A Cabinet Filter Fan is a combination of a fan and a filtering system designed to be mounted on a cabinet or enclosure housing sensitive electronic equipment. Its primary function is twofold： to circulate air inside the cabinet to reduce temperature buildup, and to filter out dust, dirt, and other contaminants from entering the cabinet. The fan pulls in external air, cools it, and pushes it into the enclosure, where it helps regulate internal temperatures. Simultaneously, the filter captures particles and ensures only clean air enters the equipment, reducing the risk of malfunctions caused by debris.
