The mechanism of fibre filters is well known and is basically a combination of impingement for particles greater than 1-2 microns in diameter and diffusion for the finer, particles when brownian motion becomes increasingly predominant. As the gas passes through the filter bed the small mist particles are bombarded by the gas molecules surrounding them, causing them to move in various direction, towards and away from the surface of the fibres making up the filters
Each filter is composed of millions of fibres and although the efficiency of each individual fibre is low the cumulative effect is very high. Low approach velocities are necessary in order to mask the diffusion velocities associated with brownian movement.
The candle are installed vertically and gases pass horizontally through the filter wall, the trapped particles coalescing and draining down through the filter bed.
With the innovative 2 Pack design CPL provides inexpensive solution to mist emission control problems. particle impingment & collection
Gas flow through candles can be either inside/outside or outside/inside depending upon the sitting of the installation and the method of securing the candles in place.
