## Long description

The DARCO PJS Choke with Knob for Hot Air Distribution Ø125 mm is a precision-engineered component designed to manage airflow within heating and ventilation systems. This manual damper allows users to effectively regulate the volume of hot air passing through ductwork, facilitating balanced temperature distribution throughout a building. Built for durability, the unit ensures consistent performance in demanding environments, making it an essential element for maintaining thermal comfort and system efficiency.
Advantages
The primary benefit of this choke is its intuitive manual control mechanism, which allows for quick and accurate adjustments to airflow without the need for complex tools. Its robust construction ensures long-term reliability even when exposed to the elevated temperatures typical of hot air distribution systems. By enabling precise regulation, it helps optimize the energy efficiency of heating setups, preventing overheating in some areas while ensuring sufficient warmth in others.
Suitable for
Residential heating and ventilation systems
Hot air distribution networks from fireplaces or furnaces
Balancing airflow between multiple rooms
HVAC ducting installations requiring manual flow regulation
When it may not be suitable
This product is not designed for use in systems requiring automated or remote-controlled airflow adjustments, as it relies entirely on manual operation via the integrated knob. It is also not intended for industrial environments involving corrosive gases or extreme pressure levels that exceed standard residential or light commercial ventilation specifications.
Key specifications
Diameter: 125 mm
Control type: Manual knob
Application: Hot air distribution
Material: Durable metal construction
How to use
To install the choke, insert it into the 125 mm diameter air duct at the desired location, ensuring a secure and airtight fit. Once installed, the airflow can be adjusted by turning the external knob. Rotating the knob changes the position of the internal damper blade, thereby increasing or decreasing the air volume passing through the duct. It is recommended to perform adjustments gradually to achieve the desired temperature balance in the connected rooms.
What to consider before purchase
Verify that your existing ductwork has a 125 mm diameter
Ensure there is sufficient physical access to the knob for manual adjustment
Confirm the temperature resistance of the duct system matches the intended use
Usage recommendations
Regularly inspect the damper mechanism to ensure it remains free of dust and debris, which can accumulate over time and affect the precision of the airflow regulation. Periodically check the connection points to ensure the unit remains firmly seated within the ductwork.
