In contrast with Root's blower, Oil-free Air Blowers can save 35% energy at most
The Energy Efficiency Contrast Diagram between Screw Air Blower and Traditional Root's Air Blower.
The pressure/ volume diagram of screw blast blower 
Energy consumption / Energy saving ◆ Thermodynamic energy consumption ◆ Energy saving 4→1: Suction 1→2: Internal compression. Intermeshing of opposing rotors, decrease of volume between teeth, and increase of pressure. 2→3: Exhausting. The air is discharged from the pipe. | The pressure/ volume diagram of Root's blast blower 
Energy consumption ◆ Thermodynamic energy consumption 4→1: Suction 1→2: The air volume remains unchanged. Air is compressed outside due to the backpressure of pipe network. 2→3: Exhausting. The air is discharged from the pipe. |
Performance Advantages of Screw Air Blower Contrasted with Root's Air Blower:
1. Higher efficiency, lower noise;
2. Allowing a higher rotating speed and tooth-crest speed;
3. Capable of reaching a higher discharge pressure;
4. A lower pressure fluctuation;
5. Root's blast blower does not have internal compression.
