The Buckeye Air-Aspirating Handline Nozzle is designed to effectively entrain air into the foam/water solution by a modified venturi process. The aspirated foam provides excellent fire fighting performance and is ideally suited for application to polar solvents. Depending upon the type of foam concentrate used, expansion ratios of 5:1 up to 10:1 can be expected, with a nominal nozzle operating pressure of 100 psi (7 bar). The nozzles are manufactured in aluminum alloy and stainless steel, with a powder coated red finish.
