An alignment guide assists with positioning of the air mover with respect to a room wall to enhance air flow within the room. A cord retaining system provides an enhanced approach for securing the air mover's electrical cord. Grill guards have slotted ends to assist with assembly of the air mover.

  • Publication number: 20150147170
    Abstract: The invention relates to a modular fan unit of a diagonal and/or axial fan. According to the invention, the modular fan unit has a housing that has been provided with an inlet opening and an outflow opening. The housing accommodates a fan, whereby the fan can be an axial fan or a radial fan. In any case, the fan conveys the air at least in the axial direction. The housing is divided perpendicularly to the middle axis (X-X) of the fan into at least two housing halves that are joined to each other, namely, the motor holding part and the air inlet part. The housing forms a chamber in which the blades of the fan are accommodated so as to rotate around the axis (X-X) of the fan. Moreover, the housing has a circumferential edge area in the vicinity of which the housing has a thickness B extending in the axis direction (X-X) of the fan. The motor holding part has a dimension R as the maximum extension in the edge area in the axis direction (X-X) of the fan (150).
