Wheel
Forward curved centrifugal impellers, tablocked on both sides to two stell rings and double
disk at the center.
The blade has been designed to minimize the loss caused y the air
turbulence and to achieve the minium sound level with the maximum effi ciency.
All wheels
are dynamically balanced.
Housing
Constructed form electro-welded sheet steel. A cut-off to prevent turbulence is mounted
on the discharge side.
The side plates are provided with inlet and drill holes for fi xing the

The RTC models are manufactured using standard
fan and adding rectangular structure built with “L” profi les. This frame is spot-welded
to the fan and strengthens the unit.
