    摘要: A blower includes an electric motor case, a housing having a housing inlet and a housing outlet between which is defined a flow path for gas, a first impeller adapted to accelerate gas tangentially and to direct it radially outward, and a stationary portion. The stationary portion includes an annular gas flow path of sufficient width to allow a flow of gas therethrough without introducing excessive pressure drop. The stationary portion includes a first stator vane structure defining a plurality of stator vane leading edges, the first stator vane structure located on the second side of the motor and arranged to smoothly direct gas flow along a curved path. The motor case provides a shielding function for the stator vane leading edges from an impeller blade pressure pulse.

    摘要: A blower includes a fan that causes momentum to air by rotation, a shaft that defines a rotation axis of the fan, a bearing that supports the shaft outside of the fan, and a weight that is movable in a direction of rotation of the fan. In the fan, the weight is located opposite to the bearing with respect to an end of the fan adjacent to the bearing, and thus an increase in weight by the weight can be reduced.

    摘要: Exhaust apparatus for exhausting “dirty” exhaust gases accept a core flow of such exhaust gases and combine that with an annularly-surrounding “rooftop” flow of ambient air for diluting the exhaust gases as well as expelling the diluted flow in a forcibly expelled plume in order to ensure that the “effective” expulsion distance of the expelled diluted flow is at least the physical length of the exhaust apparatus plus the gains gotten from efflux velocity and flowrate.

    摘要: A blower includes an electric motor having a shaft, a housing having an inlet and outlet between which is defined a gas flow path, the outlet structured to direct gas exiting the blower in an axial first direction, a first impeller attached to the shaft and adapted to accelerate air tangentially and direct it radially outward, a stationary portion, and a shield. The stationary portion includes a first stator vane structure defining a plurality of stator vane leading edges and a stator vane outer radial edge. The first stator vane structure is arranged to direct gas flow along a curved path that directs flow at an inner end thereof in a radially inward direction. The shield has an outer edge extending radially beyond the outer radial edge of the first stator vane structure and is adapted to isolate the stator vane leading edges from an impeller blade pressure pulse.
