The DFI-2000 Series joint requires no special framework for proper installation.

The integral flanges are bolted directly to the ductwork companion flanges by use of retaining bars. The need for additional gasketing is eliminated with the 2000 series due to the fact the molded, rubber, flexible joint is fastened directly to the existing
flanges.

The elimination of cumbersome, metal framework makes this series DFI-JOINT extremely easy to handle during installation.

The 2000 series DFI-JOINT is the only configurationoffered where there is absolutely no metal exposed to extremely corrosive gasses, such as encountered in scrubber applications. The fluroelastomers normally utilized in the construction of these joints not only provide excellent resistance to attack from acidic system flows but also eliminates the need for flow liners in most instances. This is due to the inherent resilience of the fluroelastomers used in the belt construction, which provide superior resistance to abrasive media encountered in all particulate laden flows. Only where extreme loading is expected should liners be utilized. Fly ash shields should be considered to assist the liners in preventing particulate from entering the expansion joint cavity.

This configuration DFI-2000 joint is also manufactured for high temperature applications and is so designated by a suffix "H" added to the base 2000 number (2000H).
