Nozzles – Air aspirating Foam-Water Sprinklers
HD Pendent & Upright Foam-Water Nozzles are air-aspirating foam discharge sprinklers engineered for use in foam-water deluge systems, providing an efficient and effective solution for fire protection involving flammable and ignitable liquid hazards.
These nozzles are designed to discharge foam from overhead, followed by a secondary discharge of water in a spray pattern similar to standard sprinklers. This dual-action performance ensures rapid fire suppression along with cooling and secure extinguishment.
In operation, the foam solution (water mixed with foam concentrate) flows through the nozzle, where air is inducted to generate air-aspirated foam. The mixture is then agitated within the nozzle body and discharged in a pre-determined pattern for optimal coverage and performance.
HD Foam-Water Nozzles are suitable for applications requiring reliable foam generation and distribution from overhead systems. HD Pendent Foam-Water Nozzles are UL Listed and FM Approved, while HD Upright Foam-Water Nozzles are UL Listed. These nozzles are also UL Listed with HD AR-SFFF F3 3×3% Fluorine-Free Foam.
