Ventalu forced ventilation DR-S


This forced ventilation attachment significantly speeds up the dehumidification of roof systems planned for refurbishment. As an extension for cold roof fans, the Ventalu forced vent generates negative pressure through wind propulsion to provide efficient ventilation of the roof system and consequently significantly contributes to dehumidification. The extraction fan is capable of achieving a high air flow and protected against driving rain and snow.


The Ventalu extraction fan attachment is made from top quality aluminium alloy.
