FHD Plug Fan Assemblies

Air Dam - Fiber Shaft Seal

This is the standard sealing arrangement. Multiple ceramic fiber gaskets are sandwiched between retainers. The gaskets are cut to be a snug fit around the fan shaft. This method of sealing is not gas tight. The air dam blocks radiant heat from the fan exterior components as well as reducing air leakage into or out of the furnace / oven.
