The new ULTRA-PAC HEPA filters from Filtra Corp. feature the company`s CP pleating technology, which eliminates the need for the aluminum separators normally found in a standard 11.5-in. HEPA filter configuration.
The filters are manufactured in galvaneal steel frames using thermoplastic resin separators to give the lowest pressure drops at the highest air flows. They are available in two different pleat heights.
