WEH^® Coalescing Filter

Dry gases, reliable systems

Efficient separation of liquid aerosols

In many gas applications, fine liquid droplets such as oil mist, water, or condensate enter the system – often unnoticed but with significant consequences: increased energy consumption, corrosion, and malfunctions. WEH^® Coalescing Filters reliably remove these aerosols – purely mechanically, without chemical additives. The result: dry, clean gases for long-lasting systems and precise processes.

Thanks to their compact design and high pressure resistance, the filters can be easily and space-efficiently integrated – ideal for dispensers, compressors, or storage units.

Your Benefits

Effective aerosol separation

Finest droplets adhere to fibers, coalesce, and are reliably separated.

Highly stable & robust

Pressure-resistant and suitable for high-pressure applications up to 450 bar – for demanding industrial uses.

Mechanical & chemical-free

Coalescence principle without additives – environmentally friendly and minimizes effort.

Easy maintenance

Safe condensate removal: Separated liquid collects in the housing base and can be drained in a controlled manner.

Optimized flow

Targeted slowing of the gas flow promotes droplet formation – for maximum separation efficiency.

Function of the Coalescing Filters

The pressurized gas flows into the filter inlet and passes through a multilayer filter element made of fine-fiber material. During this process, the finest liquid droplets and aerosols are mechanically separated and collected as condensate.

Separation principle overview:

Adhesion to fibers: Moist particles stick to the fiber material.
Coalescence: Small droplets merge to form larger droplets.
Gravity separation: The formed droplets settle into the filter housing and can be drained.
Additional solid particle separation: Dust, rust, or abrasion particles are also mechanically retained.

This keeps the gas clean and dry – and your system protected.

Typical application

Filtering media

Contaminants in the gas flow pose a risk to operational safety – even the smallest particles or liquid aerosols can cause failures. WEH® Filter Technology reliably protects your systems.
