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 the 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.
