Claims

[Scope of utility model registration request]

The interior is divided vertically except for the part where the impeller passes through the partition wall, and has two opposing suction ports and two closely aligned C7 discharge ports, and has a single rectangular cross section as a whole, with a spiral surface. a casing, a driving single-shaft motor whose rotating shaft extends through the bulkhead from one suction port of the casing to the other suction port, and a motor that is attached to the rotating shaft of the single-shaft motor and that is mounted on both sides of the bulkhead. It consists of a single impeller having a plurality of blades lined up and a flange that protrudes from the center of the outer periphery and faces close to one side of the partition wall, and the opposing surfaces of the flange and the partition wall are in a non-contact state. A blower with a ring-shaped protrusion that engages in a staggered manner and bends the gap between the flange and the partition wall into a crank shape.
