One of the most popular products in Airocle’s range, the rotary roof ventilators, also commonly known as “whirlybird”, offer an effective and environmentally friendly solution for commercial and industrial buildings natural ventilation requirements.
Using thermodynamic and centrifugal forces combined with innovative design, Airocle’s rotary roof ventilators use the natural up-flow of hot air to rotate the ventilator head and create a vacuum. Warm and contaminated air rushes up to fill the vacuum and is then expelled without any air funnelling back in.
Highly versatile, Airocle’s roof rotary ventilators can be used on slope, ridge, flat or curbed roofs and will fit all building roof profiles.
