WFN foam-water sprinklers models are air-aspirating foam discharge outlets designed for use in foam-water deluge systems. This equipment is the perfect solution when foam application from overhead sprinklers is necessary and where a follow-up with plain water in a standard spray sprinkler pattern is needed, as per NFPA 16 requirements. Equipment are produced in cast or handmade bronze or by welding using stainless steel materials to fulfill corrosion resistance requirements. Connection to the fire protection network is threaded NPT or BSP with a size of DN 15- ½”. Flow rates are factory calibrated and tested according to request up to Metric K factor 59 l/min * bar1/2. Upright or pendent configurations are available to fulfill project requirements.
