Abstract (en)
The invention relates to a fan assembly (10). The fan assembly (10) comprises a volute casing (1) with a volute tongue (16); a rotor (2) mounted in the volute casing (1) and rotatable around a rotor axis (23); and a cover (3) fixed to the volute casing (1) and defining an inlet opening (31) therein. The rotor axis (23) is closer to the volute tongue (16) than an axis (311) of the inlet opening (31). The fan assembly (10) can provide higher air pressure and higher air flow under the same noise level, or provide lower noise under the same air flow and air pressure.
