Products Description
Wound filter cartridges consist of a continuous yarn or fiber spirally wound around a central core. By varying the yarn thickness and winding density, a gradient of pore size can be created from the outer layer inward. As a result, contaminants are intercepted in stages-first coarse debris, then finer particles-minimizing pathways and maximizing throughput.

features
✅ High Contaminant Capture
Multi-layer, gradient-density winding maximizes dirt-holding capacity and prevents premature clogging.
✅ Stable Flow & Low ΔP
Precision winding delivers uniform flow distribution, reducing pressure drop and energy costs.
✅ Chemical Compatibility
Available in polypropylene, polyester, or glass-fiber options for broad chemical resistance.
✅ Customizable Lengths & Micron Ratings
Tailor-to-order sizes (4.75″–40″) and ratings (0.5–150 µm) to suit exact process requirements.
Applications
- Heavy Particulate Loads: Coolant recycling, mining slurry pretreatment, RO protectors.
- High-Viscosity Fluids: Syrups, resins, lubricants (minimal pressure drop buildup).
- Aggressive Chemistry: Solvent recovery, acid baths (PP/GFF compatible with pH 0–14).
Success Story: A Canadian oil sands operator cut filter spend by 52% using our 50 μm glass fiber wound filter cartridges for produced water.
