The TFSK range consists of roof fans with a square base frame and are fitted with a single-inlet centrifugal fan with backward-curved blades and external rotor motors. The motors can be tilted outwards to facilitate inspection and service. They have integral on/off switch and are supplied with 1 m cable and are easy connected to our standard roof curbs TG, FDS and SSD.
These fans are suitable for exhaust-air ventilation systems, e.g. single and multiple dwellings, offices and day nurseries. To protect the motors from overheating, all motors have an integral thermal contact with electrical reset. The casings are manufactured from galvanized steel, with powder-coating in black colour.
For cold climates we recommend that the fan runs continuously to avoid problems with ice.
In case of installing FSD-L flat roof socket, a TDA adapter is needed.
