What is a Roof Fan?

A roof fan is either an axial fan or centrifugal blower contained within a roof mounted unit that can cover a variety of applications depending upon the design of the unit. Roof fans also come in either vertical or horizontal discharge configuration.

Roof fans provide a simple way to ventilate large areas and can be used with ducting or without. Typically, axial fans are used without and provide higher volumes, whilst centrifugal fans are used with ducting and can generate higher pressures to accommodate the ducting.

Roof fans are typically used on commercial and industrial buildings such as shopping centres, warehouses and factories.
