Brownian motion media consists of a thick fiber mesh made from ultra-fine glass or polypropylene fibers. The media is packed between reinforcing screens for strength and can vary in thickness from one to several inches. Depending on the application requirements, the fiber diameter, mesh density and thickness can be varied to achieve very high removal efficiencies.
Configured into large “candles” or square columns, this design lends itself to high volume, low velocity applications such as blowers. This design is best used for mist elimination in highly corrosive services or applications where the gas is relatively free of solids. It is not recommended for general compressor suction protection due to its relative large size and difficult maintenance. Figure P-14 illustrates a Brownian motion high efficiency mist eliminator.
