NAVAC NP12DA1 12 CFM Ammonia Vacuum Pump Industrial Grade

The NAVAC NP12DA1 is a robust, corrosion-resistance vacuum pump designed to guard against the damaging effects of ammonia-based refrigerants. The NAVAC NP12DA1 vacuum pump combines protection with power to provide an impressive flow rate of 12 CFM for fast heavy duty performance.

 

The NAVAC 12 CFM ammonia vacuum pump features an industrial-grade design to provide better evacuation and vacuum for the service of large commercial refrigeration or central AC systems. The brushless DC motor technology maintains peak efficiency while yielding low starting amperage and soft-starting down to 30°F. The dual-stage rotary vane pump and inverter motor lead to faster evacuation and a deeper evacuation down to 5 microns.

Anhydrous ammonia (R-717), a highly corrosive substance, is commonly used in industrial facilities as a refrigerant for cooling and freezing. Ammonia-based refrigerants are prevalent in meat, poultry, fish processing facilities, cold storage warehouses, and petrochemical facilities. To protect against ammonia adverse effects, the NAVAC NP12DA1 has a stainless-steel inlet port and corrosion resistance pump parts to significantly lengthen the vacuum pump's lifespan.

Due to the corrosive nature of ammonia refrigerants, NAVAC NP12DA1 uses KF25 fittings on both the exhaust and intake ports. However, if desired, an oil mist filter can be purchased separately for the exhaust port but should not be used with ammonia or corrosive refrigerants.

Other features include adjustable gas ballast for moisture handling capabilities, a recessed power switch safeguarding against tripping and rain, a ball-valve drainage design, a large oil sight glass to eliminate oil shortages, and a lifting hook for easy hoisting.
