Work out baghouse filter area instantly with clear inputs, formula shown and shareable results.
Filter area is gas flow per minute divided by the air-to-cloth ratio, which is the filtration velocity. Pulse-jet baghouses run 1.0-1.5 m3/m2/min, reverse-air 0.5-0.9 and shaker units 0.5-0.7. Exceeding the design ratio drives dust into the fabric, raising pressure drop and shortening bag life.
Filter area
Area (m2) = gas flow (m3/min) / air to cloth ratio
Bag count
Bags = ceil(area / (pi x bag diameter x bag length))
Particulate abatement performance is a permit condition. Filter design and bag selection must account for gas temperature, chemistry and moisture to avoid failure.
Higher pressure drop, dust penetration into the fabric, bag abrasion and blinding, and reduced collection efficiency. Bag life can fall from years to months.
Yes. Sizing must consider the ratio with one compartment isolated for maintenance, otherwise the remaining cloth is overloaded whenever a compartment is taken offline.
