Abstract
The present invention provides an air filtration device attachable to a motor. The device comprises a housing comprising an upper part and a lower part, wherein the upper and lower parts are parallel and spaced apart from each other and define a cavity therebetween, and wherein the lower part has a centrally positioned opening therein; an impeller positioned coaxially with the axis of the housing between the upper and lower parts thereof and attached to the motor; and a filter positioned between the upper and lower parts and positioned around a perimeter of the housing.
Claims39
An air filtration device comprising:
- a housing comprising a non-air communicating upper surface part and a lower part, wherein the upper and lower parts are parallel and spaced apart from each other and define a cavity therebetween, wherein the lower part has a centrally positioned opening therein, and, wherein the upper part of the housing is suspended from, or flush mounted to a supporting surface;
- a rotary motor having a rotating shaft which defines an axis of rotation, wherein the motor is positioned such that the axis of rotation is co-linear with an axis of the housing;
- an impeller positioned in the cavity coaxially with the axis of the motor and attached to the motor, said impeller having a plurality of blades that curve away from the direction of rotation;
- a filter positioned between the upper and lower parts and positioned around a perimeter of the cavity;
- and
- a lighting fixture attached to the lower part of the housing, said fixture providing for positioning of a light emitting element therein, and directing unfiltered airflow away from, and not towards and over the light emitting element.
