Two interleaved spiral scrolls — one fixed, one orbiting — compress air with minimal vibration.
Typical range
2–30 HP, up to 145 PSI
Best for
Clean air applications, medical, dental, lab, quiet environments.
Components
- Fixed scroll
- Orbiting scroll
- Tip seals
- Anti-rotation coupling
- Cooling fan
Common issues
- Loss of capacity → worn tip seals (typical life 10,000 hrs)
- Overheating → blocked fins, failed fan
- Noise / grinding → bearing failure on orbit drive
Maintenance
- 10,000 hrs: tip seal replacement
- Annual: clean cooling fins, inspect coupling
