The 220×90 90 Degree Vertical Bend is a flat channel duct fitting that enables a 90-degree direction change in the vertical plane within 220×90mm rectangular ducting systems. This fitting allows ductwork to transition between horizontal and vertical runs through floors and ceiling penetrations.
While 90-degree bends create more airflow resistance than 45-degree alternatives, they are essential when space constraints demand a sharp vertical direction change. The compact 220×90mm profile fits within standard wall cavities and ceiling spaces.
Commonly used in residential kitchen rangehood ducting, bathroom exhaust systems, and multi-level ventilation installations where ducts need to transition between floors or from horizontal ceiling runs to vertical wall runs.
Manufactured with smooth internal surfaces to maintain airflow. Compatible with all 220×90mm flat channel components. Install with duct connectors and seal joints with duct tape for airtight performance.
