## Long description

ALNOR DASL-200 is a closing damper with an integrated gasket designed for air handling and ventilation systems. The damper provides reliable shut-off and improved airtightness to reduce leakage in ductwork. It is intended for installation where controlled closing and sealing are required, enabling flow isolation, access for maintenance, and system balancing within HVAC networks.
Advantages
The DASL-200 combines a robust closing mechanism with a continuous gasket to enhance sealing performance and minimize air leakage. Its design allows straightforward integration into duct systems with secure attachment and consistent operation. Constructed for typical HVAC environments, the unit supports stable shut-off under normal system pressures and reduces the need for additional sealing materials.
Suitable for
Isolation of duct sections for maintenance or repair
Shut-off of airflow in ventilation and air handling systems
System balancing and control in commercial or residential HVAC installations
Applications requiring improved airtightness and reduced leakage
Key specifications
Function: closing damper with integrated gasket for improved sealing
Application: ventilation and air handling systems
Operation: manual or actuator-compatible closing mechanism
Sealing: continuous gasket to reduce leakage at closed position
Installation: duct-mounted design for inline shut-off and access isolation
How to use
Install the DASL-200 into the duct section according to duct dimensions and airflow direction, ensuring the gasket faces the mating flange surface for optimal sealing. Secure the damper with appropriate fasteners and, if required, connect an actuator or manual handle following manufacturer mounting points. Verify free movement of the closing element and check for proper compression of the gasket when the damper is in the closed position. After installation, perform a leakage check and adjust fastenings as needed to ensure consistent sealing performance.
Usage recommendations
Use the damper within the operating pressure and temperature ranges typical for ventilation systems; avoid exposure to corrosive agents or conditions outside standard HVAC environments. For best sealing results, inspect the gasket periodically for wear, replace if damaged, and ensure flange faces are clean and flat before installation. When connecting an actuator, follow torque and mounting instructions to prevent distortion of the closing element.
