With industrial-grade technology, NP12DA1 solves the problems of long-time evacuation, inadequate vacuum level in the service for large commercial refrigeration or central AC systems. The special design with corrosion-resistant pump parts and stainless steel inlet port makes the pump suitable for ammonia (R-717). The dual-stage rotary vane pump and inverter motor lead to faster evacuation and a deeper vacuum. Integrate pump structure and built-in oil back-flow prevention assure superior performance and reliability.
