Bachmann Dampjoint designs and manufactures a multitude of different types of gas flow dampers in all sizes and configurations. Found in heavy utility and industrial plants, Bachmann Dampjoint gas flow dampers, with many cost effective innovations, are used for isolation, flow control or a combination of both. The blades are actuated by pneumatic, electro-mechanical, hydraulic, or manual drive systems.

Our long history of supplying equipment to a wide array of industries has resulted in a strong ability to offer dampers with a variety of special, custom-designed features to address challenging applications, such as:

CORROSIVE FLUE GAS:

  • Nickel alloy construction
  • Corrosion resistant alloy cladding/wallpapering
  • Glass flake/resin lining
  • Heat tracing
  • Composite materials

HIGH TEMPERATURE:

  • Refractory lining (castable and fibre)
  • Water and air cooled blades & frames
  • High temperature alloy construction
  • Thermal compensating drive systems
  • Heat shields & heat breaks

ABRASIVE MEDIA:

  • AR steel construction
  • Easily replaceable components
  • Carbide flame coating

HIGH DUST/ASH LOAD:

  • Integrated ash hoppers
  • Oversized drive components
  • Optimized damper location/orientation
  • Specialized seal designs

On numerous occasions, Bachmann Dampjoint has custom designed and manufactured specialty dampers that are outside of the conventional damper categories.

Offset Disk Dampers

Offset Disk Dampers

Also known as 3-lever valves, the offset disc damper is used where the degree of tight shut-off required cannot be achieved with a butterfly damper, and where a guillotine damper is not practical.

Dual Seal Dual Skin (DSDS) & Double Louver

Dual Seal Dual Skin (DSDS) & Double Louver

Our DSDS design is the best technical and commercial fit for isolation applications where the damper is normally open, and reliability is a concern. The innovative DSDS design is our cost effective dual-louver solution.

Louver and Butterfly Dampers

Louver and Butterfly Dampers

Combining efficient seating and rugged design, butterfly and louver dampers are capable of 99.9% shut-off in certain applications. Flexible stainless steel or nickel alloy seals assure long-life and easy maintenance.

Guillotine Solid – Flex & Convolution Seal

Guillotine Solid – Flex & Convolution Seal

When tight shut-off is paramount, a guillotine is often specified to do the task. However, there are many different designs and the selection of the proper type of guillotine damper depends on the application and can vary greatly.
