(1) A fixed spiral method with a spiral shape of 20 ° or more. The intake and exhaust shielding wires of the casing are cut into the spiral and sequentially opened by the rotation of the rotor. So the operating sound is extremely low, with almost no exhaust pulsation.

(2) Because the rotor is a three bladed linear shape, it will not come into contact with each other due to slight axial displacement. Only ensuring the clearance between rotors on the profile is sufficient, without the need for axial displacement of the rotor, which would result in excessive clearance.

(3) The rotor adopts a special shape, which facilitates maintaining the mutual clearance between rotors and further improves efficiency.

(4) Due to the use of precision CNC machine tools for mass production of rotors, there is no performance error between each fan. In addition, the rotor has reached a balanced state during the manufacturing process, and the vibration of this machine is minimal.

(5) By using the highest level drive gear, the measurement accuracy reaches level 5, which not only extends the lifespan but also achieves low noise. The bearings are made of NSK Seiko products from Japan, which have lower noise levels.

(6) The output air is clean and free of any oily dust. There is no need for oil lubrication inside the casing, and a structural design is adopted to prevent bearing and gear oil from mixing into the interior of the casing.

(7) With the establishment of the company wide quality management and production workshop management system, the goal of mutual communication between components, low production costs, and short-term delivery has been achieved.

(8) Adopting a compact design with a small installation area.
