The Pyro-Chem Monarch N-LA-BC Nozzle (P/N 550342) is an overhead local application BC dry chemical nozzle for the Pyro-Chem Monarch Industrial Dry Chemical Fire Suppression System. It is the BC dry chemical counterpart to the N-LA-ABC (P/N 550646), which uses ABC dry chemical. BC dry chemical (rated for Class B and C fires only) is specified in certain industrial hazard applications where the monoammonium phosphate in ABC dry chemical could cause corrosive damage to specific materials or equipment in the protected area. The N-LA-BC nozzle is positioned overhead and aimed downward at a specific surface hazard. Ships with a blow-off cap. For full background on the Pyro-Chem Monarch system, refer to the NV-SW Work Area Nozzle product page (P/N 552175).
