Stainless Steel Coalescing Filters for Gas and Vapor Pre-Treatment

Product overview

Our Coalescing Stainless Steel Wire Mesh Filters combine layered woven media and engineered surface finishes to separate liquid droplets and aerosols from gas streams efficiently. Unlike single-purpose particulate meshes, coalescer stacks capture fine mist, grow droplets by agglomeration, then drain them to collection ports — protecting downstream compressors, gas analyzers, membranes and safety systems. This product line is geared to upstream/downstream gas handling, compressed air systems, vapor recovery units and chemical process vents.

How it works
Multi-layer mesh packs (coarse support → transition → polishing layer) provide a progressive capture surface. Small droplets are captured on fine filaments, coalesce into larger droplets which migrate by gravity and shear to the element exterior where they are collected and drained. Hydrophobic or oleophilic surface finishes can be applied depending on whether the target phase is water or oil. Sintered bonding or welded seams ensure dimensional stability in pulsating flows and high ΔP scenarios.

Key advantages

• High coalescing efficiency: typical 0.3–50 μm capture with low initial ΔP when correctly staged.

• Reusable & cleanable: elements survive multiple backflush and solvent or steam CIP cycles—reducing TCO vs. disposable cartridges.

• Robust: stainless media tolerates elevated temperatures and aggressive chemistry; nickel alloys available for extreme service.
• Modular deployment: roll/blank supply for OEM conversion, pleated cartridges for compact housings, or framed pads for retrofit panels.

Maintenance & lifecycle
Routine inspection: pressure-drop trend, visual drain efficiency, and scheduled regeneration using recommended solvents or steam. We provide regeneration procedures and lifecycle forecasts to support procurement decisions.

Applications
Common uses include compressor inlet protection, membrane pre-treatment, vapor recovery unit (VRU) inlet protection, flue gas mist control, solvent condensate separation and refinery gas scrubber polishing. In compressed air systems they extend dryer and valve life by removing entrained liquids; in VRUs they reduce hydrocarbon carryover and downstream emissions.
