External Corner 90x65 for Ducting AB KLIMA (model 0906AE)

AB KLIMA External Corner 90x65 (model 0906AE) is a rectangular ducting component designed to change the direction of airflow by 90° in ventilation systems. It is intended for rectangular ducts with cross-section dimensions of 90 x 65 mm and is suitable for installation in residential and light commercial HVAC and extractor duct networks where a compact, right-angle turn is required.

Advantages

The external corner provides a compact and rigid way to redirect airflow without requiring flexible ducting or custom fabrication. Its rectangular profile preserves the duct cross-section through the bend to maintain predictable airflow characteristics. The product is manufactured for compatibility with standard rectangular ducting of the specified size, allowing straightforward connection and integration into existing runs. Its geometry helps reduce installation space compared with larger-radius bends and supports consistent air distribution when installed with proper sealing.

Подходит для

• Перенаправление воздушного потока в системах вентиляции с прямоугольными каналами 90×65 мм
• Узкие пространства и места, где требуется компактный 90° поворот воздуховода
• Вытяжные каналы кухонь, ванных комнат и бытовых зон
• Небольшие коммерческие помещения с низкопрофильными вентиляционными трассами

Key specifications

• Intended duct cross-section: 90 × 65 mm rectangular
• Design: external 90° corner for rectangular ducting
• Application: ventilation and extractor duct systems
• Installation: rigid connection to matching rectangular ducts with appropriate sealing
• Typical use environments: residential and light commercial HVAC

How to use

Measure and confirm the connected duct sections are the specified rectangular size before installation. Position the external corner so that the two mating duct ends align squarely and ensure there is sufficient clearance for the 90° turn. Join the corner to the ducts using the recommended mechanical fixings and sealant for ventilation ducts (e.g., appropriate foil tape or sealant suitable for HVAC use) to ensure airtight connections. Support the adjacent duct runs as required by local installation standards to prevent sagging or stress on the corner joint.

Usage recommendations

For best performance, avoid sharp transitions or multiple tight bends in short runs; where possible use gradual routing to reduce pressure drop. Inspect and maintain seals periodically to prevent air leakage and ensure the corner remains fixed and free of obstruction in regular ventilation maintenance cycles.
