## Long description

The AWENTA Flat duct reducer KP75-29 connects rectangular ventilation ducts from 75×150 mm to 55×110 mm, providing a controlled transition between different flat duct sizes. Made for ventilation and air-conditioning systems, this reducer maintains airflow continuity and helps integrate ducts of varying cross-sections in retrofit projects or new installations where space or layout constraints require resizing.
Advantages
This flat duct reducer offers a precise dimensional match for common rectangular duct sizes, ensuring secure mechanical connection and reduced leakage at the joint. Its rigid rectangular profile maintains airway geometry to minimise turbulence and pressure loss. The component’s compact tapered design facilitates installation in confined spaces and allows straightforward integration with standard flat duct fittings.
Suitable for
Residential and commercial ventilation systems requiring size transition
Air-conditioning ductwork adjustments during renovations
Installations with limited space where rectangular-to-rectangular resizing is needed
HVAC assemblies that require reliable airflow continuity between different duct sections
Key specifications
Input dimension: rectangular 75 × 150 mm
Output dimension: rectangular 55 × 110 mm
Shape: tapered rectangular reducer for flat ducts
Intended application: ventilation and air-conditioning systems
Installation orientation: compatible with horizontal or vertical flat duct runs
How to use
Position the reducer between the two matching flat duct sections so that the larger end faces the 75×150 mm duct and the smaller end aligns with the 55×110 mm duct. Ensure both duct ends are clean and square for a tight fit. Fasten the joints using appropriate sheet-metal screws, rivets, or clamps and apply sealant or tape rated for HVAC use to minimise air leakage. Support the assembly as required to prevent strain on adjacent ductwork.
Usage recommendations
Verify that the reducer dimensions match existing duct sizes before installation. Use compatible sealing materials and secure fixings to maintain system efficiency and reduce noise. For best results, integrate the reducer within a properly sized duct run and check airflow and static pressure after installation.
