Even the smallest contaminants in technical systems pose a risk: They lead to premature wear, impair functionality, and in the worst case, endanger the entire system. Filters are therefore essential to protect components in the long term and ensure the reliable operation of systems. WEH® filters help maximize system availability and minimize downtime - for greater efficiency, safety, and durability. WEH® filters help to maximize system availability and minimize downtimes - for greater efficiency, safety and longevity. THE POSSIBILITIES OF WEH® FILTER TECHNOLOGY WEH® filters offer more than just...

WEH® particle filters for pure gases and reliable components The smallest solids in the gas flow - metal abrasion, rust, dust, sealing residues - are frequent causes of problems in high-pressure systems. WEH® particle filters consistently eliminate these risks and protect downstream components such as valves, regulators and sensors. This keeps sensitive components clean for safe processes and long-lasting systems. Function of the particle filters The pressurized gas flows into the filter inlet and passes through a fine filter element. Impurities are separated by various physical effects: Î Î...

General information WEH® coalescing filter for dry, clean gases In many gas applications, fine liquid aerosols - such as condensate, oil or lubricants - enter the system. These increase the flow resistance, increase energy consumption and can damage components. WEH® coalescence filters reliably remove these aerosols - purely mechanically and without chemical additives. Function of the coalescence filter The pressurized gas flows into the filter inlet and passes through a multi-layer filter element made of fine-fibre material. Meanwhile, the finest liquid droplets and aerosols are mechanically...

Filter solutions for technical gases & industrial applications Reliable filtration for clean processes and consistent gas quality In industrial gas applications, the purity of the medium determines the safety, quality and service life of the entire system. Residues from cylinders, pipelines or pressure reducers - such as abrasion, oil, rust or moisture - can disrupt processes, damage devices or have a negative impact on product quality. WEH® filter solutions ensure clean, dry gases - directly at the point of use or in the central gas supply. They protect downstream components, ensure consistent...
