Product information

Description

The ALNOR DASL-100 closing damper with gasket is a ventilation damper designed to regulate and isolate airflow in HVAC duct systems. Built for applications that require controlled shut-off and reduced leakage, this damper incorporates a gasketed edge to improve sealing performance when closed. The unit is suitable for integration into round or rectangular ducts depending on installation requirements and can be used for balancing air distribution or providing isolation during maintenance.

Advantages

The gasketed sealing edge reduces air leakage and improves shut-off effectiveness compared with non-gasketed dampers. The design allows straightforward integration into existing ductwork and supports reliable operation for airflow regulation. Its construction is intended to withstand the typical conditions of mechanical ventilation systems and to provide consistent performance for balancing and isolation tasks.

Suitable for

  • Regulating airflow in ventilation and HVAC systems
  • Isolating duct sections for maintenance or repairs
  • Balancing air distribution between zones
  • Installation in round or rectangular duct configurations

Key specifications

  • Function: closing damper with sealing gasket for shut-off and regulation
  • Compatibility: designed for duct integration in ventilation systems (round or rectangular layouts)
  • Sealing: gasketed edge to reduce leakage when closed
  • Application area: HVAC ventilation ducts for commercial or residential systems

How to use

Install the damper into the duct run according to the duct shape and system layout, ensuring the gasketed edge aligns with the mating surface to achieve a proper seal. Connect any actuator or manual control mechanism as required by the installation, then verify operation by cycling the damper and checking for smooth movement and effective closure. Use airflow measurement or balancing procedures after installation to set the damper position for the required airflow rates.

Usage recommendations

For optimal sealing, ensure mating duct surfaces are clean and free from damage before fitting the damper. Periodically inspect the gasket for wear and replace if compression or deterioration reduces sealing performance. If the damper is fitted with an actuator, follow the actuator manufacturer's mounting and commissioning instructions to avoid misalignment or over-torque that could impair operation.
