All External Air Vents

Browse external ventilation grilles and terminals for connecting ducted ventilation systems to the outside of the building.

External vents are available in different sizes and configurations for fresh-air intake and exhaust applications and should be selected to suit the duct size and required airflow.

Frequently Asked Questions

  • What size external vent should I use with my ducting?

    The vent connection should match or be correctly adapted to the duct size and provide enough free area for the required airflow without creating excessive resistance.

  • Do external ventilation grilles need cleaning?

    Yes, external vents should be inspected periodically and cleared of leaves, dirt, insects or other debris that could restrict airflow.

  • Can an external ventilation vent be installed in a soffit instead of a wall?

    Some terminals are suitable for soffit installation, but this depends on the product and ventilation design. Intake and exhaust positions must also minimise the risk of air recirculation.
