Dust collection efficiency of filters

A commonly overlooked area of inefficient compressed air use is dust collector pulse-jet cleaning — either bag (sock) type, or reverse flow filter type. Dust collector systems are vital to many plant operations, particularly with respect to meeting both indoor and outdoor air quality standards. They are also often used to collect income-producing product

Why does filter efficiency constantly change in a dust collector? As a dust collector runs, dust loads onto the filters and forms a dust cake. This dust cake resists airflow across the filter media. The resistance is measured in water gauge or pascals and is referred to as pressure drop. It is usually below 1” of water with clean filters. As dust loads and pressure increases, the

The goal of a dust collector is to control emissions over time. Upon first glance, it would appear that a filter’s efficiency would be directly related to the emissions that the filter allows to escape the system. However, a filter’s efficiency cannot be directly correlated with emissions in an industrial dust collector
