3 - 30 HP Rotary
V-Belt Drive

Kaeser's rotary screw compressors with V-Belt design are the most economical and reliable in the industry. Thanks to its highly effective belt-tensioning system, any drawbacks to a belt system have been eliminated.

15 - 335 HP Rotary
Variable Speed Drive

Not every air compressor system can benefit from a variable speed drive. For those plant requirements where such a system would be desirable it's important to get the right equipment to meet the needs.

20 - 30 HP Rotary
with Dryer

In the Kaeser AS T Series of compressors air is drawn into separate cooling zones for the drive motor and coolers. This "split cooling" design eliminates pre-heating, increasing cooling efficiency.

25 - 100 HP Rotary
with Dryer

The Kaeser ASD, BSD and CSD Series of compressors offer a rugged and reliable integrated compressor/dryer package that defies common misconceptions about "package" design.

25 - 300 HP Rotary
Direct Drive

The one-to-one direct drive units provided by Kaeser are true "direct-drive" air compressors. In Kaeser direct drive packages, one-to-one drive reduces the number of components needed, thus increasing reliability and service life.

335 - 605 HP Rotary
V-Belt Drive

The Kaeser FS/GS/HS Series of rotary screw V-Belt drive air compressors range from 335 horsepower to 605 horsepower with capacities from 1,200 to 3,308 cfm and pressures from 50 to 205 psig.
