mcr Monsun R axial fans are used in fire ventilation systems for smoke exhaust and air supply, where reversibility of the system or explosion-proof making is required.

Smoke fans are used for removing heat, smoke and combustion gases generated in rooms during fire. They facilitate evacuation of people from fire zone, as well as fire fighting operations carried out by fire brigades. They also protect the building structure and its equipment from the effect of high temperature, and prevent spreading of fire to adjacent areas.

The devices are adapted for outdoor, as well as indoor operation.
