WINDOW KIT WITH BACKDRAFT 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.
Only suitable with the Qik Series and QAX series
