RB
DESIGN
For the first time in the history
of fan engineering, our designers came out with
a 'Ribbed Blade' design - a blade with a recessed
central rib. This new design cuts air resistance
for noiseless and uniform air dispersal.
The design provided added structural strength
to the blade, preventing distortion of the aerodynamic
design during normal functioning and while cleaning
in assembled condition.

DTA
BLADE
A further innovation was to split
the twist in the carrier with that on the blade.The
combination created the double twist angle
(DTA) which led to optimum design throughout
the studies of incremental variations. Fans normally
develop a "tunnel" corresponding to
its sweep and the breeze thus generated does not
reach a person outside its periphery.
The DTA blades, coupled with an increased lift
angle break through the air tunnel and disperse
air to every corner of the room.

MAXI-TORQUE
MOTOR
Orient designers did not stop
at the blades and the carrier. Through a process
of backward integration they have brought many
other improvements which cumulatively add up to
a lot. For the core of the fan - the rotor, the
stator assembly, electrical stampings - were fabricated
from energy efficient electrical steel. The end
result is improved torque, which in turn leads
to better utilization of power and lower electricity
bills. Every optimum blade loading has been matched
with a selective load condition of the motor during
its designing.

AUTO-SPEED
RETENTION
Further innovation in the motor
created the anti fluctuation speed-voltage charateristics.
This acts as a stabiliser in the fan, ensuring
sustained air flow even under fluctuating voltage
conditions.
