An engine blower having a centrifugal blower, an engine, and a frame for supporting the centrifugal blower.

The airflow module comprises centrifugal fan.

Provided are: a centrifugal blower having sufficient water drainage ability even if the centrifugal blower is tilted; and an air conditioner adapted for use in a vehicle and provided with the centrifugal blower.

A centrifugal blower fan wheel has extruded-aluminum airfoil blades (40).

The present invention provides an apparatus for varying, regulating, or adjusting an inlet capacity of a centrifugal blower.

In accordance with a second design option, a disk-type centrifugal impeller (206) is used, which has at least one disk (207).

A centrifugal multi-blade blower is provided with an impeller (7a) and a casing (7b) that encloses the impeller (7a).

A space efficient centrifugal blower (10) having a plenum (50) connected to the impeller inlet opening (39).

The suction pipe (84) is connected to the intake of a centrifugal blower (118) by a vacuum pipe (96).

A centrifugal blower and an air conditioner, where the blower sucks air from the direction of a rotating shaft and blows it in the direction intersecting the rotating shaft.

A direct drive, high velocity, high power centrifugal air blower.

A fan has a spiral-shaped casing in which is mounted the fan impeller consisting of a carrying disk (6) and a cover disk (7) between which are secured blades (8).

This back pressure has less of an impact on the AIRPACK blower as it is a regenerative blower and is less sensitive to this back pressure than the ASO which is a centrifugal blower.

Thus, the stopper (6) can be reliably attached to the centrifugal blower or the back stopper section.

The indoor unit microprocessor controls the centrifugal blower motor through the first motor control interface unit.
