LENTO series screw compressor – oil-free compressed air of outstanding quality

Performance class: 15 – 110 kW

LENTO series

Environmentally-friendly compressor with maximum cost-effectiveness

  • Integrated Refrigeration dryer
  • Stepped operating pressure and volume flow
  • Minimised maintenance and service costs
  • Oil-free to ISO class 0
Oil-free logo

Screw compressors of the oil-free LENTO series deliver maximum cost-effectiveness in compressed air treatment by precisely matching the volume flow to the exact compressed air requirement and through low compressed air outlet temperatures and minimised service and maintenance costs.

Not only is there demand for high-quality, 100 % oil-free compressed air in the pharmaceutical, foodstuffs, electrical engineering and medical industries, but wherever products of the highest quality are produced. Therefore ALMiG's oil-free compressors of the LENTO series deliver maximum compressed air quality in highly sensitive areas of use.
Only water, the most natural of all raw materials, is used in the compression process. This produces:

  • Clean, environmentally-sound compressed air without oil; dust particles drawn in are washed out by the water
  • Clean condensate – pure water – can be discharged directly into the sewer system
  • Very low temperatures during compression thanks to excellent heat transfer via the water. Only tiny amounts of energy are therefore used to generate the compressed air

LENTO variants

The screw compressors of the LENTO series are available with stepped operating pressures of 5 – 13 bar and individually adaptable volume flows in various variants:

  • LENTO 15 – 30
  • LENTO 31 – 80
  • LENTO 81 - 110
Oilfree screw compressor LENTO - details

  1. Compressor

    • Single-stage, water-injected
    • The housing made from non-rusting alloy encloses the two efficient-compression rotors (main and secondary rotors)
    • Very low final compression temperatures of less than 60°C (i.e. close to isothermic, economical compression)

  2. SCD motor

    • Highly efficient drive motor
    • IP 55 ISO F protection class
    • Compact
    • High-performance
    • Reliable


  3. Integrated refrigeration dryer with three jobs to do

    • It produces fresh water for permanently generating and exchanging the coolant needed
    • It ensures optimum biological and chemical water quality
    • It delivers dry compressed air at the inlet

  4. Water circuit

    • Closed water circuit with self-contained, integrated water treatment
    • Multi-stage separation for dry compressed air


  5. Direct drive

    • Zero-loss power transfer
    • Huge cost savings


  6. SCD frequency converter

    • The integrated power pack; EMC guidelines met of course


  7. Air Control

    • The intelligence of the compressor. It thinks, monitors, documents

Potential for saving energy

The speed-controlled direct drive of the LENTO series delivers maximum cost-effectiveness through

  • Volume flow adapted exactly to meet compressed air requirements
  • No switching cycles or resultant expensive idle times
  • Energy-saving soft start without current peaks Operating pressure can be freely selected between 5 - 13 bar in 0.1 bar steps
  • The reduction in pressure achieved saves money

The integrated refrigeration dryer:

  • Ensures low compressed air outlet temperatures, i.e. the customer doesn't need a separate refrigeration dryer
  • Avoids the cost of fresh water and water treatment

The oil-free LENTO series minimises service and maintenance costs compared with other, oil-free compression systems.
