The bock vehicle compressor:The reliable core of every bus air conditioning system

Compact, light, powerful and reliable.

This is how in the 60s, the success story of Bock‘s FK series vehicle compressors began. It is a story which has not been outdone when it comes to innovation and technology at the highest level of quality available.

Whether in bus or railway air conditioning systems, transportation cooling, or in other mobile cooling applications, Bock FK compressors are the worldwide specialists.

We offer you a unique range of compressors in four basic models in two, four and six cylinder designs with a total of 16 displace-ment levels and depending on the application range, different design variants. In addition, we have numerous ways of adapting the compressor to your individual requirements.On the following pages you will find all the information on the latest stage of development FK50 size.

Come and talk to us, our competent team will be pleased to advise you.

Limits of application R134a

Notes

Limits of application

Compressor operation is possible within the examples in the diagram showing the limitations of use. The meaning of the surfaces marked in colour are to be observed. Limiting areas should not be selected for layout or continuous operating points.

Performance data

Performance specifications for the R134a are based on 20°C suction gas temperatures without liquid subcooling. Compressor speed 1450 rpm. The values can be stated to judge the overall performance at other speed with the help of the calculation factors below.

Preliminary data – Subject to change without notice.

Speed range:

N Design 500 - 3000 rpm (max speed 3500 rpm)

K Design 500 - 3500 rpm

Maximum permissible operating pressure (HP): 28 bar
