‘Becofil’ Candle Demisters

- 'Becofil' Candle Demisters, commonly referred to as Candle Filters - are intended primarily for the removal of very fine mist particles of less than 2 microns. A combination of impingement for removing greater than 1-2 microns and diffusion for finer particles where Brownian motion becomes increasingly predominant. - Each filter is composed of millions of fibres, and although the efficiency of each individual fiber is low, the cumulative effect is very high. Low approach velocities are necessary in order not to mask the diffusion velocities associated with Brownian movement. Candle filters are installed vertically and gases pass horizontally through the filter wall, the trapped particles coalescing and draining through the filter bed.
