25 to 125 hp Kaeser Screw Compressors

Kaeser built the ASD, BSD, and CSD series for continuous-duty industrial environments where air demand is steady and downtime carries real cost. These Kaeser industrial screw compressors serve a broad spectrum of applications across manufacturing, processing, and fabrication. 

Metal fabrication and machining operations rely on consistent pressure for CNC machining centers, plasma cutting, laser cutting assist gas, and pneumatic clamping systems. Pressure drops in these environments translate directly to part tolerances and cycle time, making the CSD series' six pressure variants particularly useful for dialing in exact system requirements. 

Automotive production and assembly facilities use compressed air across paint booths, body assembly tooling, tire inflation stations, and robotic actuators. The BSD series' output range from 196 to 289 acfm covers most mid-size automotive assembly and finishing applications without oversizing the system. 

Food and beverage production lines use compressed air for pneumatic conveying, filling equipment, labeling, and packaging. In these environments, consistent compressed air quality is as important as volume, and the T-model integrated refrigerated dryers ensure air meets quality standards at the point of use. 

Plastics and rubber processing equipment, including injection molding machines and blow molding systems, operate with air-actuated platens, robotics, and ejection systems. The Kaeser CSD series' airend delivers the higher flow rates these processes require in a compact footprint. 

Woodworking and furniture manufacturing shops running routers, sanders, nailers, and finishing equipment typically find the ASD series' 25 to 40 hp output well matched to their volume needs, especially with the SFC variable-speed option, which helps track fluctuating demand through shift changes. 

General manufacturing and assembly operations, from electronics assembly to consumer goods production, benefit from the ASD, BSD, and CSD series' ability to integrate directly into plant-wide control architectures via the SIGMA AIR MANAGER 4.0, bringing all compressor assets under coordinated management.

The 25- to 125-hp capacity in Kaeser's direct-drive lineup comprises three series, with each industrial screw compressor matched to a distinct flow and installation profile. 

ASD series (25–40 hp): The ASD is the right starting point for operations with moderate compressed air requirements. Flow rates from 111 to 192 acfm at 125 psi cover most single-shift manufacturing cells, smaller assembly lines, and job shops. The compact footprint makes installation practical in facilities with constrained machine room space. 

BSD series (40–60 hp): The BSD bridges the gap between lighter manufacturing loads and heavier continuous-production demands. With output from 196 to 289 acfm at 125 psi, it fits multi-press fabrication shops, production finishing lines, and operations running two tools or process lines simultaneously. The integrated refrigerated dryer in the T-model configuration is located in a separate cabinet — not exposed to preheated air or compressor contaminants — for operations where point-of-use treatment is part of the compressed air system design. 

CSD series (60–125 hp): The CSD is Kaeser's direct-drive workhorse for high-demand industrial environments. Six discrete pressure variants from 100 to 217 psig let you match the machine's output precisely to your system's pressure requirement, rather than throttling a higher-pressure machine. Flow rates up to 702 acfm at lower pressures make the CSD 175 one of the highest-output options in this power class. 

For operations with variable demand cycles, the SFC variable-speed models across all three industrial screw compressor series use IE5 motors and meet IES2 system efficiency class, the highest rating available under IEC 61800-9. Pairing an SFC compressor with a base-load fixed-speed unit gives multi-shift facilities flexibility and efficiency across the full demand curve.
