Product information

Description

ALNOR DAOS-125 is a compact air return damper designed for ventilation and HVAC systems with a 125 mm duct connection. The DAOS-125 controls and regulates airflow in return ducts, allowing adjustable air passage to balance ventilation circuits and prevent backflow. Its compact circular design makes it suitable for installations where space is limited and a reliable return air control element is required.

Advantages

The ALNOR DAOS-125 provides stable airflow regulation with an adjustable blade mechanism that enables fine tuning of return air volume. The device helps prevent unwanted backflow, contributing to improved system stability and energy efficiency. Its round profile and standard connection size simplify integration into existing ductwork, and the construction is intended for durable operation in commercial and residential ventilation applications.

Suitable for

  • Balancing return airflow in small to medium ventilation circuits
  • Preventing backflow in residential HVAC systems
  • Use in compact commercial ventilation installations
  • Integration into circular ducts with a 125 mm diameter connection

Key specifications

  • Connection diameter: 125 mm
  • Type: return (backdraft) damper with adjustable blade
  • Application: ventilation and HVAC return ducts
  • Shape: circular
  • Installation: inline duct mounting for return air circuits

How to use

Install the DAOS-125 directly into the return duct with matching 125 mm connections, ensuring secure sealing at the joints to avoid leakage. Adjust the blade position to set the desired return airflow; fine tuning can be performed while the system is running to achieve balanced air distribution. Periodically inspect the damper for free blade movement and clean any accumulated dust to maintain performance.

Usage recommendations

Use the damper in conjunction with other airflow control and measurement devices for accurate balancing. Avoid exposure to corrosive atmospheres or temperatures beyond the ventilation system design limits. Schedule routine inspections and cleaning to ensure consistent operation and to prevent obstruction of the blade mechanism.
