RAINBOW VENTILATORS Some of the advantages of the Turbo Ventilator are:
� Relative inexpensive methodology for ventilation as compared to ridge ventilators or Electrically operated ventilators.
� No running cost since it is operated by natural wind power. � No need of electricity. � Available in Aluminum and Stainless Steel material. � 10years warranty on the product.
Rainbow Ventilators is a new
concept in the Wind Operated Turbo Ventilators. This is a new product for use in proper ventilation of pitched roof construction including industrial sheds, commercial buildings, farm houses etc. This product is a Wind operated Ventilator installed on the roof and is rotated by the Wind, the stale air inside is exhausted through the vanes and a natural
inward flow of fresh air is boosted. We are the pioneers in Wind driven ventilation in Northern India. Turbine Air Ventilator works without electricity, it runs on wind velocity and it works 24 hours a day and 365 days a year, it doesn’t require any kind of maintenance once installed and there are no accidents like fire due to short circuit/ shocks.
� No maintenance required.
� Can be easily fitted on Asbestos, Corrugated Asbestos, Galvanized Iron and Aluminum roofing.
� The product is allowed 80% depreciation as per IT rules.
Features
It has a fool proof Bearing Mechanism
It has a Dust proof Individual Bearing Housing For Protecting Sealed Bearings.
It is Completely Enclosed & Dust Proof Integrated Bearing Housing.
The Bearings are Aligned with each other due to the integrated housing
Rotation at nearly zero wind speeds due to aligned bearings
Static Balancing
Suitable for all roof heights between 15 ~ 100 feets
Suitable for dusty/smoky/oily/harsh conditions
NIL Exhaust problem due to air back draft
Ventilator material available in Aluminium and Stainless Steel
Hardware Material available in Stainless Steel
Vanes specially formed to deflect rain and any other water
Trouble free and smooth operation even at low wind velocities
These ventilators are manufactured in high-grade Aluminium including the rivets and
therefore fully free of atmospheric corrosion.
These ventilators are light in weight and low operational at very light wind speeds.

Rainbow Turbo Ventilators and Conventional Ventilators
Rainbow Turbo Ventilator Conventional Ventilators
Non-conventional energy saving system Conventional energy system
No electricity bills. Cost of ventilator is recovered in the
first year itself.
Electricity bills are a monthly feature. Increasing cost of
electricity makes electrically operated-ventilator a costly
proposition.
There are no accident hazards
Prone to accidents like electrical short circuits & shocks
which could be fatal and losses due to fire accidents could
be catastrophic.
Operation is free of rodent menace Rodents can damage electrical wiring resulting in stoppage
of ventilation systems.
Can be installed in any place where natural wind is
available.
Can be installed in only those places where electricity is
available
Operates on natural wind available Requires electrical energy at rated voltage.
Can operate at varying velocities. Any fluctuations in
wind velocity affect air discharge, marginally without any
damage to ventilator.
Requires rated electricity. Any fluctuation in voltage &
amperage may damage the components of electrically
operated system.
Assured operation for 24 hours a day, 365 days a year Can operate only when power supply is available
Do not require any wiring switching and person to
operate
Require necessary wiring, switchboards, and persons to
operate
No maintenance costs as there are any armatures / field
coils / switches.
Maintenance required due to the presence of armature,
field coil, switches, carbon brushes etc.
Ventilators help to alleviate the buildup of summer heat in roofs, contributing toward reducing the cost of energy for cooling. In winter vents eradicate buildup of moisture in roof cavities that may contribute to a variety of structural problems. In industry applications, ventilators improve the working environment by increasing air circulation.
Turbine ventilator is a natural, economical and effective way for exhaust of air round the clock without power or operating costs. An energy saver for a better tomorrow Turbine ventilator totally operates by non-conventional method of exhaust system. Its method of operation is different from the conventional method of exhausts such as motorized exhaust fans and passive ventilation systems like jack-roofs and ridge.
The turbine ventilator operates by utilizing the velocity energy of the wind to induce airflow by centrifugal action. The centrifugal force caused by the spinning vanes creates a region of low-pressure area, which draws air out through the turbine ventilator. Air drawn out by the turbine exhaust is continuously replaces by fresh air from the outside. The slightest breeze will cause the turbine ventilator to spin and even after the breeze has stopped, the flywheel effect of the rotor cage will use its stored energy to continuously remove air. Suction is maintained even at low wind velocities.
