The TFSK range consists of roof fans with square connection 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 1m 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 automatic reset. The fans are manufactured in powder-coated, galvanized sheet steel and are delivered in the standard colours ofblack or brick red.

DVS / DVSI Vertical Discharge Fan

The DVS/DVSI models have impellers with backward curved blades and external rotor motors. All motors are speed controllable over the voltage. Frequency inverters must have an all pole sine filter. The motors are suspended on effective vibration dampers. DVS/DVSI ...EZ / EV / ES: 1~ motor with connection for 2-speedsDVS/DVSI ...E4: 1-speed motorDVS/DVSI ...DV / DS: 3~ with Y/D-connection for 2-speedsTo protect the motors from overheating the DVS/DVSI up to size 311 have integral thermal contacts, from size 355 with external leads for connection to a motor protection device. The casing is made from aluminum and the base frame is powder-coated galvanised steel. Suitable for coastal applications. The impellers up to size 355 are manufactured from polyamide PA6 25GV, from size 400 in Aluminium.DVS with outlet vertical. DVSI with 50 mm mineral wool insulation for low noise level.
