ELTA TRADE WKS Window Kit with Backdraft Shutter (4″, 5″, 6″) For Qik / QAX Series

The ELTA TRADE WKS is a specially designed window kit with backdraft shutter for use when installing a fan directly in a window opening (instead of wall/duct). It includes an external grille fitted with gravity-operated shutters that open when the fan is running and close when off, helping to block outside air, dust and insects from entering through the window slot. The kit is impact- and UV-resistant, finished in RAL9010 white, and only suitable for use with Qik and QAX series fans.
