SPI

The SPI are circular iris dampers designed for control and measurement of the air flow volume. The iris dampers are made of galvanized sheet steel and are equipped with a rubber seal in the place of connection with a circular duct. The SPI iris dampers have a low noise level, so there is no need for a silencer behind the controller. The iris dampers can be used to control the air flow volume even when exhausted via diffusers. The maximum ambient temperature is 70 °C.
