VEHICLE COMPRESSOR SERIES FK40/755 - EXPANSION FOR HOTTER CLIMATES

15 % MORE POWER AT THE SAME SIZE

BOCK open type vehicle compressors FK40 for mobile applications

With the most powerful version FK40/755, BOCK offers its customers 15 % more power with the same external dimensions. BOCK vehicle compressors are equipped with the K valve plate system as standard. They are ideally suited for bus air conditioning with increased cooling power requirements in city-, intercity and articulated buses or in areas with very warm ambient temperatures.

Compact lightweight
  • Optimised heat dissipation due to ribbed surface
  • Efficient over the entire speed range

 

Robust and powerful
  • Robust crankshaft design with roller bearings on both sides: works extremely reliably and with high speed stability
  • Split screwed aluminium connecting rods: stable and robust, thus easy to handle

  • Reliable pressure lubrication with powerful oil pump independent of direction of rotation

  • Extremely low wear, thus extremely durable

  • 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
Low-temperature valve plate
Low temperature valve plate vehicle compressor

Valve plate TK version for low evaporating temperatures

  • Special version for low-temperature cooling
  • Based on the basic N valve plate concept
  • With additional measures to optimize the degree of delivery at low evaporating temperatures
  • Piston heads provided with grooves in the suction lamella contour: for further minimization of damage space and increased performance in the low-temperature range

vehicle compressor range and performance includes

3 sizes and 11 displacements
