Coalescing Filters & Mist Eliminators

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 industrial air filter systems to reduce the amount of mist, aerosols and fumes in the atmosphere. Often times, the mist pulled from the source will coalesce or unite into a hardened substance in the duct work and post a fire hazard.

Coalescing filters, commonly called mist eliminators are also needed to capture oil mist found in return air of industrial machine shops and water droplets from cooling coils and evaporative media or unevaporated moisture downstream from humidifiers.

Coalescing Mist Eliminator Filter Models

Permatron coalescing filters are available in two models, depending on your filtration needs:

Metal Mesh Oil or Water Mist Eliminator (Model MME) is constructed of multiple layers of metal mesh, expanded through specified feeds to assure maximum filtration and internal loading capabilities. The metal mesh media is supported within a 1″ or 2″ thick galvanized steel frame.
Synthetic Mist Eliminator (Model SME) is designed to utilize the natural affinity between plastics being processed and the plastics used in some of the washable media filter. Model SME filter has a stainless steel frame and contains variable layers of honeycombed, corrugated and tubular monofilament polypropylene media sandwiched between two structural outside panels, offering a significant surface area within the air filter for coalescing to occur.

Tested in ope coalescing air filters from Permatron ration, Permatron’s synthetic coalescing air filter yielded 2.5 lbs. of “gunk” in eight hours and kept duct work free of buildup.

Coalescing or Mist Elimator air filters can be custom designed and sized to fit any application specifications. Wash with soap and water as needed. Model MME and Model SME both carry a 5 year warranty.

The distributor you got me in contact with sent me the three PreVent Model R filters I was looking for. They are working great. Thank You.

Everything was correct & professionally served, finely crafted with accurate dimensions of quality material. I will purchase further metal mesh filters from your firm in the future as demand calls for.

We had to change a combined condensing / free cooling coil because it was so badly damaged from debris and washing. 10k€ (approx. $12,000 USD) for the coil and works and 6k€ (approx. $7000 USD) for the crane hire. The second chiller on the site is perfect as the screen was fitted back some time ago.

The filters we purchased are a great addition to our plant operations. I am looking at other applications for their use…

The order process went very well. We received the black washable fan bonnets 2 weeks ago and are very happy. I will order again in the future. Great product and great service. Thank You!

It’s always a great idea to protect HVAC condenser coils with screening, especially if you can do it right after new equipment installation. Once the magnets where inserted into the screen grommets, it took literally less than a minute to place the screening on the equipment, adjust it, done. This screening will protect the condenser coils from grass cutting, bugs, cottonwood seedlings, etc.

The guys love them! Clean look, and easy to clean….

Our customer, Logoplaste, uses and raves about the Prevent BHA Screens and MagnaMount Kits.We did an install at their manufacturing facility in June on two units, all four sides required screens. Installation time was drastically reduced from the original 6 hour estimate with standard mount clips, to complete screen installation in under 1 hour with MagnaMount clips.The facility is located along the river where cottonwood trees are very abundant. Even when installing PreVent, it was catching the cottonwood that was flying. I brought him out one of your cleaning brooms a week after install, and the Maintenance Manager said that it is the best money he has spent since he has worked at that facility. He is planning on purchasing some more for his 4 Cooling Towers as well.

The PreVent bonnet style filter is the best thing I have ever bought to protect our cooling tower circular fan. We have to clean it every two weeks but it is so easy.
Martyn RogersCotek Papers Limited, Maintenance Manager
Permatron's PreVent screening was installed on recently replaced 363A RTU condenser coils, outside air and economizer openings, using MagnaMount magnets to hold them in place VS drilling and screwing them on. The magnets will most definitely be our primary mounting option going forward. All three screens took us literally less than five minutes to install. I noticed how quickly cottonwood was caught by the screening.The screens can be cleaned in place or easy removed for more detailed cleaning.
