fire resistance class:
400C / 120 minutes
200C / 120 minutes
versions:
fans with one-gear motors
fans with two-gear motors
purpose:
smoke exhaust axial-flow fans of the CJTHT type are designed to remove smoke and heat generated in enclosed interiors. Due to the construction of the casing, rotor and motor of the fan, these devices can operate in temperatures ranging from 200 to 400oC for two hours. This facilitates the evacuation of people from the affected area, protects the building structure, makes it easier to tackle the fire, as well as prevents it from spreading to the neighbouring fire compartments. In normal operating conditions the fans may perform the function of a mechanical and comfort ventilation system.
