NAVAC introduced a robust, corrosion-resistant vacuum pump designed to guard against the damaging effects of ammonia-based refrigerants. Part of the company’s Master Series of HVAC/R solutions, the NP12DA1 Ammonia Vacuum Pump combines protection with power via an impressive flow rate of 12cfm for fast, heavy duty performance.
Anhydrous (dehydrated) ammonia, which is commonly used in industrial facilities as a refrigerant for cooling and freezing, is a highly corrosive substance. In fact, its widespread use as a refrigerant is one reason why vacuum pumps have, historically, been considered disposable HVAC tools. The new NAVAC Ammonia Vacuum Pump pushes back against this wasteful trend with a stainless-steel inlet port and corrosion-resistant pump, protecting against ammonia’s adverse effects for a significantly lengthened product lifespan.
NAVAC’s NP12DA1 Ammonia Vacuum Pump features an industrial-grade design for a rare blend of robustness, speed and power. Its brushless DC-motor technology maintains peak efficiency while yielding a superior starting performance under low starting amperage and soft-starting down to 30°F, and its twin-cylinder functionality and precision manufacturing provide an industry-leading ultimate vacuum down to 5 microns.
Other features and benefits of the NP12DA1 include adjustable gas ballast for superior moisture handling capability, high-performance oil mist filter for a clean environment while saving pump oil, a recessed power switch safeguarding against tripping and rain, ball-valve oil drainage design, and a low operating sound level.
