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

Know the Risk

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
