Zusammenfassung:	A heat gun having a fan assembly (10) for use therein having a flow straightener (48) to reduce turbulence in air passing through the fan assemb ly (10). The fan assembly (10) also includes a blower housing (14) with a reduc ed diameter outlet (92), a relatively large diameter radial flow impeller (36), and an electric motor (10) to rotate the impeller (36). The flow straightene r (48) includes a plurality of vanes (50), and curved radially interior and exterior walls (47, 49). The motor (60) includes apertures (68, 70) in upstream and downstream ends and apertures in a cylindrical sidewall.
