Efficient separation of liquid aerosols
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.
Effective aerosol separation
Finest droplets adhere to fibers, coalesce, and are reliably separated.
Mechanical & chemical-free
Coalescence principle without additives – environmentally friendly and minimizes effort.
Optimized flow
Targeted slowing of the gas flow promotes droplet formation – for maximum separation efficiency.
Highly stable & robust
Pressure-resistant and suitable for high-pressure applications up to 450 bar – for demanding industrial uses.
Easy maintenance
Safe condensate removal: Separated liquid collects in the housing base and can be drained in a controlled manner.
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.
