The round butterfly damper is a type of valve used in ventilation systems to regulate or shut off airflow. The valve gets its name from the butterfly-shaped disc placed in the center of the ventilation duct. This disc rotates around a central axis, allowing the airflow to be partially or fully obstructed.
How does a round butterfly damper work?
A round butterfly damper operates using a disc that rotates around a central axis within the ventilation duct. When the damper is open, air flows freely through the duct. When the damper is closed, the disc blocks the airflow completely or partially, depending on how far the damper is turned. This simple yet effective operation makes the butterfly damper ideal for quickly and efficiently regulating airflows in various ventilation systems.
Where (or when) is a butterfly damper commonly used?
Butterfly dampers are commonly used in ventilation systems of commercial, industrial, or residential buildings. The butterfly dampers are ideal for applications where quick and precise airflow regulation is needed, such as in ventilation systems and air conditioning systems.
The different variants of round butterfly dampers in our range
Ventilationland offers a wide range of round butterfly dampers with sizes ranging from 80mm to 500mm. It is important that the round butterfly damper is installed in a ventilation duct of the same size. Additionally, we also offer various designs and accessories for the round butterfly damper:
- Fire Butterfly Damper Round EI60S and EI120S: these butterfly dampers provide fire protection for 60 or 120 minutes. These dampers are ideal for situations where fire safety is a high priority.
- Fire Butterfly Damper Round with Air valve EI60S and EI120S: these butterfly dampers combine the fire-resistant properties of the butterfly damper with a Air valve. This provides additional control over airflow in emergency situations.
- Fire Butterfly Damper Round End Switch Kit: the end switch signals when the damper is fully closed. This is essential for monitoring and safety.
- Fire Butterfly Damper Round Thermal Fuse 72°C Kit: this kit activates the damper at a temperature of 72°C. This provides extra protection in case of fire.
The difference between a butterfly damper and a smoke and fire-resistant butterfly damper
The standard butterfly damper is designed to regulate or shut off airflow in a ventilation system but does not provide specific protection against fire or smoke. A smoke and fire-resistant butterfly damper, on the other hand, is specially designed to close upon detection of smoke or heat, thereby preventing the spread of fire and smoke through the air ducts. The fire-resistant butterfly damper is equipped with a special seal and mechanism that ensures it effectively closes and withstands high temperatures in the event of a fire.
What are the benefits of a round butterfly damper?
A butterfly damper offers several advantages:
- Efficient airflow regulation: the rotating disc allows for quick and precise control of airflow.
- Space-saving design: the butterfly damper takes up little space in the ventilation system, making it ideal for installations with limited space.
- Versatility: the butterfly dampers are available in various sizes and designs, making them suitable for many situations.
For which ventilation ducts is the round butterfly damper suitable?
The round butterfly damper is suitable for installation in round ventilation ducts, or ventilation pipes. They fit perfectly in round pipes and ensure reliable and efficient airflow.
How to install and maintain a round butterfly damper?
The installation of the round butterfly damper is relatively straightforward. The damper must be accurately placed in a ventilation duct with the same diameter. Ensure that the damper is securely fastened and can rotate freely to regulate airflow.
The maintenance of the butterfly damper involves regularly inspecting and cleaning it to prevent dust and dirt from obstructing its operation. It is also essential to regularly test the damper's operation to ensure it functions properly.
