WKS – Window Kit Shutter
- The WKS is a window kit designed to be used when installing a fan in the window.
- This includes an external grille with gravity shutters that is made from impact and UV resistant RAL9010.
- It is recommended to be used in combination with fans that don’t have shutters.
- The shutters open automatically when the air flows through the unit.
- When the fan is off they close down so to prevent air and insects entering from outside.
