110kw Two Stage Pm Inverter Type Electric Drive Air Compressor 8bar Screw Air Compressor
Introduction
Our Permanent Magnet Variable Frequency Integrated Screw Air Compressor delivers maximum efficiency, quiet operation, and long-term cost savings for industrial and commercial applications. Engineered with advanced two-stage compression technology, this 110kW unit provides stable 8bar pressure output while significantly reducing energy waste.
Core Advantages
- 30–40% Energy Savings – The combination of two-stage compression and a high-efficiency Permanent Magnet (PM) motor, paired with an integrated Variable Frequency Drive (VFD), automatically adjusts motor speed to match real-time air demand. This eliminates wasteful unloading cycles and significantly reduces power consumption compared to traditional fixed-speed or single-stage units.
- Stable & Reliable 8bar Output – Two-stage compression ensures consistent airflow with minimal pressure fluctuations (as low as ±0.01 MPa), making it ideal for sensitive applications where pressure stability is critical.
- Maintenance-Free PM Motor – No brushes, no slip rings, no rotor windings. This design reduces wear, extends service intervals, and ensures long-term operational reliability with minimal upkeep.
- Ultra-Quiet Operation – Optimized screw rotor profiles combined with a heavy-duty soundproof enclosure keep noise levels as low as 65 dB, making this compressor suitable for indoor and noise-sensitive work environments.
- Smart Control System – The user-friendly LCD touchscreen provides real-time monitoring, performance analytics, fault alerts, and remote control capability, enabling predictive maintenance and seamless Industry 4.0 integration.
- Compact & Space-Saving Design – Fully integrated with a built-in cooling system, this unit reduces installation footprint and simplifies piping and wiring requirements.
- High-Quality Components – Premium bearings, corrosion-resistant rotors, and efficient air-oil separation/filtration systems ensure long service life and minimized downtime.

FAQ
Q1: How does two-stage compression save more energy than a single-stage unit?
A: Two-stage compression cools the air between the first and second stages, reducing the overall work required and minimizing internal leakage. When combined with the PM motor and VFD, the system runs at peak efficiency across all load conditions—delivering 30–40% energy savings.
Q2: What is the maximum working pressure of this model?
A: This 110kW model is rated for a stable 8bar discharge pressure, making it ideal for most general industrial applications. (Other pressure variants may be available upon request.)
Q3: How loud is this compressor during operation?
A: Thanks to the optimized screw rotor design and advanced soundproof enclosure, noise levels are kept as low as 65 dB, which is comparable to normal conversation level and suitable for indoor installation.
Q4: Is the Permanent Magnet motor truly maintenance-free?
A: Yes. The PM motor has no brushes, slip rings, or rotor windings that require periodic replacement. This eliminates a major maintenance cost and significantly extends service life.
Q5: How difficult is the installation process?
A: Very easy. The unit comes in a pre-assembled, plug-and-play design with an integrated cooling system. Simply connect the power supply, attach your air pipelines, and start operation—minimal site preparation required.
Q6: What is covered under warranty?
A: We offer a 1-Year Motor Warranty along with comprehensive coverage on core components, ensuring you have full peace of mind with your investment.
