| Structure |
Simple and Balance Structure |
Radial load is not balance |
| Vibration and Noise |
Low vibration and noise |
High frequency noise due to the two screws |
| Durability |
Ideal Rotation speed 3000r/min, theoretically zero load.
Long lifetime of the screw (30000h) and star wheel (50000h)
|
Rotation speed 18000r/min, high loads on screws.
Short lifetime of screw (8000~18000h)
|
| Maintenance |
Only air and water filter elements |
