## Summary description

AWENTA vertical flat branch KP55-26/100 is a ventilation duct fitting with outlet sizes 55x110 mm and 100 mm, supplied as a single piece. Designed to connect rectangular and round ducts in vertical installations, it provides airflow distribution in ventilation systems for residential or commercial buildings. Suitable for use in exhaust, supply and transfer ductwork where space-saving flat connections are required.

## Long description

AWENTA vertical flat branch KP55-26/100 is a ventilation duct fitting designed to connect a rectangular duct profile measuring 55 x 110 mm to a circular duct with a 100 mm diameter in vertical installations. Supplied as a single piece, this component enables transition between flat and round ductwork while preserving airflow direction and minimizing pressure losses. It is intended for use in residential and commercial ventilation systems where a compact vertical connection is needed for exhaust, supply or transfer air paths.
Advantages
The flat branch provides a stable, low-profile transition between rectangular and round ducts, reducing the need for on-site fabrication. Constructed to match common duct dimensions, it simplifies installation and alignment in tight vertical shafts. Its shape helps maintain airflow efficiency and reduces turbulence at the junction, supporting consistent ventilation performance. Being a single-piece fitting, it reduces potential leak points compared with multi-part adapters.
Suitable for
 Connecting 55 x 110 mm rectangular ducts to Ø100 mm round ducts in vertical runs
 Exhaust air ductwork in bathrooms, kitchens or utility rooms
 Supply and transfer duct connections in residential and light commercial systems
 Space-constrained installations where a flat-to-round transition is required
Key specifications
 Rectangular outlet dimensions: 55 x 110 mm
 Circular outlet diameter: 100 mm
 Orientation: vertical flat-to-round transition
 Supply: single-piece fitting for duct transitions
How to use
Install the flat branch in the vertical section of the duct run, aligning the rectangular outlet with the flat duct and the circular outlet with the round duct. Secure both connections according to the ventilation system practice — typically with clamps, sheet-metal screws or approved duct tape and sealing compound where required to maintain airtightness. Ensure the fitting is oriented so airflow follows the designed direction and that the surrounding structure supports the weight and alignment of connected ducting. Check for proper clearance and access for inspection after installation.
Usage recommendations
Before installation, verify compatibility with the existing duct profiles and confirm that the 55 x 110 mm flat section and Ø100 mm circular section match the system. Use appropriate sealing and fastening methods to prevent leaks and reduce noise. For best results in ventilation performance, avoid sharp bends immediately adjacent to the fitting and allow a short straight section of duct where possible.
