## Summary description

Flat duct connector AWENTA KP55-21 is designed for joining rectangular ventilation ducts with internal dimensions 55×110 mm. The connector ensures a straight, secure connection between flat duct sections in ventilation and air extraction systems. Suitable for domestic and light commercial installations where compact rectangular duct routing is required.

## Long description

Flat duct connector AWENTA KP55-21 for 55×110 mm rectangular ducts is a metal coupling element designed to join two flat ventilation duct sections with internal dimensions of 55×110 mm. It provides a straight, stable link between sections in ventilation and extraction systems often used in domestic and light commercial installations where compact rectangular routing is required. The connector fits the specified flat duct profile and maintains airflow continuity with a minimal profile.
Advantages
The connector offers a precise fit for 55×110 mm rectangular ducts, ensuring a secure mechanical joint without altering the duct profile. Its compact design reduces space requirements in tight installation areas and allows quick alignment of duct sections. Constructed from durable sheet metal, the connector resists deformation under normal operating conditions and supports straightforward sealing with common duct sealants or tapes to limit air leakage.
Suitable for
 Joining flat ventilation ducts with internal dimensions 55×110 mm
 Domestic ventilation and kitchen extraction systems
 Light commercial HVAC runs in tight or concealed spaces
 Retrofit or repair of existing rectangular ductwork
Key specifications
 Compatible internal duct dimensions: 55×110 mm
 Design: straight flat duct connector for rectangular sections
 Material: corrosion-resistant sheet metal suitable for ventilation use
 Application: indoor ventilation and extraction systems
 Installation type: mechanical coupling for continuous airflow
How to use
Measure and prepare the ends of the two flat duct sections to ensure they are clean and properly aligned. Slide the AWENTA KP55-21 connector over the mating ends so that the duct profiles engage evenly along the length of the coupling. Secure the joint using appropriate fasteners or clamps where required, and apply duct sealant or aluminium foil tape along the seams to reduce air leakage. Verify alignment and airflow after installation and make any minor adjustments to ensure a straight duct run.
Usage recommendations
For best performance, use the connector with flat ducts that match the 55×110 mm internal dimensions closely, and seal joints with compatible HVAC tape or sealant. In installations where condensation or high humidity may occur, verify material suitability and consider additional corrosion protection or insulation as required by the system design.
