HE-400-V model dynamic High Expansion foam generators are used for Aircraft Hangar Protection according to NFPA-409, where a reliable driven fan is required to aspirate air. These equipment uses the reaction forces of the spray nozzles to rotate the main rotor and the connected wings, creating a forced aspiration effect to deliver air into the equipment, necessary to expand the foam solution. Rotating elements are isolated from the foam-water solution to avoid any malfunctions and to reduce maintenance needs. This equipment is ideal for usage to feed generators with air ducts. The foam production capacity is up to 322 m3/h. Performance certificates released by third-party organizations are available for these products guarantee the performance against Polar Solvent and Hydrocarbon Fires.
