WILLIAMS FIRE & HAZARD CONTROL® (WILLIAMS) LWNS Series monitor nozzles are patented water-powered nozzle systems that deliver either water or foam to the hazard area. The discharge pattern is fully adjustable from straight stream to full fog.
Each nozzle is supplied with interchangeable orifice plates for proportioning at 0.5%, 1%, and 3%. Foam concentrate is proportioned directly from an atmospheric storage tank using the self-eduction function or from a remote foam concentrate supply in conjunction with a matched Jet Ratio Controller at 1% or 3% only.
LWNS nozzles feature a brass construction with stainless steel trim. These nozzles have a 2 1/2 in. (F)NH swivel inlet and a 1 1/2 in. (M)NPT foam concentrate inlet. These three models are available with standard flows rates of 350 gpm (1,325 Lpm), 500 gpm (1,893 Lpm), or 750 gpm (2,839 Lpm) at 100 psi (6.9 bar), respectively
