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 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.
