  • NAMD-1 Pressure Maintenance Device is a Factory Mutual (FM) Approved device designed to automatically regulate and maintain the flow of air or nitrogen into dry-pipe sprinkler systems or preaction sprinkler pipe.
  • CMA-1 Corrosion Monitor Assembly is a device for monitoring the possible corrosion inside of a wet or dry sprinkler system piping.

Our NITROGEN-PAC™ is a fully integrated nitrogen generator system that introduces high-purity nitrogen into preaction or dry sprinkler piping. It replaces the existing air compressor, providing the necessary supervisory pressure in the form of nitrogen instead of air.


PREACTION-PAC™ is a Factory Mutual (FM) Approved, fully integrated preaction fire suppression assembly. This preaction cabinet includes a preaction valve, compressor, and control panel providing one complete zone of preaction water sprinkler fire protection.


Our STANDPIPE-PAC™ is a fully assembled standpipe supervisory system, including compressor, switches, alarm, and control unit providing one complete zone of standpipe supervision. It is in compliance with New York City’s Local Law 64 and the Boston Fire Department’s TCM3-51725.


We also offer a line of Sprinkler Accessories, including: the Air Vent for Wet Sprinklers Model AR-1, the Pressure Maintenance Device Model NAMD-1, Corrosion Monitor Assembly Model CMA-1, and Riser-Mount Air Compressors Model RMAC-LP.
