Open, air-aspirating foam-water sprinkler designed for use in deluge foam systems, delivering foam followed by plain water in a standard sprinkler discharge pattern. Available in stainless steel (F1) or bronze (H) construction, the F1-H protects loading and unloading areas from spill fires using low expansion foam systems, and is well suited to wide-area applications such as aircraft hangars and warehousing.

Fitted with a standard K-42 orifice, the sprinkler delivers approximately 61 LPM at 2 bar pressure, with a standard coverage of 9.3 sq.m. (100 sq.ft.) per sprinkler — providing reliable, code-compliant protection for deluge foam-water systems.

Materials:

Foam-Water Sprinklers must be stored and shipped in original packaging, and should be installed using Teflon tape or soft thread sealant — avoid excessive tightening torque, which may damage the sprinkler arms or deflector and affect spray performance. It is recommended that the system be inspected regularly and flow-tested at least twice a year, or as required by NFPA or the authority having jurisdiction.
