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 fanblades 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 25”wg.
The airflow fan maintains the temperature up to 1000°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 – 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 air foilfan 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.
