IRIS Damper

Product Description

The IRIS Damper is a precision airflow control device designed for accurate air volume regulation and measurement in round duct systems. Unlike standard butterfly dampers, it uses an iris diaphragm mechanism with multiple interlocking blades that adjust concentrically, similar to a camera iris. This design enables smooth, continuous, and highly accurate airflow adjustment while maintaining stable flow characteristics.

Equipped with integrated pressure measuring ports (pressure taps), the IRIS damper allows technicians to measure differential pressure and calculate airflow directly, making it an ideal solution for HVAC commissioning, air balancing, and system optimization. Its high airtightness and precise repeatability make it especially suitable for projects requiring reliable airflow control and measurement.

IRIS dampers are widely used in commercial buildings, hospitals, laboratories, clean environments, and other precision ventilation systems. In many European HVAC projects, they are considered a standard air balancing component, while in Australia and the Middle East they are commonly used in higher-end engineering applications.
