The air foil fans are created and designed for moving the high volumes of clean air at low to medium kind of static temperature. Since 1975, it has been used for its promising performance and low energy consumption. The air foil fan blades are inclined backwards and they are created by using the same aerodynamic principals which are used to make an aircraft. The airfoil fans are among the competent centrifugal fans and put forward multiple utilities. These fan blades are also designed meticulously and provide a higher performance at a much lesser horse power. The operational sound produced by these fans is also quite low as compared to other fans. The energy cost requirement to run airflow fans is also very less. Performance and design of Air foil fan: The air foil fan blades are available in multiple sizes, construction categories, arrangements, housing widths and impellers. Air foil fans can handle the air volumes up to 350,000 cfm and the static pressure managed by these fans are 25â€wg. The airflow fan maintains the temperature up to 1000Â°F with very high static efficiency up to 80%. The designs of the blade of the fan has non-overloading power curve. The design of the fan follows the aerodynamic profile and these are twisted and tapered to generate the higher competence in its performance. Sometimes designs can also be customised and modified to meet any specific presentation requirement. The airfoil fan tenders 10 â€“ 40% power savings as compared to other GRP or metallic fans. In any newly constructed equipment these fans can help in saving the operational and equipment cost. These fans are light weight and easy to handle. These are corrosion free and vibration free fans which are highly durable in their design. Enhanced Blade Design: The airfoil fan blades are made using specially designed moulds. Blades with camber characteristics and high twist designs are created by using expensive tools and customised manufacturing process. These fans are generated by making use of advanced vacuum infusion technology which offers uniform wall thickness and weight along the blades. The vacuum infusion technology can prevent inconsistencies in fan designs like dimensional instability and manufacturing tolerance. This technology recommends enhance fibre to resin ratio and uniform wall thickness for the blade. Blade weight is kept lower which increases the blade strength. The fibre and resin properties are maximised by using vacuum infusion technology and it also presents greater aerodynamic accuracy and superior surface finish for the blades. The airfoil fan is designed to offer trouble-free performance with higher efficiency. It is also simple to install and gives effective performance. These fans can work and perform for years without the need of maintenance or any type of repair.
