Coalescing Fiberbed Mist Collectors (AIRCLEAR™)
Coalescing Fiberbed Mist Collector Systems capture, collect, and remove the liquid mists, aerosols, and sub-micron particles, that cause opacity, smoke, and blue haze. Coalescing Fiberbed technology eliminates aerosol mists and submicron particles from virtually any gas stream.
Air Clear’s Coalescing Fiberbed Mist Collector Systems use the field-proven processes of Impaction, Interception, and Brownian Diffusion: Impaction occurs when particles in the <4 micron range is carried via inertia until they strike a filter fiber and are collected. Interception occurs when microns (1-3 range) possess less momentum and typically follow the air stream until they deviate and graze the side of a filter fiber, removing them from the air stream. Brownian Diffusion is sub-micron particles (<1 micron) that contain very little mass and follow the air stream. As the air cools, random movement of particles slow down as they collide and coalesce until increasing in size enough to be filtered via impaction/interception. Air Clear Fiberbed Mist Collectors work to eliminate opacity and other industrial air pollution problems.
Air Clear Coalescing Fiberbed Mist Collectors are custom designed for many Industrial Processes
Air Clear’s Coalescing Fiberbed Mist Collectors is proven Technology that offers a cost effective solution for the control of opacity and odors … Here’s why…
Low capital cost when compared to other technologies.
Air Clear’s Coalescing Fiberbed Mist Collector Systems save customers money with its low operating costs
- Low initial pressure drop saves energy
- Fan motor runs on VFD to minimize power usage
- Long filter life means low replacement cost
- Collected liquids are often recycled saving material costs
- Low maintenance cost
Superior Filter Performance
- Air Clear Coalescing Fiberbed Mist Collectors are guaranteed to reduce stack opacity to 5% or less, excluding steam and uncondensed materials (see cooling for a discussion of this subject generally they achieve near zero opacity.
- Air Clear Coalescing Fiberbed Mist Collectors also offer very high particulate removal efficiency, in excess of 99%. They exceed the proposed OSHA requirement of 0.5 mg/m3 for indoor coolant/oil mist, and so are ideal for bringing Indoor Air Quality such as in, metalwork facilities into compliance.
- Air Clear Coalescing Fiberbed Mist Collectors are subjected to rigorous testing to ensure design level field performance. This testing is the most stringent in the industry. Test conditions are more demanding than most field conditions. Our customers are welcome to witness this testing in our shop.
- When tars, stone dust, talc, etc are present an Air Clear indexing prefilter is recommended to extend the life of the main filters.
- Typically, the equipment is totally assembled for verification of fit of components. Shop assembly and testing allow Air Clear Engineers to verify performance prior to shipment. Any non-conformity is corrected before installation at the customer’s site.
- The fiberbed filters themselves are subject to a performance test procedure which checks the opacity control and pressure drop levels are within Air-Clear’s design parameters.
- Benefits to the customer are:
- Faster, trouble free installation reduces installation costs
- Less downtime, increased revenue from production
- Higher on-line reliability from day number one
- Our customers are encouraged to witness the shop testing . This is often an excellent opportunity for our customers to receive training on the equipment.This allows for the customer’s personnel to become comfortable and knowledgeable with the equipment before it is even shipped! and testing of systems. All Air Clear Systems are designed, manufactured, assembled and tested prior to shipment to ensure trouble-free installation and start-up.

The Importance of Cooling The Process Air Temperature
- Filters will not collect vapor phase molecules and particulate.
- Vapors must be cooled to between 120°F -150°F to condense most materials before entering filter for maximum efficiency. The cooler the exhaust, the more efficient the filter is.
- CYCLONIC SCRUBBER
For many applications such as asphalt coaters, saturators, textile tenter frames where the exhaust temperature is as high as 400°F adiabatic (water evaporation) cooling is used to lower the exhaust temperature. The bottom of the filter tank becomes the holding tank of the recycled water. The water is distributed over the Cyclonic tray which in addition to mixing the hot air and water it helps remove(scrub) solids from the exhaust.
- AIR DILUTION COOLING
Dilution with ambient air controlled by a damper, or a temperature controller and actuated damper.
- AIR-TO-AIR HEAT EXCHANGERS
Clean ambient air on one side of the air-to-air heat exchanger used to cool the hot process exhaust passing along other side of air-to-air heat exchanger.
- COOLING COILS
Finned or smooth water cooling coils allow heat exhaust to pass outside the finned tube while cool water flows through it. The exhaust is cooled by transferring heat to the cooling water indirectly-without direct contact.
