Rigid Bag Filters are a high efficiency compact filter with a high media surface resulting in low resistance and high dust holding capacity. The core of the filter is a pleated filter media with thermoplastic separators to form a pack that is sealed in a plastic frame in a V formation. Rigid Bags come in three standard sizes with 20 or 25mm headers.
Rigid Bag Filters are usually found in supply air systems, but sometimes in extract system in kitchens / restuarants.
