Description: This regulator is designed to retain constant airflow within ventilation systems. The device operates without a power supply and can be used for intake and exhaust installations in comfort and industrial ventilation. The regulator casing and most of its regulating mechanism is made of a galvanized sheet while the adjusting damper is made of an aluminum sheet. The system operates by balancing the moment the damper closes, which is triggered by airflow the moment the damper opens. When the pressure differential in the regulator grows (e.g. closing of the damper in the installation, increase of airflow in the air-handling unit), the damper will close by itself to maintain the set airflow.
