Induction centrifugal fans ICF are designed for general purpose ventilation of underground and semi-opened parkings, smoke extraction in case of fire as a part of smoke extract system. The fans generate a high-speed and high-pressure directed air jet.
ICF casing is made of polymer coated steel. Due to low height of the casing the fan is recommended for use in low-ceilinged room. The protecting grille on the intake side prevents ingress of foreign objects into the fan. Deflector plates on the exhaust side of the fan ensure correct air flow distribution.
Single- or double-speed 4-, 6- or 8-pole asynchronous motors are used. The motor ingress protection rating is IP55. The motors are rated for 400 V power mains voltage and 50 Hz frequency.
The impeller with backward curved steel blades.
ICF fans are designed for ceiling mounting and fixation by means of the supplied fixing brackets. Power is supplied through the internal terminal box. The fan wiring and mounting must be made according to the instructions and the wiring diagram shown in the terminal box.
