Air Compressor

We carries a full range of rotary screw air compressors, with Kaeser’s energy-saving design features delivering significantly more air per kW. Our air compressor are designed to work together to achieve maximum efficiency, reliability and optimum performance.

Rotary screw air compressors with belt drive up to 22 kW (30 hp)

Technical Specification

Series: SX – ASK
Motor power: 2.2 to 22 kW
Delivery: 0.26 to 3.5 m³/min
Standard pressure: 8/11/15 bar(g)

Design Features

Automatic belt tensioning
The automatic belt tensioning device ensures consistent transmission efficiency and excellent drive-system reliability. (Not required for SX series)
Optimised separation system
The combination of optimum flow separation and the special separator cartridge results in a minimal fluid content of less than 2 mg/m³ in the discharged compressed air. The separator system also requires very little maintenance. (SX series models feature an external separator cartridge)
Cooling air filter mats
Ambient air used for cooling is contaminated to some degree, but the filter mats through which the air is drawn into the cabinet prevent the cooler from clogging.

Rotary screw air compressors with direct drive up to 90 kW (120 hp)

Technical Specification

Series: ASD to CSDX
Motor power: 18.5 to 90 kW
Delivery: 2.63 to 16.16 m³/min
Standard pressure: 5.5 to 15 bar(g)

Design Features

Energy-saving 1:1 drive
The motor and airend are joined by the coupling and its housing to form a compact and durable unit that is virtually maintenance-free. Furthermore, reliability and service life are increased through elimination of wear and transmission losses, as 1:1 drive reduces the number of components needed in comparison with gear drive.
Low speed operation
Large, low speed airends are more efficient than small high speed airends because they supply more air for the same drive power. Low speeds mean less wear and consequently less maintenance costs.
Radial fan: Quiet and efficient
The quiet and powerful radial fan draws in cool ambient air through the cooler. Its high residual thrust allows the use of exhaust ducting without the need for an additional extractor fan. In addition, the radial fan consumes significantly less drive power than conventional axial fans, saving even more energy.

Rotary screw air compressors with direct drive up to 500 kW (667hp)

Technical Specification

Series: DSD to HSD
Motor power: 75 to 500 kW
Delivery: 13.62 to 83.4 m³/min
Standard pressure: 5.5 to 15 bar(g)

Other Design Features

SIGMA Control 2
The control unit features an easy to read display and durable input keys. All relevant information can be viewed at a glance and user-friendliness is further enhanced by the logical menu structure coupled with the ability to display data in any one of 30 selectable languages.

Service-friendly savings
Excellent accessibility to all maintenance and service relevant components
minimises maintenance effort and therefore costs.

SIGMA Profile Airend
At the heart of every compressor system lies a premium quality airend featuring KAESER‘s SIGMA PROFILE rotors. Operating at low speed, Kaeser‘s airends are equipped with flow-optimised rotors for superior efficiency.

Maximum Efficiency IE3 Motors
Kaeser rotary screw airends are powered by IE3 drive motors for maximum performance and reliability.

Save energy with the KAESER SIGMA PROFILE
Every KAESER rotary screw airend is equipped with energy-saving SIGMA PROFILE rotors. Components manufactured to the highest standards and precision aligned roller-bearings ensure long service life with maximum reliability.
