What it is and when to use it

The NWPL folding filter cartridge is a deep-layer filter made from folded ultra-fine polypropylene fibre membrane, rated from 0.1 to 30 micron. Use it where you need high throughput at fine ratings, such as electronics high-purity water, pharmaceutical infusion filtration and organic solvent filtration.

Folding the ultra-fine polypropylene membrane creates a large filtration area inside a standard cartridge format, so the cartridge can remove micro-particles while keeping flow high and pressure drop low.

The NWPL catalogue lists typical duties: high-purity water filtration in electronics, removal of micro-particles and infusion filtration in pharmaceuticals, organic solution filtration in chemical plants, and filtration in the petroleum industry. The 0.1–30 micron range lets one cartridge family cover everything from general polishing to very fine filtration. Protect it with a depth pre-filter when solids loads are significant.

Use it for

  • High-purity water filtration in electronics manufacturing
  • Pharmaceutical micro-particle removal and infusion filtration
  • Organic solvent and chemical solution filtration
  • Fine final filtration at high flow rates

How to choose

  1. Choose the micron rating from 0.1 to 30 to match the particle size you need to remove
  2. Confirm the compatibility of polypropylene with solvents and process temperature
  3. Match cartridge length, diameter and end fittings to the housing
  4. Use a spun or wire-wound pre-filter to protect the fine membrane
  5. Validate performance with a trial for pharmaceutical or electronics duties

Frequently asked questions

What micron range does the NWPL folding filter cartridge cover?

The NWPL folding cartridge is rated from 0.1 to 30 micron. The finest grades are used for high-purity and pharmaceutical duties, while coarser grades handle general polishing. Because the membrane is folded, the cartridge has a large filtration area, which keeps flow high even at fine ratings.

Is the folding cartridge suitable for organic solvents?

The NWPL catalogue lists organic solution filtration in the chemical industry as a typical use, and polypropylene resists many solvents. Compatibility still depends on the specific solvent, concentration and temperature, so share those details with us before specifying the cartridge.

How is a folding cartridge different from a PP spun cartridge?

A PP spun cartridge is a thick, gradient-density depth filter that holds plenty of dirt at coarser ratings. A folding cartridge uses a thin, ultra-fine membrane folded to give a large area, reaching finer ratings down to 0.1 micron with higher throughput. Spun cartridges often protect folding cartridges as a pre-filter.
