Fabric Selection

Because each baghouse has its own set of characteristics and system parameters, it is important to evaluate each of the following variables in order to choose a fabric best suited to the system:

  • Temperature
  • Moisture level
  • Particulate size
  • Gas stream chemistry
  • Air-to-cloth ratio
  • Particulate abrasiveness
  • Mechanical factors, such as cleaning style, installation, etc.

In general, felt filter bags are used in pulse-jet collectors. Woven filter bags are used in reverse air or shaker baghouses.

We offer a number of specialty fabrics that collect particulate with the dustcake and fabric structure.

Tri-Loft and Reverse Air Tri-loft fiberglass were developed with highly texturized bulky yarns on the filtration surface to add surface area, depth and felt-like density to provide maximum efficiency, high airflow capabilities and excellent durability. These fabrics feature the Blue Max-CRF/70 chemically resistant finish, providing state-of-the-art fiberglass encapsulation. Tri-Loft is widely used in incinerators, coal- and waste-fired boilers, cement kiln and carbon black applications.

Duo-Density felt fabrics are for pulse-jet and reverse air dust collectors. These fabrics feature a blend of finer denier fibers on the filtration surface to provide a tighter surface for filtration without increasing differential pressure. The surface fibers maximize collection efficiency while allowing the bag to clean down properly and regenerate its permeability. The heavy-duty scrim of the duo-density fabric provides dimensional stability to help maintain proper bag tension and cleaning efficiency in structural reverse air baghouses.
