and 3/8 in. SAE ports, plus 2-R410a 1/4 in. male to 5/16 in. female fitting adapters and 1-1/4 in. male to 1/2 in. female fitting adapter, ensuring compatibility with R134a, R12, R22, R502, and R410a systems. Equipped with a 3/4 HP high-torque, 2-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. Weighing just 17.6 lbs. this pump is easy to carry with an ergonomic handle and non-slip feet.
- 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
- Die-cast aluminum housing minimizes leaks, while the visible oil window allows easy monitoring of oil levels
- 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
- 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
- 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
- Easily identify the high-pressure (red), low-pressure (blue), refrigerant adding(yellow), and vacuuming(black) hoses
