BioCel M-Pak filters offer the same media area as the traditional BioCel 12” -deep filter in a compact, lightweight design. Rated 95% efficiency on 0.3 µ m ( DOP) , the M-Pak also delivers comparable pressure drop and overall performance in a much smaller package. The BioCel M-Pak is designed to remove airborne biological contaminants in hospital critical areas and food and pharmaceutical processing plants. It is engineered to meet the exacting requirements of precision manufacturing operations and laboratories. BioCel M-Pak pleated media is made of high-efficiency, microglass paper with water repellent binder. Adhesive bead separators are applied in rows to both sides of the media. Adjacent separators bond to each other, forming a unitized, rigid media pack enclosed by a frame of high-impact polystryrene ( HIPS) plastic. The M-Pak’ s space-saving design reduces freight, storage, and handling costs. Constructed without metal components, it is fully incinerable. To maximize filter life, use BioCel M-Pak with high quality AAF prefilters.
