Sprinkler F1

HD Pendent Foam-Water Sprinklers are air-aspirating foam discharge outlets 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. Foam sprinklers are designed to discharge foam in a pre-determined discharge pattern, as well as to discharge water similar to standard spray sprinklers. HD foam-water Sprinklers are UL Listed and FM Approved. •Air aspirating type •Bronze or Stainless Steel Material •Finish: Natural Bronze or Staintless Steel •Size: 1/2" BSPT / NPT •Effective working pressure: 2.1 bar to 4.2 bar (30 to 60 PSI) •K-factor 2.95 (42 Metric) •Pendent mounting •UL Listed and FM Approved APPLICATION The Foam-Water Sprinklers are used in the deluge foam system to protect the risk where foam is required to be applied from overhead sprinklers and is to be followed with plain water in a standard sprinkler pattern. Foam-Water Sprinklers protect the loading and unloading area in the event of a spill fire with low expansion foam systems. These are useful in other applications like Air Craft Hangers, Warehousing etc. SPECIFICATION Foam-Water Sprinklers are open and air aspirating type. The pattern of coverage is similar to the conventional sprinkler head. The Foam-Water Sprinkler has standard orifice with K-factor of 42. The Foam-Water Sprinklers are designed to operate at a minimum of 2.1 Bar pressure and maximum of 4.2 Bar pressure. The Foam-Water Sprinkler with K-42 will deliver about 61 LPM at 2.1 Bar pressure.
