The HF series monitor nozzle is a water powered system that proportions and delivers either water or foam to the hazard area. The HF series monitor nozzles are available at flow rates of either 350 or 500 gpm (1,325 or 1,893 Lpm) @ 100 psi (6.9 bars). Nozzles feature brass construction with stainless steel trim, a 2.5” (F)NH swivel Water inlet and a 1” (M)NPT foam concentrate inlet. Discharge pattern is fully adjustable from straight stream to full fog. Foam concentrate is proportioned directly from an atmospheric source via self-eduction, metered with interchangeable orifice plates for 0.5%, 1%, 3% and 6%.
