Product Description

SPECTRUM SWP: 20-inch String Wound Polypropylene Sediment Filter

The SPECTRUM SWP 20-inch series provides high-capacity, depth-based particulate filtration designed for demanding water treatment environments. By utilizing a computer-controlled wound pattern, these filters achieve a graded-density structure, capturing larger debris on the exterior and finer particles deep within the media. This 20-inch configuration is the professional choice for systems requiring increased dirt-holding capacity, significantly extending time between maintenance compared to 10-inch alternatives. Ideal as a primary pre-filter for industrial processes, borehole water, and whole-house systems, the SWP range reliably protects pumps, valves, and expensive secondary filtration stages from fouling.

Why Choose the SPECTRUM 20" SWP?

  • Extended 20-inch Surface Area: The increased length provides double the filtration area of standard cartridges, maximizing dirt-holding capacity and reducing frequency of cartridge changeouts.

  • Graded-Density Depth Loading: Engineered to trap particles throughout the entire media depth rather than just on the surface, preventing pressure drops and ensuring consistent flow rates.

  • Broad Chemical Compatibility: Constructed from inert 100% polypropylene, making it suitable for manufacturing chemicals, metal finishing, and food-grade applications.

  • Wide-Span Micron Ratings: Available from 0.5 to 150 microns to perfectly match your specific sediment load, from high-turbidity well water to final-stage particle polishing.

The 20-inch filter provides double the surface area and dirt-holding capacity. If you find yourself changing your filters every few weeks, switching to a 20-inch SWP will significantly reduce your maintenance labour and overall operating costs.

Yes. The string wound construction is robust and ideal for the high-turbidity often found in borehole or well water. It acts as an excellent "first-line-of-defence" to remove sand and grit before water reaches your treatment system.
