Õhuklapp

õhuklapp is an Estonian term that translates to "air damper" or "air valve" in English. It refers to a device used to control the flow of air in a ventilation system, ductwork, or chimney. õhuklapp can be found in various applications, from residential heating and cooling systems to industrial exhaust systems.

The primary function of an õhuklapp is to regulate the volume of air passing through a specific point. This can be achieved manually by adjusting a lever or wheel, or automatically using actuators that respond to temperature, pressure, or a programmed schedule. Automatic õhuklapp mechanisms are crucial for maintaining consistent airflow and optimizing energy efficiency in buildings.

There are several types of õhuklapp, including butterfly dampers, louvre dampers, and opposed blade dampers. Butterfly dampers consist of a single plate that rotates on a central spindle, while louvre dampers utilize multiple parallel blades that pivot simultaneously. Opposed blade dampers have blades that move in opposite directions, offering finer control.

In chimneys, an õhuklapp, often referred to as a flue damper, can be used to reduce heat loss when the fireplace or stove is not in use. It seals the flue and prevents warm air from escaping the house. Similarly, in ventilation systems, õhuklapp can be used to balance airflow between different zones, isolate sections for maintenance, or shut off airflow completely. The precise design and application of an õhuklapp depend on the specific requirements of the system it serves.
