HVAC systems are composed of a range of large and small components that all work together to make sure that air properly flows throughout your home. Dampers are a significant and essential piece of HVAC system mechanics, and help regulate the air quality and temperature of your home. dampers help to control air flow throughout your HVAC system and ensure that your HVAC system doesn’t get overloaded. Dampers are usually placed in particular areas of your home, and can’t be installed just anywhere in your HVAC system. When dampers are open, they allow air to move through them, and when closed, they redirect airflow to a different part of your home. There are many different kinds of dampers – some of which require manual adjustment and repairs, while others can be controlled with wireless technology.
Different Types of HVAC Dampers
- Butterfly Flat Dish Dampers
These dampers are made of special plates that are attached to hinges in a way that resembles butterfly wings. They are simple to install, and move air in a single direction. They are commonly found in HVAC systems that have round ducts, and are fantastic for preventing air from backdrafting.
- Blade Dampers
There are two main types of blade dampers: opposed blade dampers and parallel blade dampers. opposed blade dampers have multiple blades that automatically move, and parallel blade dampers are installed parallel from one another. opposed blade dampers are more popular, as they provide more specific control over airflow, however parallel blade dampers are those who want a consistent and constant flow of air to stay in place.
- Louver Dampers
