Coalescing Air Filter




Smoke and fumes are sub-micron particulate by-products created by manufacturing processes such as welding, rubber and plastic processing, high speed machining with coolants, tempering, and quenching.

Assembly lines are equipped with source capture filtration systems to reduce the amount of mist, aerosols and fumes in the atmosphere. The mist pulled from the source will coalesce or unite into a hardened substance in the ductwork and post a fire hazard.

Permatron has designed a custom coalescing filter utilizing the natural affinity between plastics being processed and the plastics used in some of the washable media filter.

The filter has a stainless steel frame and contains variable layers of media inside. Sandwiched between two structural outside panels are multiple layers of honeycombed, corrugated and tubular monofilament polypropylene. This offers a significant surface area within the filter for coalescing to occur.

Tested in operation, the filter yielded 2.5 lbs. of "gunk" in eight hours and kept ductwork free of buildup. Filter can be washed with soap and water as needed.

Coalescing filters can be custom designed and sized to fit any application specifications and are available in the UK from RAB Specialist Engineers Limited.
