Why Choose a KAESER 250 HP Rotary Screw Compressor?

Kaeser's 250-hp rotary screw air compressors provide outstanding efficiency and reliability. Featuring an energy-saving SIGMA PROFILE airend and a SIGMA CONTROL 2 controller, these compressors are designed to meet and exceed our customers' expectations, outperforming and outlasting other compressor solutions on the market.

Service-Friendly Compressor Design

Kaeser Compressors designs rotary screw compressors with the user in mind. Fewer wearing materials and using premium quality materials ensure reduced maintenance requirements, longer service intervals, and extended service life. Our DSD and ESD 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 screw compressor units. Lockable panels provide easy access to all maintenance items. Electrical components are housed in a spacious, ventilated control cabinet. Wiring is neatly arranged and terminals are clearly identified. When you consider the maintenance costs savings, it’s clear that owning a Built for a lifetime™ Kaeser compressor will save you money, year after year.

Guaranteed Efficiency

At KAESER our rotary screw compressors are designed with maximum efficiency in mind. Every component in a Kaeser rotary screw air compressor system is carefully designed with performance in mind. Unique components such as our patent-pending double-flow cooling fan increases air flow while reducing overall power requirements and the proprietary Sigma Profile airend is optimized for low airend speeds required from 250hp compressors. In fact, our DSD and ESD series 250 horsepower compressors are up to 30% more efficient than the competition guaranteeing lower operating costs regardless of your compressed air application.

Rugged Reliability

Kaeser’s screw compressors meet our rigorous “built for a lifetime” 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. Our 250 hp rotary screw compressors are equipped with high efficiency coolers ensuring reliable compressor operation in any environment. Filter mats simplify maintenance needs by capturing particle build up on the outside of the filter where it is easily seen and removed. This reduces the frequency of cooler servicing needs and ensures your compressor can operate in dust and dirt heavy environments. Due to their enclosure system, Kaeser’s totally enclosed, fan cooled (TEFC) motors used in our 250 HP air compressors are also less susceptible to dirt and dust than commonly used open drip proof (ODP) motors.
