The POK "MIXY" inline foam eductor draws foam concentrate into the water stream by venturi suction, producing a consistent foam solution for Class B and flammable-liquid firefighting. An adjustable brass metering device sets induction from 0–6%, and a non-return valve prevents back-flow. The aluminium-alloy body carries a 50 µ Teflon-impregnated anodised finish plus polyester coating for strong resistance to mechanical and chemical attack. Installs between the pump and the foam branchpipe.
