Abstract

Air-moving devices, such as blowers and fans, have air filters as assembly components. These air filters are necessary to provide clean air, devoid of dust and debris, to the air-moving devices which blow cooling air over electrical and electronic components within the equipment enclosure or housing. In use, dust accumulates on the air filters, inhibiting the air supply to machine components. Failure to replace dirty filters can cause electronic components to heat excessively and may result in total failure of expensive machine parts.
