Model VFM Foam Makers
Foam Makers are in-line fixed foam aspirating devices. They are used in low expansion foam discharge applications to protect tank farm dikes and other low-level discharge applications.
Foam Makers are used in the dike foam delivery system as referred to in design standards such as NFPA 11. The foam makers are part of a low-level foam delivery system that also incorporates foam storage bladder tanks, proportioning devices and suitable foam concentrates.
Foam solution can also be supplied by foam pumping systems or in semi-fixed systems supplied from a portable supply such as a fire brigade appliance.
Foam Makers are FM approved with the Viking USP concentrate (Hydrocarbons only) at an application rate of .1 gpm/sq ft.
Foam makers are FM approved with the Viking ARK concentrate (Polar solvents & Hydrocarbons) at the following application rates:
Hydrocarbons & Acetone .2 gpm/sq ft.
Isopropyl Alcohol (IPA) .25 gpm/sq ft.
Ethanol .16 gpm/sq ft.
