Single leaf air volume control damper for installation in round ducts. Consists by a cylindrical body with a round blade inside which rotates from 0ο (closed) up to 90ο (open). The cylindrical body and the blade are made by galvanized sheet steel. The blade angle is manually regulated with plastic damper controller.
Also is available in the following executions:
- DAF-M: With metal damper controller.
- DAF-ON/OFF 220V: Regulation with electric actuator on/off 220V.
- DAF-ANALOGUE 24V: Regulation with electric actuator analogue 24V.
- DAF-M-S: With metal damper controller and double blade with rubber seal for better air tightness.
- DAF-S-ON/OFF 220V: Regulation with electric actuator on/off 220V and double blade with rubber seal for better air tightness.
- DAF-S-ANALOGUE 24V: Regulation with electric actuator analogue 24V and double blade with rubber seal for better air tightness.
In DAF with the electric actuator, if we have big air temperature in the air duct, we can install the electric actuator in distance 3cm from the cylindrical body (-Α) for protection.
