Foam Maker

A) Foam makers are of two types- Fixed Foam Maker ,
B) Foam Maker for Rim Seal

The Fixed Foam Maker is designed to provide the required flow rate of foam solution at a specified inlet pressure. The air inlet provides uniform distribution of air into the foam solution stream to generate expanded foam. The air inlet screen conforms to the body of the Foam Maker and prevents damage by the entrance of foreign material.

The Rim Seal Foam Maker with Foam Pourer is designed to discharge fully aspirated foam directly to the annular seal area of open top floating roof storage tanks for fire or vapor suppression. Fully aspirated foam provides the most effective performance for all types of foam concentrates.
