WEH® Filter Technology
Reliable protection for your systems
Why filters are indispensable
In technical systems, even the smallest contaminants pose a risk: they lead to premature wear, impair functionality, and in the worst case, jeopardize the entire system. Filters are therefore essential to ensure long-term protection of components and reliable system operation. WEH® Filters help maximize system availability and minimize downtime – for greater efficiency, safety, and durability.
Clean systems. Safe processes.
WEH® Filters offer more than just reliable media purification – they are the result of advanced engineering, intelligent design, high-quality materials, and decades of experience. Our portfolio covers a wide range of requirements – from simple protective filters to highly specialized solutions for critical applications.

Efficient media filtration
Effective separation of solids and liquid components – mechanical, reliable, and with filtration fineness ranging from 10 to 50 microns.

Compact & flexibly integrable
Designs available as inline or T-type versions – suitable for any system configuration.

Low maintenance & reusable
Wire-wound filter elements can be cleaned and reused – saving both material and time.

Customizable & project-specific
Standard products or customized filter solutions – depending on the application. We develop according to your requirements.

High pressure ranges
Solutions for applications up to 490 bar operating pressure – made of stainless steel or special alloys.

Particle Filter
For pure gases and protected components: Reliably remove solid impurities such as rust, abrasion or welding beads from the gas flow. They effectively protect downstream components from wear and increase operational safety.

Coalescing Filter
For dry, clean gas flows: Liquid aerosols such as oil, water, or condensate have no place in sensitive gas applications. Coalescence filters reliably remove them – purely mechanically, without chemical additives.
