How to Choose the Right Dampers and Actuators?

To ensure a ventilation system operates optimally, it is often not enough to simply turn on the heat recovery unit. Dampers and actuators allow you to "fine-tune" the system – directing airflows, balancing them between different rooms, or even completely shutting off certain branches. The correct selection and use of these components are key to an efficient and customized ventilation system.

Main Purposes of Dampers

In our assortment, you will find various types of dampers that perform different functions:

• Control Dampers: This is one of the main tools for balancing a ventilation system. They allow you to precisely set how much air travels through a specific duct branch. Some models (e.g., IRIS) have special measuring points for accurate airflow adjustment.
• Shut-off Dampers: Designed to completely stop the movement of air in a duct. They can be controlled manually or automatically using actuators.
• Back Draught Dampers (Non-return Dampers): These dampers operate automatically and prevent air from moving in the reverse direction. They are particularly important for preventing cold outdoor air from entering the system when it is turned off or to protect against the spread of odors between rooms.

Actuators – Automated Control

Actuators are electromechanical devices mounted on damper spindles that allow them to be controlled remotely or automatically. For example, a spring-return actuator can automatically close a damper in the event of a power failure, thus protecting the system.

What to Consider When Choosing?

• • Purpose: Clearly determine what function the component needs to perform – regulate, shut off, or prevent back draught.
  • Duct Diameter: Choose a damper that matches the diameter of your ductwork.

- Control Method: Decide whether you will control the damper manually or if you require automated control with an actuator.

- Airtightness: Pay attention to the damper's airtightness class. A higher class means lower air leakage and a more efficient system operation.

Properly selected dampers and actuators are an unseen but vital part of an effective ventilation system. Browse our assortment and find the solutions you need for balancing and controlling your system. If you have any questions, our specialists are always ready to help.
