Alpine Ventilation Gravity Vent with Mesh — Durable Roof and Duct Ventilation Solution

SKU: GAV100

BTS: Loading...

Ensure effective, draft-free ventilation with these high-performance gravity vents featuring integrated mesh protection. Designed for external wall installation, they automatically open when air is being extracted and close when the fan stops—helping prevent backdrafts, heat loss, and unwanted outdoor air entering your home.

Manufactured from UV-stabilised polypropylene, these vents are built to withstand harsh weather conditions and long-term sun exposure, making them ideal for residential and light commercial applications. The built-in steel mesh provides reliable pest control and added debris protection, while also supporting BAL bushfire compliance when installed as part of an appropriate system.

Perfect for a wide range of exhaust and ventilation setups, these gravity vents are commonly used with:

  • Clothes dryers
  • Kitchen rangehoods
  • Bathroom exhaust fans
  • General room and whole-house ventilation systems

The simple, moving-louvre design has no electronics or complex parts, delivering quiet, low-maintenance performance. When the connected fan operates, air pressure gently pushes the louvres open for efficient airflow; when the fan switches off, the louvres close to help keep insects, drafts, and rain out.

Choose these gravity vents as a durable, low-profile solution to enhance indoor air quality, improve energy efficiency, and protect your home from pests and weather while maintaining a clean, discreet exterior finish.
