Backdraft Shutters

Backdraft shutters are essential components in ducted ventilation systems, designed to prevent unwanted reverse airflow when ventilation equipment is not in use. Installed in-line with ducting or adjacent to exhaust fans, these shutters automatically close when the fan is off, protecting indoor spaces from cold drafts, outside air infiltration, insects, and dust.

At Vent Experts, we offer a reliable range of backdraft shutters suited for residential, commercial, and sub-floor ventilation systems. Manufactured from durable materials such as aluminium or galvanised steel, these shutters are built to withstand Australian conditions while maintaining minimal pressure drop across the system. They are compatible with a wide range of fan and duct sizes, ensuring easy integration into both new and existing setups.

Incorporating a backdraft shutter enhances the performance and efficiency of any ventilation system. By stopping reverse air movement, these shutters help maintain indoor temperature stability and improve overall system hygiene. They are commonly used in conjunction with ventilation supplies such as inline fans, flexible ducting, and grilles across a wide variety of airflow applications.

Whether you're upgrading an existing system or installing a new one, Vent Experts provides dependable backdraft shutter solutions to support effective, energy-efficient ventilation. Our product range caters to both DIY users and HVAC professionals seeking performance-focused accessories.
