Centrifugal fans build pressure by accelerating air outward through a rotating impeller, making them the workhorse for HVAC air handlers, cleanrooms, dust collection and process ventilation. Articles under this tag cover working principles, backward vs forward curved impellers, performance-curve reading, selection math and maintenance practice, with LONGWELL AC/DC/EC centrifugal fan data for reference.
