USAFE Foam Chambers are air aspirating devices used for the protection of fixed roof flammable liquid storage tanks. Foam chambers are widely used in low expansion foam system defined by NFPA 11.

They provide the means to aerate the foam solution and allow foam to gently fall onto the liquid surface in the tank. At the same time, they incorporate arrangement to prevent the product vapours inside the tank from leaking out into the atmosphere.
