Systemair TOV 450-4 Roof fan

Speed-controllable

Integral thermal contacts

Tilting mechanism on motor

Maintenance-free and reliable

Vertical exhaust

The TOE/TOV models have impellers with backward-curved blades and external rotor motors. The casing is manufactured in powder-coated galvanised sheet steel. These fans have motors which can be tilted outwards to facilitate inspection and servicing.

The motor is suspended on efficient vibration dampers. Exhaust air is directed vertically from the fans, which prevents problems caused by wet snow and staining of the roof.

To protect the motor from overheating, the TOE/TOV fans have integral thermal contacts with external leads for connection to a motor protection device.
