DUROTUFF^TM For making the requirements of our customers fulfilled sufficiently, we are working in industry with some aspiration and thus we have Aluminum/SS turbo ventilator in our product catalog. Designed ergonomically with the use of best grade stainless steel or aluminum, offered range ensures long working life with noiseless working. With the relatively negligible use of power on operation, it is now the most efficient product in its segment. It is light in weight and can rotate with or without air. Quick cooling and complete ventilation can be availed through the installation of this Aluminum/SS turbo ventilator. Sturdy fabrication of aluminum is done and designed so as to make it adjustable on roofs with different angles.

DUROTUFF^TMFeatures:

• No electricity required for operation only natural wind
• Easy to install on any type of shed corrugation
• Light in weight
• Venturi type dome helps in reduction of lighting load
• No noise
• Maintenance free
• Dynamically balanced for friction less rotation at lowest wind velocity
• Wind, rain and storm proof (up tp 100 km/hr wind velocity)

DUROTUFF^TM With the optimum use of Polypropylene and Stainless steel, we have crafted and designed a special range of SS/PP turbo ventilators for industrial and commercial ventilation needs to be fulfilled. The high density of Stainless steel (as compared to that of aluminum) makes ventilators strong and durable. It also provides light weight to SS/PP turbo ventilator than aluminum.

This ventilator has less blades but the special designing of blades helps in providing outstanding performance. Also, the design of the ventilator prevent water from coming inside. Additionally its full SS and PP based structure makes it rust free. Its rotation system is based on ball bearing instead on bush system. These balls help in making it smooth, speedy and noiseless.

DUROTUFF^TMFeatures:

• DUROVENT ventilators are made from Polypropylene and Stainless Steel. Stainless Steel being harder material as compared to Aluminum, makes DUROVENT ventilators strong, sturdy and durable
• DUROVENT ventilators are lighter in weight as compared to any other ventilator, though SS has higher density than Aluminum. This is because of less numbers of blades, but the unique design of blades increases its overall performance
• DUROVENT Ventilators Top Fan Vanes are bi-fold which makes it strong and sturdy
• This bi-fold design of DUROVENT Ventilator vanes prevents water to enter inside the shed
• There are only 24 vanes compared to traditional Aluminum Ventilator having 36 to 48 vanes. In fact less number of Vanes allows more air to go out making natural ventilation faster.
• Rivet and other components of DUROVENT ventilators are of Stainless Steel / PP which are life time rust free
• DUROVENT Ventilators runs on ball bearing System and not Pivot (Bush) system making it more smooth, speedy, noise free and long lasting
• DUROVENT Turbo ventilators are available with Polycarbonate Base Plate.

DUROTUFF^TM Polycarbonate base plates are used to fix Turbo Ventilators on roofs. We can manufacture these base plates in matching to all roofing profiles. We are the manufacturers who can make these base plates in customized profile for our clients. We have in-house mould design and mould making facility. So we have served faster in case of customized requirement. The polycarbonate serves as an excellent replacement for FRP.

DUROTUFF^TMAdvantages

• It gives more the life than FRP base Plates. We provide 10 years limited warranty.
• Virtually Unbreakable and Design Freedom.
• UV stabilized & Temperature resistant (-40C to +130 C). Compared to FRP, PC base plates have minimal thermal expansion and contraction, which prevents cracks in long run.
• Light Transmission - PC Base plate stable Transmits light up to 85% for long time. FRP transmit up to 60% light, and it will be reduced day by day.
• Maintenance free, PC base plate dose not retain Dust it is looking clean and hygienic. FRP has retain Dust and Become dirty after some time.
• Our expertise in roofing products enables us to design base plates matching with Metal sheet precision, thus eliminating the possibility of leakage.
