The so-called excellent efficiency of the fan means that the heat generated by the fan itself is reduced and the temperature is lowered. The exhaust pressure of various models in the dry state can reach ./㎡. Product features: The spiral shape is a fixed spiral type above D. The air inlet and exhaust shielding wires of the casing are cut into the spiral, and the triangular air inlet and exhaust openings formed by the smooth lines on the top of the rotor are gradually opened by the rotation of the rotor. The air inlet and outlet of this fan are not like the rotors of the old Roots blower, which cause the rotors to collide with each other due to slight axial displacement. Therefore, it is only necessary to ensure the rotor clearance on the cross-section. There is no need to add axial positioning like the old Roots blower rotor, so that the clearance becomes larger. The efficiency of this type of fan is better than that of spiral fans of the same size.
Each rotor has passed the dynamic and static balance test, and the unbalance factors have been eliminated and the operation is stable. Because the rotor adopts a special shape, it is easy to maintain the mutual gap between the rotors, further improving the efficiency. The output air is clean and does not contain any oily dust. There is no need for oil lubrication in the casing, and a structural design is adopted to prevent bearing and gear oil from mixing into the interior of the casing. Using advanced synchronous drive gears, the service life is extended and the noise is reduced.
