## Summary description

Flat channel connector with integrated backdraft (non-return) damper by AWENTA, model KP204-22, sized 60×204 mm. Designed for connecting rectangular ventilation ducts while preventing reverse airflow, it suits HVAC and residential ventilation installations. Durable construction enables use in supply or exhaust systems where one-way air flow control is required.

## Long description

Flat channel connector with integrated backdraft damper AWENTA KP204-22 60×204 mm is a rectangular ventilation accessory designed to join flat ducts while preventing reverse airflow. Manufactured for HVAC and residential ventilation systems, this connector combines a compact profile with a built-in non-return damper that allows air to flow in one direction and closes to block backflow when the system is idle. The component is intended for inline installation where space is limited and one-way airflow control is required.
Advantages
The flat channel connector features an integrated backdraft damper that eliminates the need for a separate non-return valve, reducing installation time and potential leakage points. Its rectangular 60×204 mm profile provides a low-profile connection suitable for concealed or shallow installations. The construction materials and damper mechanism are designed for reliable operation in supply or exhaust lines, ensuring consistent one-way airflow control and improving overall ventilation performance.
Suitable for
 Connecting rectangular/flat ventilation ducts in residential and commercial HVAC systems
 Supply air or exhaust lines where prevention of reverse airflow is required
 Installations with limited depth or where a low-profile connector is needed
 Retrofits and repairs where an integrated damper simplifies the replacement process
Key specifications
 Connector shape: rectangular / flat channel
 Nominal cross-section: 60 × 204 mm
 Integrated function: backdraft (non-return) damper
 Application: supply or exhaust ventilation ducts
 Mounting: inline connection between flat ducts
How to use
Install the flat channel connector inline between two matching rectangular duct sections, ensuring the damper flap is oriented to allow airflow in the intended direction. Secure the connection with appropriate fasteners or sealing tape compatible with the duct material to maintain airtight joints. Check that the damper operates freely and closes fully when airflow stops. If required, acoustical or thermal insulation can be applied externally without obstructing the damper movement.
Usage recommendations
Verify duct dimensions before installation to confirm a correct fit for the 60×204 mm profile. Periodically inspect the damper for dust buildup or mechanical obstruction, and clean as necessary to maintain reliable one-way operation. Use in environments within typical residential and commercial ventilation temperature and humidity ranges; avoid exposure to corrosive chemicals or extreme conditions unless additional protective measures are applied.
