SM Series

SM Series Rotary Screw Compressors (7.5 to 15 HP)

Industrial-grade efficiency, quiet operation, and advanced system automation for medium shop air requirements.

The Kaeser SM Series provides dependable compressed air for facilities requiring 19.3 to 55.8 cfm at working pressures up to 217 psig. Built around Kaeser's energy-saving SIGMA PROFILE® airend and featuring a single-belt drive with automatic belt tensioning, the SM Series bridges the gap between small workshops and full-scale industrial production..

Why Choose the Kaeser SM Series?

Advanced Automation & Intelligent Control

  • SIGMA CONTROL Automation: The SIGMA CONTROL continuously tracks operating metrics, predicts maintenance needs, and integrates with factory management systems or the SIGMA AIR MANAGER 4.0 master controller.
    Standard Anybus Interface: It connects to your PLC or SCADA network via interchangeable communication modules.
    Supported Protocols: Modbus TCP, PROFIBUS DP, PROFINET IO, EtherNet/IP, BACnet/IP, and OPC UA.
  • Energy-Saving SIGMA PROFILE® Airend: Delivers maximum air volume per kilowatt, driving specific power consumption down by up to 30% over standard designs.
  • TEFC Motor & Magnetic Wye-Delta Starter: Premium-efficiency totally enclosed fan-cooled motors with Class F insulation come standard with reduced-voltage starters to prevent high electrical current surges.

Low-Maintenance Power Transmission

  • Automatic Belt Tensioning Device: Unlike manual adjustment systems, SM Series units feature a unique tensioning mechanism that maintains correct drive belt alignment and tension. This maximizes energy transmission, extends component life, and lets technicians verify belt status through a cabinet inspection window. 
  • 3-Stage Separation System: Centrifugal separation combined with dual coalescing filters keeps oil carryover under 2 ppm, ensuring clean discharge air and reducing fluid top-off needs.

Space-Saving Quiet Enclosure

  • Acoustically Insulated Cabinet: Heavy-gauge steel housing with thick sound-dampening insulation keeps sound emissions between 65 dB(A) and 68 dB(A), allowing direct placement near active work areas.

  • Dual-Zone Cooling System: Draws intake air through separate paths for the drive motor and heat exchangers, preventing internal heat buildup and extending lubricant life.

  • Single-Panel Service Access: Generous maintenance doors give technicians quick access to spin-on fluid filters, air intake cartridges, and external cooler mats.

Typical Applications & Operating Environments for the SM Series

  • Collision Repair & Paint Spray Booths: With the integrated dryer ("T" model) option, it supplies continuous, moisture-free, pulse-free air to spray guns, eliminating fish-eyes, blistering, and surface rework on vehicle finishes. 
  • Small-to-Medium CNC Machine Shops: Handles constant demand for pneumatic chucks, automated tool changers, and continuous chip blow-off across single- or two-shift production schedules. 
  • Commercial Bakeries & Craft Breweries: Supplies reliable motive power for bottling, canning, and packaging equipment while the SIGMA CONTROL 3 automates pressure tracking and service schedules.

Browse rotary screw compressors by rated horsepower (HP)

horsepower icon

Our 3-30 hp compressors use a space-savings v-belt drive design and many are available as complete compressed air systems with receiver tanks and integrated dryers. On larger units we use only true direct drive, providing maximum power transfer and efficiency from motor to airend. Options include integrated refrigerated dryers and variable speed drive.

Frequently Asked Questions

What horsepower ratings are offered in the Kaeser SM Series?

The SM Series includes 7.5 HP, 10 HP, and 15 HP compressor configurations.

What is the advantage of the automatic belt tensioner in the SM Series?

The SM Series automatic belt tensioner maintains correct belt tension continuously. This prevents power loss caused by belt slippage, eliminates frequent manual tension checks, and prolongs drive component life.

Does the SM Series include smart controller capabilities?

Yes. Every SM compressor includes the SIGMA CONTROL™ internal controller. It provides pre-programmed operating modes, operational logging, maintenance tracking, and standard Ethernet connectivity for remote system management.
