EGV-132A-140 Oil-Free Permanent Magnet VFD Screw Blower
Core Advantages
1.100% Oil-Free Air Output for Premium Purity
0ppm residual oil with zero contact between rotor and lubricant. It eliminates contamination risks for food, pharma and electronics production.
2. PM VFD Direct Drive, 20%-35% Energy Saving
132kW permanent magnet motor with loss-free direct drive. Auto speed adjustment matches actual air demand. Class F insulation & IP55 protection enable stable work in harsh environments.
3. Low Heat & Less Wear, Ultra-Low Maintenance
Air cooling keeps host temp under 105°C and exhaust only 5~8°C above ambient to avoid overheat stops. Non-contact rotors reduce wear, annual maintenance cost drops below 40% of Roots blowers.
4. PLC Intelligent Control with IoT Compatibility
Built-in PLC + HMI touchscreen for real-time monitoring and fault alerts. Reserved IoT interface supports remote operation and data tracking.
5. Compact Low-Noise Structure, Easy Installation
Smooth airflow with weak pressure pulsation for quieter operation.
