Non Power Driven Stainless Steel Wind Ventilators, For Ventilation

Working Principle of Air Ventilator:

The ventilator is combination of both natural & forced ventilation system. It Functions as a natural ventilator when there is a difference in thermal or wind pressure between the inside and outside of the building which Forces the air to move through the opening of the ventilator. Industrial activity generates heat and hot air being lighter moves upwards. The lighter air get accumulated in the turbine of the Wind Ventilator. As the hot air tries to escape from the turbine, it exerts a backwards thrust on the vanes and sets them in a rotational movement . When the ventilator blades rotate the turbine it gives rise to the centrifugal force and creates a vacuum inside the turbine .The partial vacuum is replaced by strong upward forceful movement of the wind . As the hot air is thrown out, fresh air starts entering through windows and door openings .This works for a perfect exhaust by wind driven ventilator thrown out, fresh air starts entering through windows and door openings.

Key Features :

• No operating cost as it works on free wind energy.
• Globally accepted technology.
• Dual benefit of natural ventilation and natural daylight.
• Whole year round and 24 hours a day EFT
• Lightweight, strong and durable construction for resistance against extreme climate conditions
• Maintenance free "Fit and Forget"
• No Bearings used in the entire system so no need to replace bearings.
• Rigid spider type frame construction to withstand Cyclone, Storm, and Twister.
• Whisper quiet in operation.
• Easy and Quick installation on any roof profile.
• 36 Aero foil blades with groove to deflect water and dust.
• Dynamically balanced for frictionless rotation also at lowest wind velocity.
• Enhances the architectural and aesthetic appearance of the building.
• The FRP Ventura Dome used with Turbo vent provides natural light during day time thus reducing lighting load.
• Continuous positive extraction of the Turbo vent eliminates heat, dust, fume penetration and a down-draught into the building to ensure a cleaner and healthier working environment.
• Increases productivity by promoting healthier and more comfortable working environment through proper ventilation.

FRP Sheet ( Venturi Dome ): Techno tech Enterprises offers an all new concept of FRP Venturi Dome for Turbine Ventilators. These FRP Venturi Domes are made of Fiberglass chopped strand mat and Unsaturated polyester based high quality Resins with imported U.V.stabilizer as per the international standards to achieve protection against harmful U.V.Rays. Venturi Domes are available in different roof profiles and can be manufactured as per the required girth and is available in different color shades matching the color of roofing sheets and exterior of the buildings. Special features of Techno tech FRP Venturi Dome:

• Manufactured by utilizing the best quality of basic raw materials.
• Specially formulated top layer retards the effect of abrasion and erosion and enhances its life span.
• Uniform distribution of natural daylight during daytime thus reducing lighting load.
• It is lightweight and hence saves the structural cost and erection cost.
• Durable & fire retardant,
• Protection from corrosion, leakages, rust and prevents warping.
• FRP Venturi Dome is the best and most economical solution for M.S./S.S./Galvanized Steel Domes.
