HVAC duct damper Heatpex ADP 160 (model ADUROADURO) by Heatpex

Heatpex ADP 160 (model ADUROADURO) is a duct damper designed for HVAC air distribution systems. Intended for 160 mm duct connections, this component provides manual regulation of airflow to balance ventilation circuits and reduce unwanted drafts. The damper is suitable for installation in both residential and commercial ventilation networks where reliable airflow adjustment and simple integration with round ducts are required.

Advantages

The damper offers straightforward mechanical operation with a compact design that fits standard 160 mm round ducts. Its construction enables stable position holding for consistent airflow settings and contributes to more even air distribution across branches of the ventilation system. The product is compatible with common duct materials and mounting methods, allowing quick installation and commissioning without complex adapters.

Suitable for

• Balancing airflow in residential ventilation systems
• Airflow regulation in small commercial HVAC branches
• Retrofit projects where 160 mm round ducts are used
• Zones requiring manual adjustment of supply or exhaust airflow

Key specifications

• Designed for 160 mm round duct connections
• Manual damper operation for adjustable airflow control
• Compact body suitable for limited space installations
• Compatible with standard ventilation duct materials

How to use

Insert the damper into a 160 mm round duct section and secure it according to the ductwork fastening method in use (clamps, screws, or pop rivets as appropriate). Adjust the damper blade to the required position to achieve the desired airflow balance. Verify airflow after adjustment and readjust if necessary to ensure consistent ventilation performance across connected rooms or zones. Perform periodic visual checks and move the control element to prevent sticking from dust accumulation.

Usage recommendations

For reliable operation, install the damper in an accessible location to allow routine inspection and adjustment. During installation, ensure airtight sealing around the connection to avoid leaks that would affect airflow measurement. If the ventilation system requires automatic control, consider pairing this manual damper with actuated dampers or control devices in other sections of the network.
