    Whirlybird Ventilators

    Whirlybird Ventilation

    The Whirlybird is a wind driven ventilator that removes hot stale air from buildings, causing a low pressure that allows fresh air back in via doors and windows. The first solution for cooling down your environment. Turbine ventilators keep indoor environments cooler and healthier. They use no electricity and turn using only wind and convection.

    General features:

    • Can be fitted to almost any roof up to a 32° pitch
    • Requires no maintenance
    • Are completely silent
    • Are waterproof
    • Keep dust and pollutants from coming into the building
    • Are SABS approved
    • Can be used in confined spaces such as containers
    • Can be used to enhance the effectiveness of chimney flues.


    • Cooling and ventilation – the primary benefit of turbine ventilators is that they efficiently remove hot, stale and polluted air from buildings
    • Cost effective as they require no running costs or maintenance
    • In winter, ventilation removes moisture-laden air which causes structural damage and mould to grow
    • Reducing the building’s heat load will assist in reducing air conditioning bills in summer.
    • The steady flow of air through ventilation clears out airborne contaminants and replenishes oxygen levels in the air, creating a fresh, clean environment.
