## Long description

Low-noise MAGNAPLAST Trójnik dBA 125/110/45 SKOLAN-dB is a ventilation duct T-piece designed for branching circular ductwork with main diameter 125 mm and branch diameter 110 mm at a 45° take-off. The fitting incorporates acoustically optimized material and geometry to reduce airborne noise transmission in HVAC systems while maintaining compact physical dimensions for installations in ceilings, walls, or service voids. It is suitable for supply and extract airflow connections where quieter operation and consistent airflow distribution are required.
Advantages
The T-piece offers reduced sound transmission through the duct network thanks to integrated low-noise construction and SKOLAN-dB acoustic lining. Its 45° branch minimizes flow resistance and turbulence compared with perpendicular branches, supporting efficient airflow and lower pressure loss. The compact design simplifies installation in confined spaces and provides stable mechanical connection points for circular ducts, ensuring reliable sealing and alignment.
Suitable for
Residential ventilation systems requiring noise control
Commercial and office HVAC installations with compact routing needs
Bathroom or kitchen extract systems where a 45° branch improves routing
Supply air distribution in apartments or light-duty commercial spaces
Key specifications
Main duct diameter: 125 mm
Branch duct diameter: 110 mm
Branch angle: 45°
Acoustic lining: SKOLAN-dB low-noise material
Material: durable ventilation-grade plastic (manufacturer standard)
Connection type: circular duct spigots for push-fit or clamp fastening
How to use
Align the T-piece with the prepared circular ducts, ensuring the 125 mm spigot matches the main run and the 110 mm spigot aligns with the branch. Push or slide the duct ends onto the spigots and secure with appropriate clamps or sealing tape to achieve an airtight joint. Observe recommended clearances for access and acoustic lining orientation during installation. After mechanical fastening, test the system for airflow balance and make adjustments to dampers or terminal devices as needed.
Usage recommendations
Install the T-piece with sufficient straight duct runs upstream and downstream to minimize flow disturbances; allow for routine inspection access and avoid compressing the acoustic lining. Use compatible clamps and elastic seals to preserve acoustic performance and airtightness.
