300×60 Low Profile Duct | Pro-Air Supplies

The 300×60 mm low profile duct is a space-saving ventilation solution designed for commercial HVAC installations where ceiling cavity space is limited. Commonly used in apartments, offices, hotels and multi-residential projects, this slim rectangular duct allows efficient airflow while fitting easily within tight bulkheads and ceiling spaces.

Despite its compact profile, the 300×60 flat channel duct can handle airflow up to approximately 90–110 L/s (320–400 m³/h) when installed correctly, maintaining good air velocity and minimal pressure loss. The smooth internal surface improves airflow efficiency and reduces noise within the system.

At Pro-Air Supplies, our 300×60 low profile duct is ideal for bathroom exhaust, laundry ventilation and light commercial HVAC systems, offering contractors a reliable, easy-to-install solution for modern ventilation projects.

Pro-Air Supplies stocks 300×60 low profile duct systems for HVAC contractors across Melbourne and Victoria. Available for pickup from our Pakenham warehouse or delivery across Australia.
