Economical String Wound Cartridges for Sediment Removal

Skytech Ultrafab Wound Filter Cartridges are precision-wound polypropylene, cotton, or glass fibre yarn filters providing graded-density depth filtration for sediment removal in drinking water, irrigation, industrial process water, coolants, and general chemicals. With a continuous diamond winding pattern that creates progressively finer porosity from outside to centre, they provide high dirt-holding capacity at an economical cost.

What Are Wound Filter Cartridges?

Wound cartridges are produced by wrapping yarn in a diamond (rhombic) pattern around a central core — typically polypropylene or stainless steel. The winding tension, yarn count, and inter-layer spacing create a graded depth structure where the aperture between yarn strands decreases progressively from the outer to the inner surface.

Features and Benefits

• Graded Depth Filtration: Diamond winding pattern creates progressively finer porosity toward the core, maximising dirt-holding capacity and filter life
• Multiple Yarn Materials: Polypropylene yarn for chemical resistance; cotton yarn for higher temperature and natural fibre preference; glass fibre for special applications
• Wide Micron Range: Available from 1 µm to 150 µm nominal for pre-filtration and primary filtration applications
• Core Options: Polypropylene core for chemical service; stainless steel core for steam cleaning and high-temperature applications
• Universal End Fittings: DOE, SOE-flat, and SOE-222/226 bayonet fittings fit all standard 10-inch to 40-inch cartridge filter housings
• Most Economical Cartridge: String wound cartridges are the lowest cost per unit volume of filtration among all cartridge types — ideal for high-flow pre-filtration

Applications

• Drinking Water: First-stage sediment cartridge in household and industrial point-of-use water filtration systems
• Irrigation Water: Drip and sprinkler irrigation system pre-filtration to protect nozzles and emitters from sand and grit blockage
• Cooling Towers: Cooling water make-up filtration to control suspended solids in open recirculating cooling systems
• Industrial Coolants: Metalworking coolant pre-filtration to extend coolant service life and protect machine spindles
• Chemical Compatibility: PP yarn provides excellent compatibility with acids, alkalis, and aqueous chemical solutions
