    摘要： A portable ventilator having axially aligned inlet and outlet ports, an inlet fitting adapted for alternative connection to the inlet port in either of two 180.degree. reverse orientations. In one such orientation, the inlet fitting enhances air flow into the ventilator, and in the other such orientation, the inlet fitting adapts the inlet port for connection to a suction duct or the like.

    摘要： A fan assembly has a circular disc with a rotational axis and first and second sides. A cylindrical side wall extends around the periphery of the disc. The side wall has axially spaced first and second rims and is circumferentially subdivided into a plurality of wall segments, each wall segment has inner and outer surfaces, with the second rim of the wall protruding axially beyond the second side of the disc. Fan blades are carried on the outer surfaces of the side wall segments. Mounting members protrude from the first side of the disc at locations spaced circumferentially around the periphery thereof. Connecting members on the inner surfaces of the wall segments coact in separable interlocked engagement with the mounting members to fasten the wall segments to the disc. A first ring on the first side of the disc prevents the connecting members from separating from their interlocked engagement with the mounting members. A second ring on the second side of the disc interconnects the wall segments.

    摘要翻译： 风扇组件具有带有旋转轴线和第一和第二侧面的圆盘。 圆柱形侧壁围绕盘的周边延伸。 侧壁具有轴向隔开的第一和第二边缘，并且周向地细分成多个壁段，每个壁段具有内表面和外表面，其中壁的第二边缘轴向突出超过盘的第二侧。 风扇叶片承载在侧壁段的外表面上。 安装构件在盘的第一侧周围围绕其圆周间隔开的位置突出。 连接构件在壁段的内表面上与支架部件可分离地互锁接合，以将壁段紧固到盘上。 在盘的第一侧上的第一环防止连接构件与其与安装构件的互锁接合分离。 盘的第二侧上的第二个环连接壁段。
