CORMAK LUFT 700 VSD+PM COMPACT Screw Compressor with Dryer – Compact Set for Demanding Applications - ENERGY SAVER

Looking for a professional air supply solution for workshops, paint shops, or small production lines? The CORMAK LUFT 700 VSD+PM COMPACT screw compressor with integrated dryer is the perfect choice. With a 5.5kW motor and an actual capacity of up to 690L/min, it provides a consistent air supply for impact wrenches, blow guns, paint sprayers, or sandblasting equipment.

This model is designed for continuous operation, making it ideal for demanding applications such as tyre services, large car workshops, or production facilities. Investing in a CORMAK screw compressor means improved working comfort – say goodbye to noisy piston compressors and enjoy quieter, more stable operation.

The screw compressor is equipped with a built-in refrigeration dryer ensuring dry and clean air, which protects your system from corrosion and damage.

The LUFT 700 VSD+PM COMPACT oil-injected compressor with dryer features a traditional belt drive, providing easy maintenance and lower service costs. Belt replacement is simpler and cheaper than direct-drive repair, and with no rigid coupling between the motor and working elements, mechanical wear and stress are reduced, resulting in longer component life.

The compressor delivers a maximum pressure of 10 bar. Complete control of operating parameters is provided by the intuitive MAM electronic control panel, giving access to essential machine data and enabling precise process control.

✅ Pressure: up to 10 bar | ✅ Air capacity: up to 690L/min | ✅ Power: 5.5kW

Energy Saver Line: A New Era of Efficiency

The Energy Saver line represents advanced screw compressors designed to drastically reduce operating costs. In an environment where energy represents nearly 80% of compressed air system costs, these models have become the industrial standard.

Key features that distinguish these models:

1. Permanent Magnet Motor Technology (PM)

Most compressors in the Energy Saver series use Permanent Magnet motors. Compared with standard induction motors:

They achieve efficiency levels meeting IE4 or even IE5 standards.
They maintain high efficiency even at low speeds (standard motors lose efficiency outside their nominal range).
They are smaller, lighter, and generate less heat.

2. Advanced Frequency Inverter Control (VSD)

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

Demand-based operation: The compressor does not work in an “all or nothing” load/unload cycle. If your application requires only 30% capacity, the inverter reduces motor speed, consuming proportionally less energy.
Elimination of idle running: Traditional compressors often run unloaded for several minutes after tank filling, consuming about 25–30% of nominal power. Energy Saver models virtually eliminate this wasted process.

3. Soft Start

Thanks to inverter technology, the compressor starts smoothly from 0Hz. This means no current surges at startup, which:

Protects the plant’s electrical installation.
Allows frequent start/stop cycles without overheating the motor windings.

4. Real Energy Savings

In practice, the Energy Saver line reduces electricity bills by 30% to 50% compared to fixed-speed compressors. The system maintains stable network pressure (with an accuracy of 0.1 bar), crucial for precision tools like laser cutters. Longer service life: Fewer pressure and temperature fluctuations extend the screw block lifespan.

Main Advantages of Permanent Magnet Motors (PM)

Permanent Magnet (PM) motors represent an innovative approach to electric drives, offering numerous advantages over traditional induction motors.

Higher energy efficiency: PM motors generate their own magnetic field using permanent magnets, eliminating rotor current losses and Joule heating. This leads to greater efficiency, often exceeding IE4 Super Premium class, especially at low speeds.
Improved power factor: PM motors draw less current for the same useful power, reducing reactive energy losses and network load.
Compact design and higher power density: PM motors deliver more power in smaller, lighter housings—ideal for space-limited or weight-sensitive applications.
Constant torque and high dynamics: They maintain constant torque even at low speeds, offering rapid dynamic response and precise speed control—ideal for CNC machines or robotics.
Wide speed range: Field-weakening strategies allow PM motors to operate efficiently across a wide range of speeds.
Increased reliability and longevity: Reduced heating, simple rotor design, and lower mechanical stress ensure long-term reliability and durability.

Inverter / VSD – Key to Compressor Optimisation

The inverter (frequency converter) revolutionises screw compressor operation by allowing smooth adjustment of motor speed according to air demand.

Key advantages of inverter-driven compressors:

Significant energy savings: The inverter matches air production to consumption, eliminating idle running and start/stop losses, saving 20–50% energy depending on usage profile.
Stable system pressure: Smooth motor speed regulation maintains nearly constant network pressure, essential for consistent pneumatic tool performance.
Reduced start-up current: The inverter provides soft starting, preventing current surges and extending motor and component lifespan.
Extended component life: Fewer start-stop cycles and optimal load operation reduce mechanical wear and service costs.
Quiet operation: Lower motor speed during reduced air demand directly decreases noise levels.
Adaptability: Ideal for applications with variable air demand typical in modern production plants.
Advanced control and diagnostics: Integrated monitoring, remote control, and maintenance planning ensure full system management.
