The Tornado 610mm whirlybird series of roof ventilators are South African designed and manufactured. This product is a cost effective and energy efficient solution to ventilate factories, workshops, warehouses, agricultural properties, schools and learning centres, hostels, residential homes, assembly halls and other buildings and structures that require air ventilation. One of the primary abilities the wind turbines have is to remove dust penetration and those unwanted down-draughts that blow into a building. They ensure a much healthier and cleaner working environment for everyone.

610mm whirlybird Keeping it cool

Natural convection from inside the building as well as the wind from outside is what drives the turbines. It enables the whirlybird to spin creating a pump like action, drawing out the stale air. The tornado vent has enhanced extraction which is created by a flow of air through the throat of the ventilator. there have been reports of increased productivity and even reduced stress because the turbine creates a healthier working environment.

What exactly does the 610mm whirlybird do? When the turbine rotates it starts to remove the convected heat from within your building and increases fresh air flow. This action produces an effective cooling effect on the people working in the building and the environment in the building as well.

Superior roof ventilation system

Features of the 610mm whirlybird Tornado wind turbine:

  • The extraction capacity has been thoroughly tested
  • Tornado has Comprehensive 5 year manufacturer guarantee
  • 100% manufactured in South Africa
  • Special patented bearing system for noiseless operation
  • Manufactured from top quality parts
  • Compact design takes away unnecessary supporting braces.
  • The extraction capacity is increase because of a larger rotating dome.
  • The bearings have been sealed in an enclosed bearing housing.

Components of the 610mm whirlybird

  1. Dome – vertical mounted blades specially formed to prevent water and dust penetration.
  2. Shaft – yellow cadium plated bright mild steel.
  3. Bearing System – unique and patented type ZZ lubricated bearings in a reinforced housing to prevent from corrosion.
  4. Cylindrical throat – two piece elbow type that will fit most inclined roof tops.
  5. Base plate – ensures water and dust proof attachment to the roof.

Material type

The Tornado 610mm whirlybird is available in a choice of Galvanised and Aluminium material. Additionally, galvanised Tornados are constructed of Mital specification Z 275 – 0,6mm steel.

The structure of the galvanised unit makes it more durable and reliable in the long run in terms of:

  • high velocity wind areas, hail storms and heavy rain
  • general handling and transportation

The Aluminium Tornado is recommended for coastal areas. Polyurethane treated Tornado’s are recommended for the ventilation of acid and caustic fumes intensive plants to protect the material from corrosion.
