FoamPro® 1601 Foam Proportioning System & Low-Level Switch
The FoamPro® 1601 is an electronically controlled, discharge-side Class A foam proportioning system for slip-on pumpers, brush rigs and other fire apparatus. It measures water flow and injects concentrate to maintain the selected percentage as flow changes. Select the FoamPro 1601 System (SKU 11914) or the separately sold Side-Mount Low-Level Switch (SKU 11915). Each selection is a separate item.
