DIRECT series

Directly driven compressors with endurance

  • Direct drive
  • Without power losses
  • High-performance in every kW class
  • Extremely efficient
DIRECT series logo

The brand new design of the DIRECT series of screw compressors enables ALMiG to set new standards in the world of compressed air systems with direct drive.
In this instance, direct drive means that the motor's output is transferred directly to the compressor stage without any loss by means of a v-belt or gear drive.
This type of drive is around 99.9 % efficient, i.e. much more efficient than standard drives: Even more compressed air from even less electric energy - around the clock.

The unique design concept of the DIRECT series makes it incredibly cost-effective in every kW class and therefore highly versatile. When these compressors with direct drive are combined with the VARIABLE series, they make an unbeatable energy-saving duo. Both compressed air systems have an identical design but the screw compressors of the VARIABLE product range also have a frequency converter.

Benefits of the energy-saving duo:

  • same system design
  • same components
  • same supply of spare parts
  • same handling
  • outstanding cost-effectiveness

The DIRECT series is available with volume flows of between 6.72 – 48.30 m³/min:

  • DIRECT 37 – 45
  • DIRECT 75 - 160
  • DIRECT 280 - 315

The compressors with direct drive can also be linked with the VARIABLE series to produce an unbeatable energy-saving duo.
