Ansul's Flowmax PPW is a variable range proportioner that utilizes a variable orifice to meter an accurate flow of liquid foam concentrate over a wider range of flows and pressures than standard balanced pressure pump proportioners.
The units are available in 6-inch and 8-inch sizes with flow rates from 55 to 4,875 gpm (208 to 18,453 lpm). Each unit consists of a foam proportioner with integral pressure balancing valve, and pressure sensing tubing. The proportioner construction includes a bronze body, stainless steel deflector, stainless steel spring, stainless steel foam metering cone and orifice, and a bronze balancing valve with stainless steel fasteners.
Ansulite AFCB 3% AFFF and Ansulite A334-LV 3X3 AR-AFFF are the only concentrates UL-listed and FM-approved for use with the Flowmax PPW proportioners.
