The CFJ dust fan features a single-plate backward-blade impeller design, with welded side plates and scroll plates to ensure good structural rigidity. This fan delivers high efficiency, low noise, and a smooth performance curve. It maintains a consistent flow rate even as static pressure continuously rises, ensuring adequate incoming air suction. The fan is equipped with a B35 motor, and the discharge outlet angle is adjustable. It is specifically designed for dust collection in dust collectors and laser cutting machines. Additionally, this fan can be used for ventilation in industrial and mining enterprises, as well as in large buildings such as basements where high resistance is present.
