BSD – Setting the standard

KAESER KOMPRESSOREN pushes the boundaries of compressed air efficiency once again with its latest
generation of BSD series rotary screw compressors. Not only do they deliver more compressed air for less
power consumption, but they also combine ease of use and maintenance with exceptional versatility and
environmentally responsible design.

BSD – Multiple savings Perfect partners

The new BSD compressors save energy in multiple BSD series rotary screw compressors are perfect
