D-3-4-3 SME medium expansion foam nozzle

SME type medium expansion foam nozzles are used to fight flammable liquid risks on which foam should be applied from an overhead firefighting network. This equipment works in a similar way to GSM model medium expansion foam generators. A stream of foam solution is sprayed at high speed to an expansion net, attracting into the body the required air and producing foam with an expansion ratio of about 1:20. Equipment is made in stainless-steel body with a spray nozzle made in brass. Flow rates are factory calibrated according to request. The connection to the fire protection network is NPT or BSP threaded DN 20- ¾” or DN 25- 1” depending on flow rate.
