Performance Specifications:
| Power Rating | Free Air Delivery | Working Pressure | Noise Level |
|---|---|---|---|
| 45kW | 7.2-8.1 m³/min | 7-13 bar | 68±2 dB(A) |
| 55kW | 9.5-10.8 m³/min | 7-13 bar | 70±2 dB(A) |
| 75kW | 12.8-14.5 m³/min | 7-13 bar | 72±2 dB(A) |
The innovative frequency conversion technology maintains optimal pressure within ±0.1 bar fluctuation, eliminating the energy waste common in fixed-speed compressors during partial-load operation. Modular design allows for straightforward maintenance with accessible service points, while the corrosion-resistant cabinet housing provides IP54 protection against industrial contaminants.
Operational benefits include:
- 35-40% average energy reduction compared to fixed-speed models
- Soft-start feature reduces electrical surge impact on power grids
- Automatic sleep mode during low-demand periods
- Remote monitoring capability via industrial communication protocols
- Extended service intervals up to 8,000 operating hours
Backed by our decade-long manufacturing expertise and global logistics network through Qingdao, Shanghai, and Tianjin ports, we ensure reliable product support across 15+ international markets. Our compressors undergo rigorous quality verification at each production stage, delivering operational continuity for automotive manufacturing, textile production, and food processing applications.
