PROBLEM TO BE SOLVED: To prevent gas leakage from a plurality of air ducts arranged in series with their ends releasably connected to each other while preventing disassembling difficulty of the air ducts. SOLUTION: A blower facility includes the plurality of air ducts arranged in series with their ends releasably connected to each other in which gas inside the air ducts can flow to the outside of the air ducts via connecting portions of the air ducts, and the gas leakage prevention material comprising a sheet having no air permeability wrapped around ends of two adjacent air ducts by covering the connecting portion. Both ends of the sheet in the direction to wrap the axis of the air duct are releasably coupled to each other by a coupling means. COPYRIGHT: (C)2009,JPO&INPIT |
