Gravity Grilles
Shop gravity grilles for ducted air conditioning and gas ducted heater installations at FastFlex, Melbourne's trade HVAC wholesaler. Gravity grilles feature self-closing blades that open under positive air pressure when the system is running and fall shut by gravity when airflow stops. This makes them ideal for exhaust and supply air outlets where passive closure is required to prevent backdraught, cold draughts, or pest entry when the system is off.
This plastic gravity grille is available in a range of sizes to suit common duct outlet dimensions across residential and light commercial installations in Victoria. The lightweight plastic construction is corrosion-resistant and easy to install into wall or ceiling openings.
