Maximum Filtration Area in Minimum Space for Industrial Dust Collectors

Skytech Ultrafab Pleated Cartridge Filters provide extended surface area dry air and gas filtration for dust collectors, HVAC pre-filters, and industrial air purification systems. The pleated design accommodates significantly greater media surface area than conventional cylindrical bags of the same diameter, resulting in lower energy consumption, reduced pressure drop, and extended filter life. Available in cellulose, polyester, polypropylene, and membrane-laminated media with OD/ID and length to fit all standard dust collector configurations.

What Are Pleated Cartridge Filters?

Pleated cartridge filters are cylindrical or conical filter elements in which the filter media is folded into a series of parallel pleats and bonded to end caps to form a rigid, self-supporting element. The pleating dramatically increases the available filtration area compared to a flat or felt tube of the same outer diameter — typically by a factor of 5 to 10 — enabling higher airflow, lower pressure drop, and longer service intervals in the same dust collector housing footprint.

Features and Benefits

• High Surface Area: Pleated construction delivers 5–10× greater filtration area than an equivalent-diameter felt bag — lowering air-to-cloth ratio and extending service life significantly
• Low Pressure Drop: Greater media area means lower face velocity through the media surface, reducing pressure drop and fan energy consumption throughout the filter service life
• PTFE Membrane Option: ePTFE membrane lamination on the media surface provides surface filtration for fine, cohesive, and hygroscopic dusts — enabling efficient pulse-jet cleaning even with difficult dust types
• Rigid Self-Supporting Structure: Polyurethane or hot-melt end caps with inner support core maintain cartridge geometry under pulse-jet cleaning loads — no cage required in most designs
• Multiple Media Options: Cellulose, cellulose-polyester blend, spunbond polyester, and ePTFE membrane media grades to suit ambient, moderate temperature, and chemically active dust collection applications
• Universal End Fitting Options: Open/closed top, flat top, fin-seal top, and custom flange configurations to fit all major dust collector OEM tube sheets and cartridge housings
