Abstract:
An air moving device assembly, comprising:a housing having an air inlet and an air outlet, said air moving device assembly having a first orientation wherein said air inlet is oriented in a first direction, and said air moving device assembly having a second orientation wherein said air inlet is oriented in a second direction substantially opposite said first direction; an air moving device within said housing for moving air from said air inlet to said air outlet; a back flow damper assembly positioned over said air outlet, said back flow damper assembly including: a first end baffle pivotally attached to a first end of said back flow damper assembly; a second end baffle pivotally attached to a second end of said back flow damper assembly, said second end being substantially opposite said first end; at least two middle baffles pivotally attached to said back flow damper assembly between said first and second end baffles; wherein, when said air moving device assembly is in said first orientation and in the event of a failure of said air moving device, said first end baffle and said two middle baffles cover said air outlet to prevent the back flow of air through said air outlet, and said second end baffle pivots away from said air outlet so as not to block the back flow of air though said air outlet; and when said air moving device assembly is in said second orientation and in the event of a failure of said air moving device, said second end baffle and said two middle baffles cover said air outlet to prevent the back flow of air through said air outlet, and said first end baffle pivots away from said air outlet so as not to block the back flow of air though said air outlet.
