<p><P>PROBLEM TO BE SOLVED: To solve the problem that the maintainability of a belt, an inverter and a plurality of fan units in a narrow space under the roof becomes poor, in case a rotating speed of a bladed wheel is increased by belt driving, the rotating speed of the bladed wheel is increased by inverter control, or the two fan units are horizontally arranged in one machine body, when largely increasing the air volume in a conventional air blower with a sound absorbing box. <P>SOLUTION: This air blower with the sound absorbing box is constituted by superposing two machine body assemblies 11-1 and 11-2 each having a centrifugal air blower 10 while interposing a space 20 between the two machine body assemblies, and connecting the two machine body assemblies 11-1 and 11-2 via a machine body suction port adapter 21 and a machine body blowout port adapter 22 for blowing air by integrally merging machine body openings of the respective machine body assemblies 11-1 and 11-2, and thereby noise can be reduced while improving workability and maintainability by preventing a vibration propagating phenomenon while securing connecting strength. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
