Highly flexible product range
Offers exception control
Very reliable with a low pressure drop
Stejasa Butterfly Dampers are used to control and/or isolate gas flow. The design of a butterfly damper is very simple and is a cost-effective solution. Butterfly dampers have a very flexible design, and with a wide range of sizes available, this particular damper has been used throughout an extensive range of industries.
Butterfly dampers can be circular, square or rectangular and are available in carbon steel, alloy steel or stainless steel. External or internal insulation can also be added to suit the individual application. Speak to AAF to find out more.
- Wide range of sizes
- Flexible single blade design
- Robust design suitable for all applications
- High temperature resistance
- Optimized pressure drop
AAF’s Stejasa Multilouver Dampers are very similar in principle to a butterfly damper but they offer the customer higher levels of control by having more than one blade. In applications where controlling the flow of gas needs to be very carefully managed a multilouver design is the perfect option.
Multilouver dampers can be fitted with between 2-5 blades depending on the design requirements. They can be circular, square, or rectangular and are available in carbon steel, alloy steel or stainless steel. External or internal insulation can also be added to suit the individual application.
- Parallel or opposite blades operation
- Flexible multi blade design
- Robust design, suitable for all applications
- High temperature tolerance
- Optimized pressure drop
A Stejasa Tandem Damper is used when 100% sealing efficiency is required. These state-of-the-art dampers have an integrated seal air system to ensure a leak-free seal. This type of damper can be based on either a butterfly or a multilouver damper and offers the same levels of flexibility in the design process.
A Stejasa Tandem Multilouver Damper is recommended where 100% sealing is required and more than a single sealing blade is required to have greater control of the flow of gas. Speak to AAF to find out more.
- 100% sealing efficiency
- Wide range of sizes
- Flexible single or multi blade design
- Suitable for all industrial applications
- Optimized pressure drop
A Stejasa Guillotine Damper is used in applications that require an on-off gas flow. They can be designed with or without a seal air system according to the design requirements. This type of Guillotine Damper can be automatically actuated from the plant’s Distributed Control System (DCS).
AAF can supply PLC and local controls to engage with the general control of the plant. The materials and actuator arrangements are customised according to the process parameters (dust content, operation time, temperature, etc). Speak to AAF to find out more.
- High tightness ratio
- Pneumatic or electric actuator
- Rack and pinion design also available
- Wide range of sizes, for all applications
- Low pressure drop
