A seating assembly includes a seatback having a seatback cushion. A carrier supports the seatback cushion. An upper thoracic region includes a first side support defining a first receiving aperture and a second side support defining a second receiving aperture. A lower lumber region includes an actuatable lumbar support configured to move between deployed and non-deployed conditions. An air mover is disposed between the first and second side supports. The air mover is suspended between the first and second side supports by a flexible band that extends laterally between the first and second side supports and is removably coupled with the first and second receiving apertures.

An attachment structure enabling more efficient work in performing maintenance of a fan of a fan unit and a more stable electrical connection between a main body of an electrical equipment and a fan unit. An attachment structure configured to detachably attach a fan unit including a fan and a casing housing the fan to/from a main body of an electrical equipment includes a guide mechanism configured to guide a slide motion of sliding the casing in one direction relative to the main body to dispose the casing at a mounting position, and a retaining mechanism configured to restrict movement of the casing relative to the main body in a direction opposite the one direction when the casing is disposed at the mounting position by the slide motion.

A blade row group arrangeable in a main flow path of a fluid-flow machine and including N adjacent member blade rows firmly arranged relative to one another in both the axial direction and the circumferential direction is provided. Here, a front member blade row with front blades as well as a rear member blade row with rear blades are provided in the meridional plane established by the axial direction and the radial direction. The blade row group has two main flow path boundaries. It is provided that the blades of the member blade rows are fixed to the one main flow path boundary in the surrounding structure by means of a blade root structure, and that the blades of the member blade rows on the other main flow path boundary are each firmly connected to a base.

A ventilation fan assembly suitable for installation in a ceiling or wall to provide ventilation of the adjoining space, wherein the ventilation assembly includes a fan housing and a removable flange mounting system. The flange system including at least one bracket with a receiver that removably engages an extent of the lower housing edge and a flange that extends from the receiver outward from the lower housing edge. Depending upon the positional relationship of the fan housing and the support surface(s), namely the ceiling, the flange engages an extent of a lower or upper surface of the ceiling. The bracket receiver includes at least one projection that is engages a corresponding aperture formed in the lower housing edge to removably couple the bracket to the housing. The removable flange mounting system improves the installation process and/or the sealing performance of the ventilation fan assembly.

Notched portions and positioning projecting portions are elastically engaged with each other to hold a fan unit at a fixing position in a housing, in a state in which the fan unit is placed at the fixing position.

This invention relates in general to a device for controlling the flow of a fluid. The device having a plurality of motor assemblies mounted at equidistant points around a mounting collar. An elongated annular outer casing surrounds and is spaced outwardly from the motor assemblies and defines with the motor assemblies an annular air passage. The outer casing having a central longitudinal axis, an open forward end for receiving ambient air and an open rear end for discharging air forced fluid. The device has a supporting structure on which the outer casing is mounted and a fluid flow assembly. A turntable is coupled to the supporting structure for rotation and an actuating assembly is used for raising and lowering the outer casing, wherein the actuating assembly is coupled between the supporting structure and outer surface of the outer casing.

A modular fan array includes a fan assembly having a fan wheel, a fan motor, and a mounting bracket. The fan wheel has a diameter. The assembly includes a frame having at least a pair of vertical members having a spacing therebetween. The spacing is greater than the fan wheel diameter. The mounting bracket includes a motor mount portion and a pair of rearwardly and outwardly extending legs. The motor mount portion includes an opening in which the motor is mounted. The rearwardly and outwardly extending legs each have a first angled section angled relative to the motor mount portion and second frame mount portion. The frame mount portions extend outwardly from the angled portions and parallel to the motor mount portion. The frame mount portions are removably secured to the frame.

A blower includes a housing including an inlet and an outlet, a stationary component provided to the housing, an impeller positioned between the inlet of the housing and the stationary component, and a motor adapted to drive the impeller. The stationary component includes a tube portion structured to retain and align a pair of bearings that rotatably support a rotor to which the impeller is coupled. The tube portion includes a diameter in a side closest to the impeller that is sufficient size to accommodate adhesive to retain one of the bearings.

A fan assembly comprises first and second fans and a first press fit stabilizer. The first and second fans comprise housings having a plurality of fastener apertures formed in a first side thereof the first housing. The first press fit stabilizer comprises a plurality of press fit tabs. The first fan is coupled to the second fan via a first press fit tab of the plurality of press fit tabs inserted into a first fastener aperture of the plurality of fastener apertures of the first housing and via a second press fit tab of the plurality of press fit tabs inserted into a first fastener aperture of the plurality of fastener apertures of the second housing.
