Huakang Zhongtian single machine dust collector is a small and efficient dust removal and purification equipment. Suitable for various dust production points, flexible and convenient, on-site dust collection and treatment can ensure the cleanliness of the air. The basic structure consists of a dust removal box, a centrifugal fan, a filter bag (filter cartridge), and a control cabinet. Dust is sucked into the dust removal box through a vacuum suction pipe by the negative pressure of the fan. Using gravity and upward airflow, the coarse particle dust is first filtered by the filter and directly dropped to the dust collector. The fine particle dust is captured on the outer surface by the filter. The clean gas is filtered, decomposed, and purified by the filter element before flowing into the clean room, and then discharged from the air outlet by the fan.
