Rotary Screw Compressors
KAESER's patented SIGMA PROFILE rotors set the global standard for compressed air efficiency. Available with fluid cooling (oil-injected) and oil-free compression variants, these compressors deliver exceptional performance across a wide range of pressures and flow rates. The SIGMA CONTROL 2 onboard controller ensures intelligent, reliable operation — 24/7, 365 days a year.
Reciprocating Compressors
KAESER reciprocating (piston) compressors cover an exceptionally wide range — from small workshop units to high-pressure industrial boosters. Available in portable and stationary configurations, complete ready-to-use packages, and OEM blocks. Engineered for reliability in demanding duty cycles where high pressure is required.
Portable Compressors — MOBILAIR
The KAESER MOBILAIR range delivers robust, road-ready compressed air wherever it is needed. Diesel and electric-powered models are built for construction sites, pipeline projects, mining, and remote operations. Weatherproof housings, efficient low-fuel-consumption engines, and tool-free service access make these the go-to choice for tough environments.
Screw Blowers
KAESER's rotary screw blower packages set the benchmark for low-pressure, high-volume air delivery. The oil-free screw element delivers significantly lower specific power consumption than traditional lobe blowers — saving up to 35% energy. The complete ready-to-connect packages include an integrated frequency drive, SIGMA CONTROL 2, aftercooler, and silencer for plug-and-play installation.
Lobe Blowers
KAESER rotary lobe blowers — also known as Roots-type blowers — provide dependable, oil-free air and gas transfer for a broad range of low-pressure applications. Available as bare blocks for OEM integration or as complete noise-insulated packages, KAESER lobe blowers are built to last with precision-machined rotors, robust bearings, and minimal maintenance requirements.
Refrigeration Type Dryers
KAESER refrigeration dryers remove moisture from compressed air by cooling it to near freezing, causing water vapour to condense and drain away. The result is clean, dry compressed air with a stable pressure dew point — protecting downstream equipment, preventing corrosion, and ensuring consistent process quality. Energy-saving cycling and non-cycling variants are available to match any duty profile.
Desiccant Dryers
KAESER desiccant dryers use adsorption technology to achieve extremely low pressure dew points down to −70 °C, making them indispensable wherever moisture could damage products or processes. Heatless, heat-reactivated, and blower-purge models cover every energy profile. KAESER's ECO Control ensures drying cycles are demand-driven, slashing energy waste.
ECO Drains
Condensate is an unavoidable by-product of compressed air generation. KAESER ECO Drains eliminate it without wasting a single litre of compressed air. Unlike timed solenoid drains that blow off valuable air, ECO Drains use capacitive level sensing to open only when condensate is actually present — delivering measurable energy savings and zero false trips on every installation.
Line Filters
KAESER compressed air filters deliver multi-stage contaminant removal — capturing oil aerosols, particulates, water droplets, and vapours before they reach sensitive equipment or processes. The low differential pressure design minimises energy losses while the visual indicator clearly signals filter element service intervals. Available in general-purpose, fine, and activated-carbon grades.
Air Receivers
KAESER air receivers act as a buffer between the compressor station and the distribution network — absorbing demand peaks, reducing compressor cycling, and stabilising system pressure across all shifts. Manufactured in accordance with applicable pressure vessel directives, each receiver is corrosion-protected and primed for long service life. Available in horizontal and vertical configurations from 90 to 10,000 litres.
Controller
KAESER controllers bring intelligent automation to your compressed air station. The SIGMA CONTROL 2 onboard controller manages individual compressors, while the SIGMA AIR MANAGER (SAM 4.0) coordinates entire compressed air networks — continuously optimising energy consumption, monitoring performance, and enabling remote diagnostics and reporting.
AIRpipe — Modular Aluminium Piping
AIRpipe is a globally trusted modular aluminium piping system engineered to deliver compressed air with zero leaks and minimal pressure drop. With over 25 years of innovation and more than 42,000 km of pipe installed across 32,000+ projects worldwide, AIRpipe has become the industry standard for clean, efficient air distribution. The system is 70% lighter than steel, fully corrosion-free, and assembles with precision push-fit fittings — requiring no welding, no threading, and no specialist tools. The smooth interior bore minimises friction and turbulence, reducing pressure loss and allowing compressors to run more efficiently. The lock-and-seal design ensures a leak-free system from compressor to point of use, while the modular architecture makes future expansion or layout changes fast and cost-effective. Compatible with all compressor brands and rated to 16 bar.
