Not only do these compressors deliver more compressed air for sustainable energy savings, they also combine ease of use with exceptional reliability and simple maintenance.  \nInnovation you can trust  \nWith a cutting edge research and development team committed to building industry-leading products, KAESER continues to deliver better solutions to meet our customers’ compressed air needs. KAESER’s expertise and world-wide reputation for superior reliability and efficiency offer great performance and peace of mind.  \nRugged reliability  \nKAESER’s screw compressors meet our rigorous “built for alifetime” standard. Designed and built with KAESER’s generations of compressed air experience, you can rest assured that these compressors will continue to deliver the air you need with the exceptional reliability you expect from a KAESER COMPRESSOR.  \nService-friendly  \nFrom the ground up, these compressors have been designed with the user in mind. Fewer wearing parts and using premium quality materials ensure reduced maintenance requirements, longer service intervals, and extended service life. A smart component layout with generously sized maintenance doors simplifies service and reduces downtime.  \nGuaranteed efficiency  \nIn our systems design approach, KAESER chooses the components that work together in the most energy efficient way possible. Each and every component — from inlet filter to discharge connection — has been carefully designed with performance in mind. In fact, the S series are up to 30% more efficient than the competition. With KAESER’s superior system controls, we guarantee an effective system with lower operating costs.  \nPotential energy cost savings through heat recovery  \nCompressed air system investment  Maintenance costs  \n Energy costs  \n Potential energy cost savings  \nEnergy cost savings through system optimization  \nService-friendly design  \nThe SX, SM, and SK series rotary screw compressors feature an open package layout. All of the major components are easily accessible, reducing preventive maintenance time by as much as 50% when compared to other similarly sized units.  \nWhen you consider the energy efficiency savings and the maintenance costs savings, it’s clear that owning a Built for a lifetime™ KAESER COMPRESSOR will save you money, year after year.  \nSide panel windows to view fluid level and test the auto drain (on T versions and AIRCENTERS)  \nSingle piece, multi-ribbed belt.
