TECHNICAL INFORMATION OF INDUSTRIAL ROOF VENTILATORS |
 |
| Superiority of Industrial Roof Ventilation Systems |
The Tornado features such superior qualities as  Tested extraction capacity - report available on request Comprehensive 5 year guarantee 100% South African product Patented Bearing system Top quality of manufacture Superior internal design of the Tornado eliminates the necessity of external supporting braces Larger rotating dome for increased extraction capacity Sealed bearings enclosed in a sealed bearing housing. |
| Components |
|
Dome - vertical mounted blades specially formed to prevent water and dust penetration. |
|
Shaft - yellow cadium plated bright mild steel. |
|
Bearing System - unique and patented type ZZ lubricated bearings in a reinforced housing to prevent from corrosion. |
|
Cylindrical throat - two piece elbow type that will fit most inclined roof tops. |
|
Base plate - ensures water and dust proof attachment to the roof. |
|
|
| Material Type |
The Tornado Turbine is available in a choice of Galvanised and Aluminium material.
Galvanised Tornados are constructed of Iscor specification Z275-0,6mm 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 Tornados are recommended for the ventilation of acid and caustic fumes intensive plants to protect the material from corrosion.
