TFT's PRO/pak foam injection and application system is the ideal choice with any Class A, AFFF or Alcohol Resistant foam concentrate. Everything you need is contained in one package that attaches to the end of your 25 or 38 mm (1 or 1½") fire hose. The PRO/pak has a high impact 9.5 l (2.5 gal.) foam reservoir with a built-in eductor that can be set to the ratio of foam or wetting agents being used. A large, easy-open fill port has an indicator to show the type of liquid in the tank. Flow is controlled by a twist grip valve that also functions as a carrying handle. With three different quick connect nozzles included, the PRO/pak system is capable of producing low or medium expansion finished foam, while operating at low inlet pressures.
