Manual Fire Monitors

The KRF-LS Fire Monitor with manual control discharges jet of water or foam solution with a variable discharge pattern from stream up to 120 degrees, creating a wide fog.

The KRF-LS Fire Monitor with manual control discharges jet of water or foam solution with a variable discharge pattern from stream up to 120 degrees, creating a wide fog.

KRF-LS is equipped with control handwheels which ensure movement of the monitor’s body and its precise positioning in horizontal and vertical planes. The crossed-axis helical gear that is used to control the monitor is designed to significantly increase the torque and, accordingly, reduce the operator’s efforts when using the control handwheel. The cross-axis helical gear has a self-locking effect and is irreversible, which provides the possibility of fixation in any intermediate position in the range of movement without additional devices for fixing the monitor position.

Monitor’s materials

All materials contain mechanical and corrosion-resistant properties that meet the operating conditions and meet the requirements for monitors

Notes: *- : Values are given at a pressure of 8 bar; **- Jet ranges are given at an angle of inclination of the monitor to the horizon of 30°, set in the working position.
