    How it works

    Wind-tracking extraction without electrical power

    The SharkVent™ uses a 360-degree wind-tracking hood to remain aligned with the prevailing wind direction.

    Its fin-shaped hood and venturi-enhanced design support passive air extraction while helping reduce backdrafts and weather ingress.

    A counterweight mechanism helps maintain alignment with changing wind direction and limits overspinning during gusty conditions.

    Durability

    Designed for exposed outdoor environments

    • Wind-powered operation with no electrical supply required.
    • Operates when useful wind is available rather than spinning continuously.
    • UV-stabilised and corrosion-resistant external materials.
    • Designed for exposure to high UV, hail and strong winds.
    • Integrated barrier helps prevent birds, rodents and debris entering the vent.
    • 316 stainless-steel bearings, shaft and fasteners.
    Applications

    Suitable ventilation uses

    • Composting toilet ventilation and odour control.
    • Sewer and wastewater venting.
    • Bathroom ventilation for humidity and odour removal.
    • Roof-space ventilation for heat and moisture management.
