Zusammenfassung:	An impeller (16) includes a hub (32) and a plurality of blades (30). Each blade (30) extends out from the hub (32). The impeller (16) has an original diameter defined by respective tips (38) of the plurality of blades (30). Each blade (30) includes a central axis (140), a leading edge (150), a trailing edge (152), an original profile (132), and a plurality of trim profiles (134, 136). The original profile (132) has an outside portion and a trailing portion (138). The outside portion has an angle within a range of about 40° to about 90° from the central axis (140) and the trailing portion having an angle within a range of about 10° to about 50° from the central axis (140). A first selected trim profile (134) of the plurality of trim profiles (134) extends along a first line parallel to the outside portion and a second line parallel to the trailing portion.
