Buckeye Foam makers are designed to be an air-aspirat- ing discharge device used primarily for the protection of the seal area of open top floating roof tanks and dike ar- eas around tanks. The foam maker incorporates a mixing barrel, an orifice plate (sized for the required flow at a given pressure) and an air inlet. The foam maker is nor- mally installed in the line of a semi-fixed or fixed foam fire protection system.
