Periodic bursts of compressed air clean dust collectors, or baghouses, at regular intervals by dislodging the particles, which fall to the bottom chamber for disposal or recovery. Moisture in the compressed air lines can have disastrous effects on baghouse operation. Properly treated compressed air brings many benefits, including increased cartridge life and replacement costs, less maintenance and downtime, increased overall dependability and productivity, improved air quality and increased product recovery. Steps for the proper selection of air dryers for dust collectors are recommended.
