Oct 16, 2020· A central dust collector is designed to create a negative pressure at a dust source point and pull the fugitive material into the collector. Dust is filtered out of the air stream and dropped into the hopper off the unit so it can be placed back into the manufacturing process or disposed of properly.

Designing and Sizing Baghouse Dust Collection Systems

collector by calculating the total filter area of each filter (bag diameter x 3.14 x length ÷ 144 [for number of inches in a square foot] = filter cloth area) and then multiply that figure by the total number of bags in the collector. 3. Take the CFM of the system and divide it by the total filter cloth area to get your air to cloth ratio.
