DV350LP: New Hi Flow Rangehood Vent Kit Available.
DV350LP Hi-Flow Rangehood / Bathroom Exhaust Roof Vent
If You’ve Got a New Rangehood and a Tin Roof — This Is the One You Need.
Protect your kitchen, bathroom, and ceiling with the DV350LP — the only Australian-made, bushfire-certified, solar-ready roof vent designed specifically for tin roofs. Installs in minutes. Looks better. Lasts decades.
Generic mushroom vents are imported, non-conforming and restrict airflow. DV350LP is Australian-made, certified and leak-proof by design.
Leak-Proof • Bushfire-Safe • Certified
Old mushroom vents leak, rust and restrict airflow — most are cheap imports that don’t meet Australian standards. The DV350LP Hi-Flow Vent replaces them with a certified, triple-sealed system that keeps rain, wind and pests out — permanently.
- Sealed mounting plate & overlapping vent body
- One-way valve stops back-drafts and insects
- CSIRO tested & NCC 2025 compliant

The Problem with Generic Imported Vents
Most “mushroom-style” roof vents sold online or bundled with rangehoods are non-conforming imported products that have never been tested to Australian standards (AS3959 / NCC 2025).
- Leak around poorly sealed collars
- Thin galvanised pipe + aluminium cap — fast corrosion
- Airflow restricted by “ember mesh” — up to 35% loss
- Cause back-pressure → noisy rangehoods & trapped fumes
- Risk voiding appliance warranty due to non-compliant airflow
