Pilot Spinner industrial electrospinning system, front view, 60 kV

Electrospinning for filtration membranes

Electrospun membranes combine very small pore size with high porosity, so they capture fine particles while keeping airflow or flux high. That makes them ideal for air filtration, face masks, and water treatment.

Where it's used

  • Air filtration & HEPA-class media

    Nanofiber layers trap sub-micron particles at a low pressure drop.

  • Face masks & respiratory protection

    Lightweight, breathable media with high capture efficiency.

  • Water treatment & separation

    High-flux membranes for filtration and oil-water separation.

Frequently asked questions

Can electrospun membranes capture sub-micron particles?

Yes. Nanofiber diameter and packing capture very fine particles while keeping the pressure drop low.

Can I produce filter media at scale?

Yes. The Pilot Spinner and large drum collectors are designed for pilot and small-production volumes.
