The 500×75 to 350×75 Reducer is a precision-engineered flat channel duct fitting designed to provide a smooth transition between 500×75mm and 350×75mm rectangular ducting systems. This reducer is essential when your ventilation layout requires a change in duct size, allowing you to connect larger capacity duct runs to smaller sections without compromising airflow efficiency.

Manufactured from high-quality materials, this reducer ensures a gradual taper that minimises turbulence and static pressure loss at the transition point. The smooth internal profile maintains efficient airflow, preventing noise and vibration that can occur with abrupt size changes in ducting systems.

This fitting is commonly used in kitchen rangehood ducting installations, whole-home ventilation systems, and commercial HVAC setups where different sections of the duct run require different duct sizes. It connects seamlessly with both 500×75mm and 350×75mm flat channel components including channel ducts, duct connectors, bends, and T-pieces.

The low-profile flat channel design allows installation within standard wall cavities, floor spaces, and above suspended ceilings where traditional round ducting would not fit. Easy to install with standard flat channel duct connectors and sealant tape for airtight joints.
