1. A mounting device for mounting a fan unit, the mounting device comprising:
a reference plane and a reference axis normal to the reference plane, the fan unit being receivable towards the reference plane along the reference axis when the fan unit is in a disengaged orientation;
a set of engagement members radially disposed around the reference axis and arranged to surround the fan unit when the fan unit is in the disengaged orientation at the reference plane, the engagement members engageable with the fan unit upon rotation of the fan unit, the rotation being along a first rotational direction about the reference axis from the disengaged orientation to an engaged orientation; and
a set of engagement elements disposed on the engagement members, the engagement elements engageable within a set of mounting holes of the fan unit when the fan unit is at the reference plane and upon rotation of the fan unit to the engaged orientation,
wherein upon engagement with the fan unit when the fan unit is in the engaged orientation, the engaged engagement members resist movement of the fan unit along the reference axis and the engaged engagement elements resist rotation of the fan unit about the reference axis;
wherein when the fan unit is in the disengaged orientation, the engagement members are configured to prevent rotation of the fan unit from the disengaged orientation to the engaged orientation and thereby prevent engagement of the fan unit, the rotation being along a second rotational direction opposing the first rotational direction, and
wherein each of the engagement members comprises a weakening or stiffening element for increasing or decreasing, respectively, a stiffness of the engagement member or wherein each of the engagement members comprises an extension mechanism for adjusting an engagement distance of the engagement members.
