Product information

Description

ALNOR DASL-125 is a closing damper with gasket designed for round air ducts with a nominal diameter of 125 mm. The unit provides airtight shut-off by means of an integrated gasket and a closing mechanism, allowing reliable isolation of duct sections and prevention of unwanted airflow and leakage in ventilation and HVAC systems.

Advantages

The damper offers tight sealing thanks to the integrated gasket, reducing air leakage when closed. Its round design matches standard Ø125 mm ducts for straightforward installation. Construction and materials are selected for typical ventilation use, providing consistent performance for controlling airflow and isolating duct segments in residential and commercial systems.

Suitable for

Sealing and isolating sections of round ventilation ducts with 125 mm diameter
Controlling airflow in HVAC and ventilation systems
Preventing backflow and leakage in ductwork
Use in residential and light-commercial ventilation installations

Key specifications

Applicable duct diameter: 125 mm nominal
Type: closing damper with integrated gasket for airtight shut-off
Shape: round
Function: manual or system-actuated closure to isolate duct sections and control airflow
Typical application: ventilation and HVAC ductwork sealing and isolation

How to use

Install the ALNOR DASL-125 in a section of round ductwork with a matching 125 mm internal diameter, ensuring the gasket faces the sealing side. Secure the damper into the duct using appropriate fasteners or clamps compatible with the duct material. Operate the closing mechanism to achieve a full seal when isolation is required; verify the gasket sits evenly around the circumference to maintain airtightness. Inspect the damper and gasket periodically and clean or replace the gasket if signs of wear or damage appear.

Usage recommendations

Verify compatibility with the duct material and nominal diameter before installation. Ensure access for inspection and maintenance and avoid exposing the damper to corrosive conditions or temperatures beyond the typical range for ventilation components. Replace a damaged gasket promptly to preserve airtight performance.
