CECO Environmental products

Our Sethco filter tubes are fabricated of natural or synthetic fiber wound over a perforated plastic or metal core. The precision winding pattern covers the entire depth of the filter tube with hundreds of funnel shaped tunnels which become gradually finer from the outer surface to the center of the tube and trap progressively finer particles as the fluid travels to the center. This allows much greater solids retention capacity than is associated with surface filter media of the same dimensions.

Our Sethco brand Pleated Polypropylene Filter Cartridges feature an extended filter surface for greater dirt holding capacity compared to conventional cylinder, sleeve or wound type depth filter tubes.
