Why the DV-350LP Is Changing Roof Ventilation in Australia

At Dragon Vents Australia, we designed the DV-350LP Low-Profile Roof Vent to solve the real problems builders face: airflow, compliance, and space for solar. The result? A vent that’s as tough as the Australian climate and as sleek as today’s modern homes.

Built for Modern Roofs

At only 60 mm high, the DV-350LP sits flush with the roofline and allows solar panels to be installed directly over it. No more bulky “mushroom” vents eating up valuable roof space or spoiling the look of a new home.

Certified for Safety

CSIRO-certified to AS3959 (BAL 12.5–40), cyclone-rated, and fitted with ember, insect and vermin protection, the DV-350LP meets the strictest building codes while keeping homes safer.

High-Flow Performance 

With airflow tested up to 1,030 m³/h, this vent outperforms standard builder vents by a wide margin—delivering quieter, more efficient rangehood and bathroom exhaust systems.

Easy for Builders

Designed for roof pitches from 15°–35°, the DV-350LP is simple to install, trade-friendly, and backed by local stock in Colorbond® and Zincalume finishes.

The Smarter Choice for Australian Homes

For builders, architects, and homeowners, the DV-350LP is more than a vent—it’s a future-ready solution that combines performance, compliance, and design freedom.
