The TFSR range consists of roof fans with a circular base plate 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 for fast connection to the mains e.g. via the connection box on the roof curb TOB or TOS.
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 automatic reset. The casings are manufactured from galvanized steel, with powder-coating in black colour.
TFSR 125-160 are delivered with a ? 160 spigot and TFSR 200-315 with a ? 200.
For cold climates we recommend that the fan runs continuously to avoid problems with ice.
