## Long description

MAGNAPLAST Trójnik dBA 110/75/67 SKOLAN-dB is a low-noise duct branch (reducing tee) designed for ventilation systems. It provides a compact junction that joins ducts with nominal diameters of 110 mm, 75 mm and 67 mm, combining airflow distribution with acoustic attenuation. The component is intended for installations where reduced transmission of fan and airflow noise is required while maintaining efficient air passage in residential and commercial HVAC systems.
Advantages
The MAGNAPLAST reducing tee integrates sound-damping features to decrease noise propagation through branch connections. Its stepped diameters enable straightforward adaptation between different duct sizes without additional adapters, supporting compact and space-efficient layouts. Constructed from materials suitable for ventilation use, the component facilitates reliable air distribution and contributes to a quieter indoor environment when installed as part of a ventilation network.
Suitable for
 Residential ventilation and apartment exhaust systems
 Small commercial HVAC installations and office ventilation
 Bathrooms, kitchens and utility rooms requiring quieter exhaust
 Retrofit projects where downsizing duct runs is necessary
Key specifications
 Connection diameters: 110 mm, 75 mm and 67 mm
 Type: reducing tee (duct branch)
 Function: noise-reducing junction for air distribution
 Application: ventilation and exhaust air systems
 Design: compact footprint for constrained routing
How to use
Install the MAGNAPLAST Trójnik dBA in-line with ductwork so that airflow direction and branch orientation match the installation design. Fit the corresponding duct sections onto the 110 mm, 75 mm and 67 mm spigots and secure according to standard ventilation installation practice (seal joints with suitable tape or sealant and use clamps or screws where applicable). Ensure the tee is supported to avoid strain on connected ducts and that access for maintenance is retained. The sound-reducing properties work passively once the tee is integrated into the operating ventilation system.
Usage recommendations
For optimal acoustic performance, pair the reducing tee with compatible ducting materials and avoid sharp bends or abrupt transitions near the junction; maintain proper airflow rates as specified for the system and follow local ventilation codes for installation and sealing.
