Round duct tee AWENTA KO100-26 — 100 mm circular ventilation duct fitting

AWENTA KO100-26 is a 100 mm round duct tee for circular ventilation systems. This metal fitting allows connection of three 100 mm ducts to create a branch or redistribute airflow in compact HVAC layouts. Designed for residential and light-commercial installations, the AWENTA round duct tee supports both supply and exhaust lines and helps simplify duct routing where space is limited.

Advantages

The fitting is made of metal for dimensional stability and reliable airflow transfer. Its consistent 100 mm diameter on all three outlets ensures airtight connections with standard circular ducts and accessories. The compact tee shape reduces the need for additional fittings, which can simplify installation and save space. The product is compatible with common ventilation systems used in homes and small commercial buildings.

Suitable for

• Branching supply air in residential ventilation systems
• Creating exhaust branches for kitchens, bathrooms or utility rooms
• Compact duct routing in apartments, small offices and retail premises
• Retrofit projects where a simple three-way junction is required

Key specifications

• Nominal diameter: 100 mm
• Shape: round tee with three equal outlets
• Material: metal (stamped/formed sheet metal)
• Application: ventilation duct branching for supply and exhaust
• Compatible with standard 100 mm circular ducts and clamps

How to use

Position the tee at the planned junction point and ensure the surrounding ductwork is accessible. Insert 100 mm ducts into each outlet, aligning seams and edges for a flush fit. Secure connections with appropriate clamps, metal tape or sealant to maintain airtightness. Support the assembly with hangers or brackets if required to prevent stress on joined ducts. Verify airflow direction and balance the system after installation.

Usage recommendations

When installing the AWENTA 100 mm round duct tee, check for proper sealing at joint interfaces and avoid sharp bends immediately adjacent to the tee to reduce pressure losses. For systems requiring high airtightness, use sealing tape or silicone sealant at each connection and use mechanical clamps. Consider adding vibration isolators or flexible connectors where the duct meets fans or noisy equipment to reduce transmitted noise.
