Commercial Roof Ventilation


Ventlite Industrial Vents 530mm-610mm Vent

The 530mm and 610mm whirlybirds offered by Ventlite are specifically geared at commercial and industrial installations. These vents come with extra-large throat sizes and are able to ventilate the roof space of factories, warehouses, industrial units, office buildings and other large structures.

Ventlite has used aluminium in the construction of the industrial vents. Unlike steel vents, aluminium vents are considerably light-weight and offer far more effective ventilation. They are also anti-corrosive which makes them particularly suitable for industrial environments with corrosive fumes.

Inside both industrial models, Ventlite has used a 10mm stainless steel shaft as well as 4 riveted aluminium braces. These structural features ensure that the whirlybirds rotate in a stable and secure way over a long period.

The 530mm and 610mm models from Ventlite feature individually sealed and lubricated dual steel bearings. These enable the vents to rotate smoothly and without making any noise, making for a quiet operation. The bearings are also incredibly long-lasting and require little to no maintenance on your part.

Ventlite offers these vents in square to round base and with roof pitches that enable installation at 0 to 45 degrees. With a variable pitch, these large vents can be installed on the rooftops of most commercial and industrial buildings.

The two industrial models have been Category 2 Cyclone tested, so they are able to withstand extreme weather conditions effectively. They operate entirely in wind energy and incur zero energy costs. This makes them an environment-friendly ventilation solution for any building.
