## Summary description

Manual balancing damper SpiroFlex PJ160-OC with 160 mm nominal diameter (Ø160) for duct airflow regulation. Hand-operated occluding damper provides coarse adjustment of air volume in ventilation systems, enabling zone balancing, airflow restriction and maintenance access. Suitable for round ducts in HVAC installations where simple, reliable manual control is required.

## Long description

SpiroFlex manual balancing damper PJ160-OC with a nominal diameter of 160 mm is a hand-operated occluding damper designed for basic airflow regulation in round duct HVAC systems. It provides a simple mechanical method to restrict or allow air passage, enabling coarse balancing between ventilation zones and straightforward isolation for maintenance. The device is intended for installations where reliable manual adjustment is preferred over motorised control and when a compact, durable damper for Ø160 ducts is required.
Advantages
The SpiroFlex PJ160-OC offers a durable mechanical design and easy hand operation without the need for electrical power. Its occluding blade allows effective coarse control of air volume, while the compact cylinder form fits standard 160 mm round ducts. The unit is suitable for repetitive manual adjustments and straightforward installation into existing ductwork. Its construction minimises moving parts and simplifies maintenance in typical ventilation applications.
Suitable for
Balancing airflow between ventilation zones in residential and commercial systems
Restricting airflow to individual branches in round Ø160 ductwork
Manual isolation of duct sections for maintenance or testing
Applications where a non-powered, low-complexity damper is preferred
Key specifications
Nominal duct diameter: 160 mm
Actuation type: hand-operated (manual)
Damper type: occluding (coarse airflow control)
Intended duct shape: round
Primary function: airflow regulation and zone balancing
How to use
Install the damper into the round Ø160 duct section according to standard ductwork practice, ensuring airtight connections and correct orientation of the blade. Operate the hand control to adjust the blade position until the desired airflow restriction or balance is achieved. For coarse balancing, begin with a partially closed position and fine-tune by incremental adjustments while measuring airflow or monitoring system performance. The unit can be left at a fixed setting for long-term balancing or adjusted periodically as system requirements change.
Usage recommendations
Use basic airflow measurement tools or system indicators when setting the damper to achieve repeatable balancing results. Avoid forcing the actuator beyond its mechanical limits and schedule periodic visual inspections to confirm free blade movement and integrity of duct connections.
