NAVAC NP12DA1 Ammonia Vacuum Pump - 12 CFM, 5 Microns, Dual Stage | Industrial dual-stage vacuum pump is corrosion-resistant for ammonia R-717 and delivers 12 CFM flow with 5-micron vacuum.

Highly corrosion resistnt. NAVAC NP12DA1 is an Ammonia-rated (R-717) vacuum pump built with special corrosion-resistant internal parts and a stainless steel inlet port, allowing HVAC technicians to use ammonia to service large commercial refrigeration.

Robust opump. Equipped with brushless DC technology, a power supply of 115V/60Hz, 1/2 HP motor power, and an ignition-proof electronic starter for a lighter and more efficient vacuum pump.

Built-in check valve. The NP12DA1 Ammonia Vacuum Pump also features an internal check valve that holds the vacuum and oil when the power turns off or is interrupted unexpectedly, preventing oil backflow that can damage the pump.

Industrial-grade design. With its dual-stage rotary vane pump, NP12DA1 performs a faster evacuation of 12 CFM flow rate and a deeper vacuum down to 5 microns. It is heavy-duty for industrial applications.

Encouraging smart work. We want your NP12DA1 Ammonia Vacuum Pump to last as long as it can, which is why we are offering a 1-year warranty. NAVAC always wants to empower you to work smarter!
