Foam Chambers are air aspirating devices used for the protection of fixed roof flammable liquid storage tanks. This method consists of one or more foam chambers installed on the shell of the tank just below the roof joint.

A foam solution pipe extends from the proportioning source outside the dike wall to the foam maker located upstream of the chamber. Foam Chambers are widely used with the line proportioned and bladder tank / balanced pressure pump in low expansion foam system. Upon entering the chamber the foam solution is expanded and then discharged against a deflector mounted inside.
