Open 2-, 4- and 6-cylinder compressors in all-aluminium lightweight construction

  • Light and compact design
  • Demand-oriented capacity regulation possible
  • Unique valve plate option
  • Wide speed range
  • Robust and easy to service
Compact lightweight
  • Compact design and low weight
  • Optimised heat dissipation due to ribbed surface
  • Efficient over the entire speed range

 

Robust and powerful
  • Special crankshaft design with

    bearing on both sides: works extremely reliable and speed resistant

  • Split connecting rods operate with low circumferential speeds and are easy to replace

  • Pressure lubrication with powerful oil pump

  • Oil pump which is independent of the direction of rotation

  • Extremely low wear, thus extremely
    long service life

  • Valve plate systems specially adapted to the field of application

valve plate K FK 40
Valve plate: K-design

Unique FK valve plate system specially developed for bus air-conditioning

  • Valve plate made of aluminium
  • Working valves made of high-quality, impact-resistant spring steel
  • Extremely robust and reliable in the face of speed and pressure fluctuations as well as exposure to liquids
  • Long service life due to loosely guided annular discs which prevent bending and torsional forces
  • Highest operational safety and efficiency

 

Valve Plate N FK compressor
Valve plate: N-design

Cost-effective and simple alternative to the K version

  • For universal use in mobile applications
  • Lamellas clamped on one side, which are exposed to bending and torsional forces; therefore limited load-bearing capacity at  high speed and exposure to liquids

vehicle compressor range and performance includes

3 sizes and 11 displacements
