CORMAK LUFT 1000 VSD+PM COMPACT +270l tank

CORMAK LUFT 1000 VSD+PM Compact Screw Compressor with Dryer – Compact Set for Demanding Applications – ENERGY SAVER

INCLUDES:

- LUFT 1000 VSD+PM COMPACT SCREW COMPRESSOR with integrated dryer
- 270 L horizontal compressed air receiver tank

Key features that distinguish these models:

1. Permanent Magnet Motor (PM) Technology

Most compressors in the Energy Saver series utilize Permanent Magnet motors. Unlike standard induction motors:

- They offer efficiency levels in line with IE4 or even IE5 standards.
- Maintain high efficiency even at very low rpm (standard motors lose efficiency outside their nominal range).
- Are smaller, lighter, and generate less heat.

2. Advanced Frequency Inverter Control (VSD)

At the heart of the Energy Saver line is a frequency inverter (VSD).

- Demand-based adjustment: The compressor does not operate in an all-or-nothing (load/unload) system. If your machinery requires only 30% output, the compressor reduces its speed and proportionally lowers energy consumption.
- Elimination of idle running: Classic compressors often run for several minutes after filling the air tank, consuming about 25–30% of nominal power without producing compressed air. Energy Saver models almost completely eliminate this wasteful process.

3. Soft Start

Thanks to the frequency inverter, these units start smoothly from 0 Hz. This means there are no sudden current spikes during startup, which:

- Protects your facility’s electrical installation
- Allows for more frequent machine starts and stops without the risk of motor winding overheating

4. Genuine Savings

In practice, Energy Saver models enable a reduction in electricity bills by 30% to 50% compared to traditional fixed-speed compressors. Additionally, the system maintains very stable network pressure (accurate to 0.1 bar), which is critical for precision equipment such as laser cutters. Extended lifespan: The absence of rapid pressure and temperature fluctuations lengthens the working life of the screw stage.
