Fabric Filters (Baghouses)

Fabric filters (also known as 'baghouses') are used to remove particulate from a gas stream. In order to increase bag life, maximize capture efficiency, and minimize pressure drop, it is desirable to ensure well-behaved flow through the device. Combining ICAC standards with manufacturer and final customer requirements, ASC can improve baghouse flows by:

Ensuring a uniform portion of the gas and particulate go to each baghouse compartment, with all compartments in service or with one out of service.
Ensuring that flows entering each baghouse compartment are well-behaved and that all bags are utilized within a given compartment.
Preventing gas velocities that are high enough to damage a bag
Minimizing pressure losses throughout the baghouse
