ALNOR BEND WITH GASKETS BPL-90-200 – ventilation duct elbow 90° ø200 mm

ALNOR BEND WITH GASKETS BPL-90-200 – ventilation duct elbow 90° ø200 mm is a 90-degree circular duct fitting engineered for air distribution systems with a nominal diameter of 200 mm. The elbow integrates soft gaskets at the joint interfaces to provide airtight connections between circular ducts and to facilitate reliable directional changes in HVAC ductwork. The product is intended for installation in commercial and residential ventilation systems where robust sealing and standard-sized duct transitions are required.

Advantages

The integrated gaskets reduce air leakage at joints and simplify assembly by eliminating the need for separate sealing materials. The 90° angle ensures predictable airflow direction change while maintaining a compact footprint suitable for tight installation spaces. Constructed to match standard circular duct dimensions, the fitting supports consistent system performance and easier integration with other ALNOR duct components.

Suitable for

• Changing airflow direction in HVAC duct runs in commercial buildings
• Residential ventilation systems with 200 mm nominal diameter ducts
• Retrofit and new-build installations where airtight duct connections are required
• Applications requiring compact 90° turns in supply or exhaust lines

Key specifications

• Nominal diameter: 200 mm
• Angle: 90° elbow
• Connection type: circular duct connection with integrated sealing gaskets
• Application: air distribution for ventilation and HVAC systems
• Material: compatible with standard sheet metal ductwork (matching circular duct profiles)

How to use

Fit the elbow between two sections of circular duct with the gasketed ends aligned to mating duct profiles. Ensure duct ends are clean and free of debris before insertion. Push the duct sections fully into the gasketed sockets until a secure seat is achieved; verify that gaskets are compressed evenly around the circumference to form an airtight seal. Fasten the connection according to local regulations and project requirements, using clamps or screws where appropriate to provide mechanical retention if required by the installation standard.

Usage recommendations

For optimal airtightness and long-term performance, inspect gaskets before installation and replace any damaged seals. Align ducts carefully to avoid twisting or pinching the gasket. Where required by local codes, provide additional mechanical fastening at the joint and avoid excessive bending on adjacent duct sections to reduce stress on the gasketed connection.
