PROBLEM TO BE SOLVED: To provide a long fan with reduced cost and noise and with high hydrostatic pressure. SOLUTION: The long centrifugal fan comprises: a plurality of multiblade impellers coaxially journaled to a rotational shaft; a casing housing all of the plurality of multiblade impellers; and a motor rotating the plurality of multiblade impellers. A plurality of partition plates are disposed inside the casing orthogonally to a longitudinal direction of the casing to partition the inside of the casing into fan chambers and intake chambers. Each fan chamber functions as a centrifugal fan. COPYRIGHT: (C)2006,JPO&NCIPI
