Filtration Solutions
Start with the problem you are experiencing. We will help you diagnose the root cause, identify the right application approach, and recommend the products that solve it.
Service Life & Costs
Filter Element Life Too Short
Premature element replacement is the most common complaint in gas filtration. The root cause is rarely the element itself — it is almost always a system or specification issue.
Excessive Vacuum Pump Oil Consumption
If your vacuum pump is consuming more oil than it should, the exhaust is the first place to look. Unfiltered or poorly filtered exhaust carries oil aerosol that never returns to the sump.
Contamination & Purity
Oil Contamination in Compressed Air
Oil contamination in compressed air is one of the most widespread and underestimated quality problems in industrial facilities. The source is almost always the compressor — the solution is always multi-stage filtration.
Analyser Sample Contamination
When your gas chromatograph drifts, your CEMS reads high, or your moisture analyser gives erratic results, the problem is almost never the instrument — it is what reaches the instrument.
Moisture in Gas Systems
Water in any form — liquid, aerosol, or vapour — is the most common contaminant in compressed air and process gas systems. Left unmanaged, it corrodes pipework, damages instruments, and ruins products.
KOH & Electrolyte Aerosol in Hydrogen Gas
Alkaline electrolysers produce hydrogen saturated with KOH aerosol — a caustic mist that destroys everything it touches downstream. Removing it before the gas reaches dryers, compressors, or storage is not optional.
KOH Removal from Hydrogen Gas
Trace KOH aerosol in a hydrogen stream is removed effectively with borosilicate glass-microfibre coalescing elements for normal, moderate-temperature duty — that is our standard recommendation. Only under high caustic concentration, hot or saturated conditions do we switch the element media to PTFE or PP. In every case the housing is 316L with PTFE seals and a drainable sump.
Liquid Carryover & Slug Loading in Gas Filters
Coalescing elements are designed to remove aerosol — not to handle bulk liquid. When a slug of water, oil, or condensate hits a filter element, the consequences are immediate and expensive.
Compliance & Safety
Oil Mist in the Workspace
That thin oil film on every surface near your vacuum pumps? It is not just a nuisance — it represents airborne oil mist your operators are breathing. Most occupational exposure limits are well below what an unfiltered pump exhausts.
Emission Compliance
Environmental regulations for exhaust emissions are tightening across Europe. Whether it is TA Luft for stationary engines, EU Stage V for mobile machinery, or local port regulations — compliant exhaust filtration is no longer optional.
Special Conditions
Sour Gas and Corrosion
When hydrogen sulphide, carbon dioxide, or chloride ions are present in your process gas, standard carbon steel filtration equipment has a limited life expectancy. Corrosion does not give warnings — it causes failures.
High-Temperature Gas Filtration
Above 150 °C, standard aluminium housings, Buna-N seals, and adhesive-bonded elements start to fail. High-temperature gas filtration demands careful material selection across every component.
Explosive Decompression (RGD)
When high-pressure gas is depressurised rapidly, dissolved gas trapped inside elastomer seals expands violently — tearing the material apart from the inside. The result: catastrophic seal failure and uncontrolled gas release.
