Portable compressors – MOBILAIR

Construction site compressors - Made in Germany: powerful and efficient with long-term value retention

MOBILAIR portable compressors from KAESER always impress with their exceptional versatility and dependability. The range extends from 1 m³/min all the way up to an oil-free 45 m³/min. Whether mobile or stationary, powered by combustion engine or electric motor – these portable powerhouses can be specifically adapted for any application, thanks to a multitude of available equipment options. 

Portable compressors are well equipped for the demands of heavy-duty, continuous operation in construction site environments. They also perform reliably and safely, even under harsh climatic conditions. A durable polyethylene enclosure (availability dependent on model) makes MOBILAIR units especially rugged and ensures excellent value retention. Portable compressors are simple to operate and enable excellent accessibility to all maintenance-relevant components, which means all service work can be accomplished efficiently. 

Kaeser’s company slogan applies to every model in the MOBILAIR range: More compressed air for less energy. KAESER offers portable compressors optionally equipped with engines capable of running on diesel with a high sulphur content, as well as operation in extreme ambient temperatures, high humidity levels and installation altitudes up to 3000 m above sea level. For the European and North American markets, the portable screw compressors are equipped with drive motors that comply with the EU Stage V emission standard.
