## Long description

ALNOR DASL-160 is a closing damper with gasket designed for circular air ducts with nominal diameter 160 mm. The damper provides reliable shut-off of airflow and improved sealing where duct sections must be isolated for maintenance, balancing or system control. Built for ventilation and air-conditioning installations, the unit combines a compact circular design with an integrated gasket to reduce leakage and ensure a tighter fit in duct connections.
Advantages
The damper includes a compressive gasket that enhances airtightness compared with plain metal dampers, reducing leakage at the closed position. Its circular form factor suits standard round ducts and simplifies installation in branch lines or straight runs. The construction is intended to offer stable closure, low maintenance and compatibility with common actuator or manual control options used in HVAC systems.
Suitable for
Isolating sections of ventilation ducts for maintenance or repairs
Shutting off air supply to specific rooms or zones
Use in air-conditioning systems to control airflow balance
Integration in duct runs where improved sealing is required
Key specifications
Shape: circular for nominal diameter 160 mm
Function: closing (shut-off) damper
Sealing: integrated gasket for reduced leakage
Application: ventilation and air-conditioning ducts
Mounting: in-line installation for round ductwork
How to use
Install the damper directly into the circular duct section of matching nominal diameter using appropriate duct connectors or clamps to ensure mechanical stability. Confirm the gasket is undamaged and seated correctly before final tightening. Operate the damper manually or via compatible actuator to achieve full shut-off; verify closure and sealing by checking for airflow or using smoke/pressure test methods. Periodically inspect the gasket and moving parts and clean or replace components as needed to maintain performance.
Usage recommendations
Before installation, verify duct diameter compatibility and inspect the gasket for integrity. For optimal sealing, ensure mating duct ends are clean and properly aligned. When integrating an actuator, select a model suitable for circular dampers of this size and follow actuator manufacturer mounting instructions. Schedule routine inspections to detect wear on the gasket and ensure reliable shut-off over time.
