The 220×90 to 300×60 Reducer is a purpose-built flat channel duct fitting that provides a smooth transition between 220×90mm and 300×60mm rectangular ducting systems. This transition piece bridges two of the most popular flat channel duct sizes used in Australian residential and commercial ventilation installations.
Manufactured from high-quality materials, this reducer features a gradual profile change that maintains efficient airflow while minimising turbulence and static pressure loss at the transition point. The smooth internal surfaces prevent noise generation and ensure quiet, effective ventilation performance.
This fitting is commonly used when connecting 220×90mm branch runs to 300×60mm main duct trunks, or when transitioning between different flat channel sizes within kitchen rangehood ducting, bathroom exhaust, and whole-home ventilation systems. It connects seamlessly with both 220×90mm and 300×60mm flat channel components.
The low-profile flat channel design enables installation within standard wall cavities, floor spaces, and above suspended ceilings where space is limited. Easy to install using standard duct connectors and sealant tape for secure, airtight connections throughout your ventilation system.
