1-1 Fan and Volute Case

Air is sucked from the whole circumference of the full cover type guard net and from the side structure of the
newly designed blow molding frame to send a lot of air to the fan. The fan uses a half-closed fan, optimizing
the air flow with the new flat volute case, realizing the very best of the air volume and wind velocity.
