Design
and development:
CAD methods have been employed in designing our
FRP fans by the Scientists / Engineering Institutions.
We have selected optimum Aerofoil Section Thickness
in the region of 12 % to 15 % to achieve maximum
drag coefficient. Due consideration has been given
in the Aerofoil Selection. Twist is so designed
that the blade sections are maintained at the most
efficient angle of attack which is the angle having
the highest lift - drag ratio.

Light
and Strong :
Manufactured by specially developed process, the
blades are hollow, consequently they are light yet
strong and fatigue resistant. Strength to weight
ratio of FRP being very high compared to conventional
materials such as aluminum, steel and wood.

Dynamic
Balancing:
The fans are dynamically balanced on Micro Processor
Controlled hard bearing Dynamic Balancing Machine.

Quality
Control:
Composite Blades are made under strict supervision
of qualified and experienced personal. The raw materials
being used by us conforms to accepted international
Standards.
