They are suitable for use with all foam concentrate types in either salt or fresh water. The monitor is provided with a Gas Spring counterbalance with weather protection bellow to offset the weight of the air aspirating foam nozzles. Type Monitors are in active service from the Arctic Circle to the tropics and in marine applications, such as on-board tankers, oil rigs, docks and piers. Features Cast brass construction for better corrosion resistance. Integrally cast straightener vanes in each elbow section to reduce waterway turbulence and friction loss.
Swivel joints are ball bearing type equipped with O-ring seals to prevent water leakage.
Monitor is designed to eliminate effects of nozzle thrust reaction. Full 360 continuous rotation. Angle of elevation is infinitely adjustable from 60 below horizontal to 90 above. Gas spring type counterbalance to offset weight of air aspirating type foam nozzles. The monitor shall be of a single waterway, cast design with integrally cast straightener vanes in each elbow section to reduce waterway turbulence and friction loss.
