HOSE REEL SYSTEM: FIRE FIGHTING INSTALLATIONS
TYPICAL HOSE REEL: FIRE FIGHTING INSTALLATIONS
General purpose synthetic delivery hose. Suitable for industrial and rural fire brigades as well as static building protection.
General industrial, commercial and civil engineering applications including waterauthorities where a high burst performance hose is not necessary
Lightweight and flexible Heat and cold resistant Anti rot and anti-twist
Synthetic Delivery Nose : FIRE FIGHTING INSTALLATIONS
Branch pipes provide an adjustable nozzle to allow the curtain of water to be altered from a narrow spray to a wide spray.
Nozzles provide a fixed jet of water. The basic branch pipe according to BS336 has an 21/2" inlet male instantaneous and outlet threaded 11/3" BSP male for either a plain jet or a branchpipe adjustable nozzle.
The branch pipe is controlled from SHUT-OFF through JET and SPRAY to wide angle CURTAIN by rotating the annular sleeve.
