The Mod. LSAC is a high back pressure foam generator used with low expansion foam concentrate to inject foam in subsurface applications for fixed cone tanks. The combination of the foam solution delivered to the foam generator and the self induces air generates the foam which is then delivered on the tank bottom and injected into the combustible product. The Mod. LSAC is available in carbon steel and stainless steel, with ANSI or UNI flanges.
