Nozzles – Air aspirating Foam-Water Sprinklers
HD Pendent & Upright Foam-Water Nozzles are air-aspirating foam discharge outlet sprinklers designed for use in foam-water deluge systems.
They are designed for flammable liquid risks where it is desired to apply foam from overhead sprinklers and where follow-up with plain water in a standard spray sprinkler pattern is necessary. These are designed to discharge foam in a pre-determined discharge pattern. HD Pendent Foam-Water Nozzles are UL Listed and FM Approved. HD Upright Foam-Water Nozzles are UL Listed. These are now UL Listed with HD AR-SFFF F3 3×3% Fluorine-Free Foam.
