The LUFT 1000 INVERTER stands out with its direct-drive transmission, which offers significantly better efficiency and reduced power loss compared to belt-driven models. This innovative solution ensures optimal use of motor power, resulting in higher output and lower energy consumption. The maximum pressure generated by the compressor is 10 bar. Complete control over operating parameters is provided by the intuitive MAM-series electronic control panel, giving the operator access to all critical system data and ensuring maximum flexibility and process control.

Key Advantages of the 7.5 kW Induction Motor with Inverter Drive

Significant Energy Savings
The inverter enables smooth and precise regulation of the motor’s speed. The compressor adjusts its output to the current demand for compressed air, eliminating idle running, frequent start/stop cycles, and energy waste caused by venting excess air. Depending on your facility’s air usage profile, energy savings can range from 25% to even 50%. The more variable the air demand, the greater the potential savings.

Stable Air Pressure
With continuous speed regulation, the inverter maintains an almost perfectly stable pressure in the compressed air system, regardless of demand fluctuations. This is critical for the correct operation of pneumatic tools and machines, preventing pressure spikes and enhancing process accuracy.

Reduced Starting Current and Electrical Load
The inverter allows for soft-start motor operation, avoiding high inrush currents that can overload electrical networks and cause voltage drops. This protects the electrical infrastructure and reduces the risk of disturbances.

Extended Component Lifespan
Smooth operation without sudden starts or stops significantly reduces mechanical stress on the screw block, bearings, coupling, and motor. This translates into a longer service life for the compressor and lower maintenance and repair costs.

Quieter Operation
When operating at reduced speeds (during lower demand), the compressor generates less noise, improving the acoustic comfort in the workplace — a significant benefit for both operators and the surrounding environment.

Greater Flexibility and Demand Matching
The inverter-driven compressor can efficiently meet a wide range of compressed air requirements, making it an ideal solution for facilities with fluctuating air usage throughout the day, week, or month.

Advanced Control and Diagnostics
The inverter integrates with modern control panels to offer comprehensive monitoring, error diagnostics, remote control, and maintenance scheduling. This gives users full control and allows for optimization of the compressed air system’s performance.
