Baghouse

A baghouse, also known as a baghouse filter, bag filter or fabric filter, is an air pollution control device and dust collector that removes particulates entrained in gas released from commercial and industrial processes. Power plants, steel mills, pharmaceutical producers, food manufacturers, chemical producers and other industrial companies commonly use baghouses to control emissions of air pollutants. Baghouses came into widespread use in the late 1970s after the invention of high-temperature fabrics capable of withstanding temperatures over 350 degrees Fahrenheit, and are highly effective, achieving collection efficiency rates of 99 percent or better, which often exceeds the performance of alternative pollution control technologies such as electrostatic precipitators.
