Forefinger ® is an innovative device
fully developed and engineered
by the Aeraulic and
Acoustic Test Lab of Comefri.
The principle is to exploit
the air swirls, always
present inside a fan housing.
As well known, the recirculation
of the air streams
inside the fan housing is a
major source of losses, decreasing
the fan efficiency
and increasing fan’s noise.
This device, called Forefinger
®, is actively readdressing
this air recirculation to
the outlet, with a systematic
enhancement of the performances,
both aeraulic and
acoustic.
