Cotton Wound Filter Cartridge

 

Robust cotton wound filter cartridges deliver exceptional depth filtration through precision-wound 100% pure cotton yarn. Engineered for high dirt-holding capacity and consistent flow rates, these cartridges mechanically trap particles across their gradient density structure. Ideal for viscous fluids, aggressive chemicals, and processes requiring cost-effective, sustainable filtration.

✅ Depth‑Loading Efficiency

Gradient winding captures large contaminants on the outer layers and finer particles deeper within, maximizing dirt‑holding capacity.

 

✅ Chemical and Thermal Resistance

Resistant to acids, bases, and hydrocarbons (≤121°C/250°F)-outperforms synthetics.

 

✅ Sustainable & Food-Safe

FDA-compliant 100% natural cotton; biodegradable and non-shedding.

 

✅ Low ΔP & High Flow

Optimized filament orientation ensures minimal pressure decline even at high flow rates.

 

✅ Universal Compatibility

Standard 226/flat end caps and multiple length options fit all common housings.
