Tank Foam Chamber

forede® Foam Chamber is an air aspirating foam discharge device, it contains a vapour seal to prevent the entry of fuel vapour into the foam chamber and the foam solution pipe. Each foam chamber is supplied with an orifice plate, designed for the required flow and inlet pressure. The orifice is field replaceable in the event of change in design parameters. Foam is produced by introducing air into the foam solution stream. The inlet of foam chamber is designed to create venturi jet which draws air into the foam solution stream. Air is drawn into the foam solution through the holes located on the foam chamber covered with stainless steel screen to exclude nesting birds and insects. The aerated foam is directed into the deflector for gentle application of the expanded foam. The deflectors are available in different models.
