Wound Filter Cartridges

Name: Wound Filter Cartridges
Brand: Xinnian
SKU: 10 / 20 / 30 / 40 inch

10 / 20 / 30 / 40 inch

Wound cartridges are made by winding polypropylene yarn in a set pattern over a perforated core, forming a depth filter that is coarse outside and fine inside. They hold a lot of dirt, withstand pressure and can be washed and reused. Common duties include plating, surface treatment, coating and pre-filtration for water equipment.

Key Features

Depth gradient structure with high dirt holding capacity
Polypropylene media resistant to acids and alkalis
Tight construction that resists deformation under pressure
Washable and reusable for low running cost

Frequently asked questions

Which micron rating do I need?

5 µm for RO pre-filtration, 1–10 µm for polishing, 0.2–0.45 µm pleated for sterile filtration.

Pleated, wound or melt-blown?

Pleated gives the highest dirt holding capacity per cartridge; wound is economical for coarse filtration; melt-blown suits high-flow pre-filtration.

What is the maximum operating temperature?

PP cartridges 60 °C, PTFE/glass fibre pleated up to 120 °C; do not exceed differential pressure of 0.2 MPa.
