Overview
The BMVF series permanent-magnet variable-frequency screw air compressor uses a permanent-magnet synchronous motor with VFD drive, automatically adjusting speed and air delivery to actual air demand and saving 20-35% energy compared with fixed-speed machines. Power coverage is 7.5-132 kW.
Key highlights
- ✓Permanent-magnet synchronous motor: high-efficiency permanent-magnet rotor, 5-8% more efficient than induction motors, with significant energy savings over long use.
- ✓VFD variable-frequency drive: precisely adjusts speed to actual air demand, steplessly regulating output to match demand.
- ✓20-35% energy saving compared with fixed-speed machines: variable-frequency control avoids frequent loading/unloading waste where demand fluctuates.
- ✓SKY patented screw air-end: Kaishan's core patented rotor profile for stable, reliable operation.
- ✓Soft-start characteristic: low variable-frequency starting current, little impact on the grid and no special power configuration required.
- ✓Low noise and low vibration: smooth variable-frequency operation without frequent start/stop shocks.
- ✓Intelligent control: HMI touchscreen display visualises parameters and supports remote monitoring.
- ✓Wide power range: 7.5-132 kW full series for different air-demand scales.
Applications: Processes with large air-demand fluctuations · Sandblasting · Pneumatic tools · Intermittent production · Automotive repair · Textile air-jet looms · Food processing · Pharmaceutical manufacturing · Energy-saving retrofits
