ABSTRACT:
A self-cleaning filter and cooling system are disclosed for filtering ambient air used to cool the interior of an equipment enclosure. The system includes an enclosure for housing predetermined equipment to be cooled, the enclosure including an air intake port and an exhaust port. The system includes a blower for causing ambient air to be inducted into the enclosure through the air intake port and expelled from the exhaust port. The system also includes a filter that includes a predetermined filter media that covers the air intake port and the exhaust port. The filter moves relative to the air intake port and the exhaust port. The enclosure and blower are configured so as to create a single air flow path for equipment cooling and for discharging exhaust through the filter media to dislodge any particulate matter entrapped in the filter media.
