Tulderhof - Insulated Fan Doors Brochure

Insulated fan doors from Tulderhof fit most V-belt driven exhaust fans. The doors are made out of 2 mm formed steel. On one side a thick 18 mm insulation layer is glued. The soft insulation layer closes draught free on the frame of the exhaust fan. The door can be closed with a key. A hollow pipe is optional and is used as a support when the door is open (see picture).
