Why Choose Airpol mEnergySmart Compressors?

 

Lower Energy Bills

The combination of variable speed drive (VSD) technology and an IE5-class permanent magnet (PM) motor can reduce energy consumption by up to 30% compared to conventional fixed-speed compressors. The compressor delivers exactly the amount of compressed air required by the system, eliminating unnecessary energy losses.

Maximum Energy Efficiency

Permanent magnet motors achieve efficiency levels of 94–96% and comply with the requirements of the IE5 energy efficiency class, ensuring outstanding performance across a wide operating range.

Lower Operating Costs

The direct-drive system, with no belt transmission, eliminates mechanical losses and reduces the number of components requiring regular replacement. This translates into lower maintenance costs and increased reliability of the entire compressed air system.

Quiet Operation

With a noise level of only 62 dB(A), the compressor can be installed closer to workstations, improving workplace comfort and reducing noise exposure.

 

VSD Technology – Intelligent Capacity Control

How Does a Variable-Speed Compressor Work?

The frequency inverter used in Airpol mEnergySmart compressors continuously adjusts the motor speed within a range of 25% to 100%. This enables the compressor to automatically match compressed air production to the actual demand of the installation, eliminating unnecessary energy losses.

Benefits of VSD Technology in AIRPOL mEnergySmart Compressors:

  • Up to 30% energy savings compared to fixed-speed compressors
  • Stable system pressure
  • Reduced idle running time
  • Lower load on the electrical network
  • Fewer motor starts and stops
  • Extended component service life
  • Measurable energy cost savings

 

Ultra Speed Function – Even Greater Flexibility

The unique Ultra Speed function allows smooth adjustment of the operating pressure within a range of 6.5 to 10 bar, increasing compressor output at lower pressure settings. In practice, users can obtain up to 35% more compressed air without increasing motor power.

This feature is particularly beneficial for applications with fluctuating compressed air demand.

Permanent Magnet (PM) Motor – Maximum Energy Savings

Airpol mEnergySmart compressors are equipped with advanced permanent magnet (PM) motors, which do not require rotor excitation current. As a result, energy losses typically associated with conventional induction motors are eliminated.

Key Advantages of PM Motors

  • 94–96% energy efficiency
  • IE5 energy efficiency class
  • IP65 protection rating
  • Oil-cooled design using compressor oil
  • Reduced maintenance requirements
  • Quiet and stable operation

 

 

Airpol-Manufactured Modular Screw Airend

 

At the heart of every compressor is the ASU modular screw airend, designed and manufactured by Airpol. The airend has been optimized for high performance, long service life, and simplified maintenance.

The integrated oil separator and oil filter minimize pressure losses and improve the overall energy efficiency of the compressed air system.
