The next generation of silenced fans. It is engineered by Systemair to be lighter, quieter and maintain all the advantages of the original Revolution Silenced model. V2 raises the bar and it is the ultimate sound-absorbing fan.

The sealed housing is the culmination of a team of engineers who developed a new and novel solution to reduce the noise of airflow. The fans have silent motors and double-balanced blades.

The V2’s new housing incorporates a sound-reducing foam designed especially for ventilation systems and doesn’t absorb moisture or dust. The metal flanges are inserted into the housing with rubber grommets, forming a seal. The fan, flanges and silencing tube insert into a light, sturdy and moulded outer-body, deadening sound.
