PP Melt-blown Filter Cartridges

Name: PP Melt-blown Filter Cartridges
Brand: Xinnian
SKU: 1 / 5 / 10 / 25 μm

1 / 5 / 10 / 25 μm

PP melt-blown cartridges are formed from thermally bonded polypropylene microfibres in a gradient pore structure — loose outside, tight inside — giving high retention of suspended solids, rust and silt. Made entirely of PP with no binders and no fibre shedding, they are the most common economical cartridge for purifiers, pure water machines and industrial filtration.

Key Features

Gradient pore structure with high capacity and low pressure drop
All-PP construction, no adhesives, no fibre release
Acid and alkali resistant for a wide range of water
Economical for bulk replacement

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.
