Refilter manufactures products from Permeable Wire Material (PWM) — a unique stainless-steel-based structure that combines mechanical strength with controlled permeability.
What is WPM?
It’s an oriented wire system, formed by cold pressing into an open porous structure.
This material performs multiple functions at once — as a:
– filter
– seal
– damper
– heat conductor
All while remaining elastic and resistant to aggressive environments.

Permeable Wire Structures by Refilter — Built for Extreme Conditions
Refilter’s Permeable Wire Material (PWM) performs where others fail — from deep underground wells to pharmaceutical production. Our technology is based on the Koerberle effect: filtration occurs not only on the surface, but through the volume of the material, where a natural gravel-barrier-like pre-filter forms. We design and manufacture high-performance components for a wide range of industries, including:
- Filters
- High-pressure seals
- Heat pipes
- Dispersers
- Flameless burners
- Silencers
- Separators
- Soot catalysts
- Vibration damping units
