RSK-200 Back draft damper

Fantech’s most popular accessory, the backdraft damper, prevents unwanted air from entering through supply/exhaust ports.

Using a backdraft damper will ensure that air can only flow one way. For the residential setting, this can help the homeowner keep the intended pressure scheme intact. All-in-all, this product makes it harder for non-conditioned, outdoor air to enter the living space through cracks or leaks in the home. This further protects individuals from outdoor pollutants and the reentry of unwanted air.
