220x90 Low Profile Duct

220×90 Low Profile Duct | Pro-Air Supplies

The 220×90 mm low profile duct is a compact rectangular duct designed for tight ceiling cavities and restricted installation spaces commonly found in apartments, townhouses and light commercial projects. 

Its slim profile allows contractors to route ventilation systems through bulkheads and wall cavities where traditional round ductwork may not fit.

The 220×90 flat channel duct can typically handle airflow up to approximately 70–85 L/s (250–300 m³/h) when correctly installed, maintaining efficient air movement while keeping air velocity and noise levels within acceptable limits. The smooth internal surface helps minimise pressure loss and improve overall system efficiency.

At Pro-Air Supplies, the 220×90 low profile duct is commonly used for bathroom exhaust, laundry ventilation and smaller HVAC exhaust systems, offering a reliable and easy-to-install solution for modern ventilation projects where space is limited.
