Fan, a fan system including a fan and a mounting assembly, and method of mounting a fan

A directional fan system comprising:

• a directional fan assembly including
• a cage housing including a front cage section, a rear cage section spaced from said front cage section along a central axis and including a mounting plate, and a cylindrical cage section disposed annularly about said central axis and extending between said front cage section and said rear cage section such that said front cage section, said rear cage section, and said cylindrical cage section cumulatively define a housing interior;
• a central hub supported for rotation about said central axis;
• and
• a plurality of airfoils coupled to and distributed circumferentially about said central hub for rotation about said central axis with said central hub;
• a motor assembly coupled to said mounting plate of said rear cage section of said cage housing and including a motor shaft coupled to said central hub such that said central hub and said plurality of airfoils rotate about said central axis in response to rotation of said motor shaft;
• and
• a mounting assembly configured to support said directional fan assembly relative to a mounting structure, said mounting assembly comprising:
• an upper mounting bracket assembly configured to be coupled to the mounting structure;
• an extension member having a top portion coupled to said upper mounting bracket assembly and a bottom portion;
• and
• a lower mounting bracket assembly including a yoke having a first yoke arm coupled to said mounting plate, a second yoke arm coupled to said mounting plate and spaced from said first yoke arm, and a central yoke portion coupled to and extending between said first yoke arm and said second yoke arm, with said central yoke portion coupled to said bottom portion of said extension member, wherein said yoke is pivotably coupled to one of said mounting plate and said bottom portion of said extension member such that said yoke is pivotable about a pivot axis to adjust an orientation of said directional fan assembly.

A method of mounting a directional fan assembly to a ceiling mounting structure, said method comprising:

• coupling a top plate of an upper mounting bracket assembly to the ceiling mounting structure, the upper mounting bracket assembly including a pair of adjustment brackets defining:
• coaxial bores defining an adjustment axis;
• and
• an adjustment slot radially spaced from the adjustment axis;
• coupling a top portion of an extension member to the pair of adjustment brackets by disposing a fastener through the coaxial bores and the top portion of the extension member such that the extension member is pivotable about the adjustment axis;
• coupling a bottom portion of the extension member to a directional fan assembly with a lower bracket assembly such that the directional fan assembly is supported by the extension member;
• adjusting the lower bracket assembly to support the directional fan assembly at an orientation relative to the extension member;
• permitting the extension member, the lower bracket assembly, and the directional fan assembly to pivot about the adjustment axis until the extension member, the lower bracket assembly, and the directional fan assembly reach a static equilibrium orientation relative to the upper mounting bracket assembly;
• and
• disposing a fastener through the adjustment slot and the top portion of the extension member to retain the extension member, the lower bracket assembly, and the directional fan assembly at the static equilibrium orientation.
