GW - Model M5 - Water Mist Nozzle K-5, Low Pressure, Non-Automatic
From Water Mist
Low Pressure Water Mist Fire protection nozzle. FM tested with Bureau Veritas MED approval, CCS, Lloyds's Register, ClassNK, US Coast Guard and RINA. The GW M5 is a compact low pressure water mist nozzle specifically developed for use in total and local
protection water mist fire extinguishing systems – both for marine and land based applications.
The nozzle is designed to efficiently produce a fine mist of small water droplets at low pressure (3,5 to 16 bar). This makes the nozzle suitable for a large variety of fire protection applications, where fuel pool and high pressure spray fires may occur. Relevant applications are:
- engine rooms
- engine test bench
- turbine enclosures
- paint booths
- cable tunnels
- switch board installations
- other enclosed occupancies with limited draft conditions, suitable for fire-protection with water mist.
If required, the GW M5 water mist nozzle can be used in AFFF (aqueous film forming foam) enhanced systems.
The GW M5 water mist nozzle is fitted with a robust stainless steel protective cap to prevent any damage to the deflectors during handling, installation and service. The protective cap is specification tested by FM and is designed to remain in place after nozzle installation, thus effectively protecting the nozzle orifices from clogging caused by external contamination.
The protective cap is fitted with a high quality virgin PTFE bush to provide reliable low friction ejection (Blow-Off) when the water mist system is activated and water is discharged.
The GW M5 water mist nozzle is as standard fitted with a SS316 wire mesh strainer in the nozzle inlet, to prevent water born debris from entering the nozzle and clogging of the orifices.
