A blower configured to be positioned in confined spaces and to provide ventilation of a fluid, such as temperature controlled air, is disclosed. In various embodiments, the blower is configured to have a reduced axial thickness, which can be desired in such confined spaces. In some embodiments, the blower has an integral filter, a wire channel for the routing of one or more wires, and/or an exposed backplate. In some embodiments, the blower has a snap-fit circuit board, containment system for mounting the motor, one or more vanes for directing fluid flow, shrouded impeller, and/or integrated connector.

1. A low-profile blower, comprising: a housing defining an interior space, the housing including an inlet and an outlet;wherein the housing has a first side and a second side joined by a sidewall;an electric motor assembly disposed within the interior space, the motor assembly comprising a backplate, the backplate being coupled to the housing;an impeller comprising a plurality of blades, the impeller being coupled with the motor assembly, the motor assembly configured to selectively rotate the impeller;wherein the impeller is configured to draw a fluid into the interior space of the housing via the inlet and to discharge the fluid from the interior space via the outlet;wherein the fluid proceeds through a portion of the interior space with a non-uniform velocity, the portion being in communication with the outlet;a filter disposed at least partly in the inlet such that at least some of the fluid passes through the filter, wherein the filter comprises a mesh and is integrated with the housing, wherein some of the housing is located in voids in the filter;a circuit board positioned in the interior space and below the impeller, the circuit board having an outer periphery and comprising a plurality of electronic components coupled to the circuit board;wherein the blades are axially disposed generally above the circuit board by an axial distance, the blades disposed at least partly within the outer periphery by a radial distance;at least one wire, the wire configured to supply electric power to the electric motor assembly;wherein the least one wire extends from outside the housing into the interior space;wherein at least one channel is formed in the housing, at least a portion of the channel being covered with a cover member; andwherein an exterior surface of the housing comprises a recess, the recess being configured to receive the cover member such that a surface of the cover member is generally flush with the exterior surface of the housing. 2. The blower of claim 1, wherein: the at least one channel extending at least partly between the sidewall and the circuit board;the at least one channel is configured to at least partly receive the at least one wire; andthe at least one channel is configured to axially fully receive the wire. 3. The blower of claim 1, wherein the at least one wire does not axially protrude into the interior space beyond an inner surface of the housing. 4. The blower of claim 1, wherein at least one rib at least partly spans the inlet, the rib being configured to support the filter. 5. The blower of claim 1, further comprising a humidity sensor or a moisture sensor, the sensor positioned at or near the inlet. 6. The blower of claim 1, wherein the backplate of the motor assembly is connected with the housing via a snap fit, and the backplate forms a part of an exterior of the blower. 7. The blower of claim 6, wherein the housing further comprises an aperture configured to at least partly receive the backplate. 8. The blower of claim 1, wherein the backplate is coupled to the circuit board. 9. The blower of claim 8, wherein at least a portion of the backplate is open to the surrounding environment. 10. The blower of claim 9, wherein, during operation, the circuit board produces heat, at least a portion of the heat being dissipated to the surrounding environment via the backplate. 11. The blower of claim 1, further comprising a vane positioned in the portion, the vane configured to direct at least a portion of the fluid, thereby promoting a substantially uniform fluid velocity across the length of the outlet. 12. The blower of claim 11, wherein the vane comprises a plurality of pins.
