ABSTRACT:
The disclosure provides a system having a cage mounted in an air-moving system, such as a wet and dry vacuum cleaner, which provides energy-absorbing structural ribbing for a more robust cage. The energy-absorbing ribs can tolerate impacts better than the relatively stiff, axial ribs aligned in a longitudinal direction of the cage found in prior efforts. The energy-absorbing ribs are formed in a non-aligned direction to the longitudinal axis, that is, at some non-zero angle to the axis. Circumferential ribs can be formed at some angle to the energy-absorbing ribs.
