NOBEL Variable Speed Series Air Compressors

The NOBEL PM variable speed rotary screw air compressor range, available from 18.5 kW to 90 kW, is a high-performance industrial air compressor engineered for maximum efficiency, low energy consumption, and continuous-duty operation.

Featuring an advanced IE5 permanent magnet electric motor, zero-loss direct drive transmission, and integrated variable speed control, the NOBEL PM compressor automatically adjusts output to match demand. This intelligent design delivers up to 40% energy savings compared to conventional fixed-speed compressors while maintaining stable system pressure.

Key features and benefits include:

• Permanent Magnet Variable Speed Technology: Industrial rotary screw air end combined with a high-efficiency permanent magnet motor for superior part-load and full-load efficiency.
• IE5 High-Efficiency Electric Motor: Ultra-premium efficiency motor delivers maximum energy savings, reduced heat generation, and improved long-term reliability.
• Zero-Loss Direct Drive Transmission: Eliminates belt and gearbox losses, reducing maintenance requirements and improving overall compressor efficiency.
• Integrated Variable Speed Control: Automatically matches air output to system demand, reducing unloaded running and unnecessary energy use.
• Up to 40% Energy Savings: Significantly lower power consumption compared to traditional fixed-speed industrial air compressors.
• Constant Pressure Operation: Maintains stable air pressure, improving production efficiency and reducing energy waste.
• Simplified Maintenance Design: Easy and convenient service access minimises downtime and reduces ongoing operating costs.
• Flexible Installation Options: Available as floor-mounted or receiver-mounted units, with models supplied with or without an integral refrigerated air dryer.
• Star-Delta Starter: Reduces starting current and mechanical stress, extending motor and compressor service life.
• Extremely Quiet Operation: Low noise design allows installation closer to the point of use, improving workplace conditions.
• High Output with Reduced Energy Consumption: Optimised air end and drive system deliver high airflow efficiency across varying load conditions.
• Multiple Pressure Ratings: Available in 8 bar, 10 bar, and 13 bar versions to suit demanding industrial applications.
• Optional Remote Monitoring and Network Connectivity: Enables real-time performance monitoring, diagnostics, and integration into compressed air management systems.
