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.
