SKU: N/A Categories: ,


The DV-280-T Hi Flow exhaust roof vent is suitable for corrugated tin roof applications and installed with kitchen, BBQ rangehoods and ceiling exhaust fans. With a much lower profile these vents are a popular choice when building any home and can also be used in Category D cyclone regions and bushfire regions (BAL 12.5 to BAL 40 and BAL FZ for steel frame homes).

Great for roofs with solar panels as unlike the old style ‘mushroom’ roof vents the DV-280 won’t stain your solar panels with house hold effluents (i.e. cooking fat molecules, lint…etc). Testing has shown that these pollutants can reduce solar efficacy by up to 15%.

The slim line design makes this vent both architecturally and aesthetically aligned with modern home values and design requirements. The DV-280 is also recognised as the go-to vent for those building green star efficient homes with the added feature of an internal non-return gate which stops any back draft entering the home. The Ember mesh will also stop the egress of flies and unwanted rodents into a home via roof venting.
