Answers to 10 common questions about bag filters
Bag filters are the lungs of a baghouse dust collector. Selecting the right bag filter for your pulse-jet baghouse can help you improve your filtering efficiency. As part of Powder and Bulk Engineering's continuing question-and-answer series on common powder and bulk solids handling problems, a materials handling specialist answers 10 common questions about bag filters.
Q: What is the air-to-cloth ratio and what should I know about it? A: The air-to-cloth ratio is the volume of air [in actual cubic feet per minute] flowing through the dust collector's inlet duct divided by the total square feet of cloth area in the bag filters. Achieving the correct air-to-cloth ratio involves determining the right number of bag filters [since they're typically a standard size] for the air volume flowing through your pulse-jet baghouse.
