Foam Water Sprinkler B-1

The Model B-1 Upright and 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 (either upright or pendent) and where follow-up with plain water in a standard spray sprinkler pattern is necessary. See NFPA 16, “Standard for the Installation of Foam-Water Sprinkler and Foam-Water Spray Systems,” for more information.

The Model B-1 Foam-Water Sprinklers are designed with a unique venturi-style body. As foam solution (water and foam concentrate mixture) flows through the inlet of the body, air is drawn into the body through the openings adjacent to the wrenching area. The foam solution and air mix is then agitated to create an air-aspirated foam.
