BHA Filter Bags & Cages

BHA Filter Bags

You will find we offer a complete range of fabric filter bags for your dust collection system in a wide variety of fabrics, finishes, styles and sizes. Because of the variety of particulates collected and individual operational conditions of collection systems, selection of replacement filters should be determined through careful analysis of your current operating parameters.

Filtration fabric should be selected for maximum filtration efficiency, dust cake release and durability. Operating conditions may include changes to gas stream chemistry, moisture or hydrocarbons, or high temperature spikes. All need to be considered to get maximum filter life and performance. The style and construction of bags are typically determined by the collector cleaning system and if support cages are needed.

Learn more about fabric characteristics and suitability referencing our Fact Sheet. The charts will specify the most popular styles, fabrics and finishes as well as the conditions each are best suited to handle.

We can deliver any type of filter bag for any OEM design or system application.

Check out our demonstration video for the proper way to easily install a snapband filter bag into a baghouse.

BHA Filter Cages

CLARCOR Industrial Air manufactures quality support cages for use in most baghouses. Properly designed cages serve as critical baghouse components for optimum bag performance and durability. Support cages are traditionally constructed of one of the following:
  • Low carbon steel (bright basic wire)
  • Galvanized low carbon steel
  • Type 304 stainless steel
  • Type 316 stainless steel
  • Hastelloy®
  • Other specialty materials

Hastelloy® is a registered trademark of Haynes International, Inc.

We offer specialty cage designs for specific applications.

Omni Cage
The Omni cage top was developed to facilitate snapband bag removal. It has a detachable top, which allows removal of the cage top first. With the cage top no longer blocking access to the snapband, the band can be snapped loose from the tubesheet, and the bag and cage body lifted out easily.

Two-Piece Cage
For applications with low headroom in the clean air plenum, CLARCOR Industrial Air offers a two-piece cage. This style can make for easier installation and removal in these difficult applications.

Chemically-Resistant Finishes
In addition to providing various stainless steel alternatives, we can provide PTFE and epoxy finishes to resist chemical attack.

Rigid Wire Cages

Standard and specialty cage tops are available and all bottom pans are welded to the inside. Options for rigid wire cages include:
  • 12 gauge wire diameter - .1055 in. (.27 cm)
  • 11 gauge wire diameter - .1205 in. (.31 cm)
  • 9 gauge wire diameter - .148 in. (.38 cm)
  • 7 gauge wire diameter - .177 in. (.45 cm)
  • 4 to 7.375 inch cage diameter (10.16 cm to 18.73 m)
  • Customized number of vertical wires (12 or 20)
  • Customized ring spacing - standard is 6 in. or 8 in. (15.24 cm or 20.32 cm)
