LSF model foam makers are designed as an air aspirating equipment for fixed applications commonly used against hydrocarbon or polar solvent fires for dyke are protection, open floating roof storage tanks and rim seal areas where low velocity expanded foam flow is required. This equipment is usually installed to fire protection lines at the point of discharge, and fed by a premixed foam solution. LSF foam makers are designed with a calibrated orifice plate to determine the equipment’s flow rate. Its special orifice plate creates an air vacuum effect and the foam solution expands after being sprayed through the discharge port of the equipment. LSF model foam makers can be produced to discharge up to 3200 l/min @ 5 bar inlet pressure whilst special flow rates are available on request. LSF model foam makers can be combined with FP or FP-I type pourers to pour expanded foam concentrate gently onto liquid surface. For special applications, this equipment may be used for Over Top foam application for storage tanks as the foam maker part. Air aspiration port is protected with anti-volatile mesh. Carbon steel & Stainless Steel maetrials are available according to project requirements.
