Duct Reducer – 500mm – 300mm

Duct Reducer – Spiral Duct Size Transition Fitting

Smooth, Safe Transition Between Duct Sizes

The Duct Reducer is designed for use in Heat Recovery Ventilation (HRV) and Mechanical Ventilation (MVHR) systems, allowing you to connect different duct diameters while maintaining proper airflow and minimizing pressure loss.

This fitting is ideal when transitioning from one duct size to another to help maintain air velocity, reduce resistance, and ensure balanced system performance.

✅ Key Features:

• Male-to-Male Connection
  Both ends are designed to slip inside standard spiral ducting, ensuring a secure and easy fit.

• Hemmed Rim on Small End
  Provides a safe edge for installers, reducing the risk of cuts or damage during handling.

• Airflow Optimized
  Smooth internal transition helps maintain airflow efficiency and reduce turbulence.

• Versatile Use
  Suitable for ventilation, HRV/MVHR, ducted heating, and air conditioning systems.

• Multiple Sizes Available
  A wide range of reducer sizes to suit different duct configurations.
