A-O series piston compressor – oil-free compressors with individual modular system and direct drive

Performance class: 1.5 – 3.8 kW

Compact compressed air stations for all operating conditions

  • Oil-free compressed air
  • Direct drive
  • Highly efficient intake filter
  • Smart modular system

Supremely tough yet economical describes the air-cooled single or two-stage and also the oil-free compressors of the A-O series with direct drive. In terms of quality, operating reliability and service life, they set the standard for industrial facilities and guarantee maximum overall reliability and cost-effectiveness.

Technical features:

  • Cylinders of high-quality grey cast iron with deep fins
  • Cast aluminium cylinder heads
  • High-performance cast-iron axial fan
  • Needle bearings in both push rod eyes
  • Brand-name pressure switch with operating hours counter as standard (for version on receiver)
  • Large, highly effective intake filter Energy-saving motor (Eff 1) – IP 54 protection, protection class F

The compact design, performance increments and smart modular system allow piston compressors to be used cost-effectively around the clock. They can be individually and reliably adapted to all operating conditions. The compressed air systems are therefore even ideal for sensitive areas of application such as medicine/hospitals, foodstuffs.

The modular system comprises:

  • Compressor units for installation purposes
  • Units on base frame for free installation
  • Compressed air systems with horizontal or vertical receivers (also with coupled refrigeration dryers)
  • Compressed air systems with or without sound insulation box
  • Compressed air systems as A-tower, freely configurable with up to 3 units of the same type

The variants of the A-O series:


Thanks to the modular system, the A-O series is available in various combinations and can be individually adapted to numerous operating conditions. The compressors are available with volume flows of 170 – 620 l/min at a max. final pressure of 10 or 15 bar.
