VNS
VNS Self Inducting Monitor Nozzle – UL
The “VNS” self inducting nozzle will use the flow of water through the internal waterway to draw foam into the nozzle and mix into a foam solution locally before discharging from the outlet. The foam induction can be isolated using the supplied ball valve and water only can be used. The total flow in this condition will be 3% less than nominal. ; ; Smaller flow nozzles are available in anodized aluminium and nickel aluminium bronze with flow rates of 250, 350 and 500 GPM. For the larger flow rates of 750 and 1000 GPM the nozzle is available in stainless steel only.
