Centrifugal fan with airfoil blades
Févi international
AND ONLY SLIGHTLY CLOGGING DUST
Because of the aircraft wing profile shape of the blades, the fluid is discharged with
a minimum of turbulence, shocks and loss in the impeller, with as a result silent
operation, low input power and a high efficiency.
As each blade forms a box beam which can be stiffened on the inside, a airfoil
bladed impeller is mechanically very strong and allows for very high operating
speeds.
This blade is particularly well suited for wide impellers both from an aeraulic
and mechanical point of view.
This blade is generally used for clean gas but is also suitable for gas charged
with dust even if clogging, except for the C14 family.
It is not suitable for gas charged with abrasive dust.
