The filter box is designed to provide a compact and convenient clean air solution.
Factory assembled as a single unit, this fan eliminates the costly process of
designing, fabricating, and installing special remote filter box assemblies. Both
the fan and filter section feature removable access panels on both sides to
remove and replace filters, making fan maintenance simple and fast.
