Motorized inlet shutter

Motorized inlet ShutterVostermans Ventilation puts an inlet shutter on the market for agricultural and industrial applications. This motorized inlet shutter causes air to enter the room in a controlled way. In fully open position a relatively large amount of air, in comparison to traditional air intake systems, will flow into the room. However, in closed position the shutter lets almost no air and light through. Because the motor is mounted on the inside of the shutter, the installation is easy. The double bearing suspension of the louvers ensures a long life.
