The Scotty 4010-50 Fast Foam unit is a foam applicator made with the professional fire-fighter in mind. This higher flow unit is designed to be attached to 38mm hose. The Fast Foam Unit will flow water at a rate of 50gpm (190 lpm) when attached to a standard 38mm fire hose. The unit is recommended for use with water pressures between 520 and 860 kPa.
To operate, simply insert the stick into the applicator and attach to a supply hose and spray Class A foam. As water passes from the pump through the applicator, the stick will dissolve, generating Class A Foam with excellent wetting ability.
Cartridges are sold separately from the applicators.
