Flat roof refurbishment fans with forced ventilation

Efficient moisture removal through forced ventilation of damp roof systems

Function

This refurbishment fan guarantees high extraction performance with forced ventilation. The wind powered extraction fan is capable of achieving a high air flow and protected against driving rain and snow. The set is supplied fully assembled with an extraction fan attachment installed and can be directly welded onto the roof membrane.

Material

Our fans are available in PVC, FPO/PP and BIT for connection to the matching material used for the roof membrane.
The material compounds used are low-temperature impact resistant, weatherproof and stabilized against ultraviolet rays, oxidative decomposition and thermal ageing.
