Process Filters

When your air carries oil mist, VOCs, chemical fumes, or compressed-air contamination, a standard dust filter blinds in weeks. You need media matched to what you’re actually pulling — built custom or quick-shipped to your specs.

The Problem

Why a Standard Filter Won’t Hold Up

Oil mist overload

Saturates and clogs general-purpose media in weeks, driving pressure drop and downtime.

VOC & chemical attack

Solvent vapors and acids break down standard filter media that was never rated for them.

Moisture & blinding

Condensate blinds the filter face and invites bacterial growth in the housing.

Specs that don’t match

A filter chosen by size alone — not by your contaminant — rarely meets the standard your process answers to.

Be Honest With Yourself

When a Process Filter Isn’t What You Need

We’d rather steer you to the right thing than sell you a custom build you don’t need. A process filter is the wrong call if:

Your air is dry particulate, not mist or vapor. Wood sanding dust, weld fume, grinding fines — those belong on a cartridge or baghouse collector, not a coalescing or carbon filter. Different problem, different equipment.

You just need routine replacement elements. If you already run the right housing and only need cartridges on a schedule, a standard catalog filter does the job — no custom vessel required.

You don’t know your contaminant or flow yet. Picking media before you’ve characterized the stream is how facilities end up filtering the wrong thing. Start with the audit, then the filter.

If you’re dealing with mist, VOCs, chemical fumes, or compressed-air contamination and need media that actually matches it — that’s exactly the build we do.

Questions Buyers Ask

Process Filter FAQ

Why does oil mist clog a standard filter so fast?
Aerosolized oil and coolant coat standard media and don’t drain off, so the filter saturates and pressure drop climbs within weeks. A coalescing filter is built to merge those fine droplets and drain them away, which keeps the element working and the oil out of your recirculated air.
Which filter removes VOCs and odors?
Activated carbon. Particulate filters capture solids but pass vapor straight through; carbon adsorbs VOCs, odors, and hydrogen sulfide. The carbon type and bed depth are matched to your specific compounds and concentration.
What compressed-air filtration do I need?
Compressed-air cleanliness is defined by ISO 8573-1, which sets classes for oil, water, and particulate. Most critical applications target Class 1 for oil and particle removal. The right stage depends on what the air feeds — pneumatics, coatings, instrumentation, or food and pharma contact.
Can you build filters for acid mist and aggressive chemicals?
Yes. Chemical-resistant builds use PTFE or PVDF media and stainless housings rated for the acids or solvents in your stream, so the filter itself isn’t degraded by what it’s capturing.
Do you make custom housings, or only standard sizes?
Both. When a standard housing fits your flow and connections, that’s the fastest, lowest-cost route. When it doesn’t, we build a custom vessel and element set to your exact flow rate, port configuration, and footprint.
What documentation comes with a process filter?
Test reports and material certifications with every build, plus guidance on the standard your process answers to — OSHA 1910.1000 for chemical exposure, EPA VOC limits, or FDA 21 CFR 211.72 for pharmaceutical air, depending on the application.
