Dampers serve as airflow capacity regulators in the ducts. They control the air supply to the individual users. These dampers are of the butterfly type and allow adjustment of 90° from fully open to closed position. 5 control methods are available: Mechanical, electrical, thermostat , remote control temperature Control, and R.F thermostat . The thermostatic method allows to control the dampers proportionally regarding the difference between the actual Room temperature and the desired temperature. The oval shape of the damper enables the use of very low ceiling elevations.
