Design
World-Class Efficiency
Our new state-of-the-art modular airend design features an optimised rotor profile that delivers significantly improved efficiency and best-inclass airflow. The premium e-variants with their watercooled airend jackets enable even greater energy savings.
Robust Components
Proven, trouble-free airends with patented UltraCoat™ technology, oversized bearings, a rugged motor design, coolers enabling operation at ambient temperatures up to 46°C and hydraulically actuated inlet valves provide reliability for life.
Flexible Design Options
Our compressors offer air-cooled and water-cooled configurations, fixed and regulated speed, different pressure variants, extreme ambient temperature options, high dust filtration and outdoor modifications for harsh environments and many more to best match your application.
Simple and Serviceable
Our oil-free compressor package design is simple and spacious – no special tools are required to perform maintenance, and all components are easily accessible. Our durable consumables and wearables lengthen service intervals.
Higher Rated Cooling
Capacity Our compressor systems are designed for operation at ambient conditions up to 46°C. This provides an additional cooling margin for trouble-free operation at higher temperatures, and again contributes to the overall reliability and efficiency of the compressor package.
The Air end – How we build reliability into every detail What makes our oil free DX screw compressors range unique?
Compressor rotors take a beating. Over time, their surfaces can deteriorate, leading to reduced air flow and increasing risk of corrosion. CompAir eliminates this problem with UltraCoat, an advanced rotor and housing protection process that ensures the most durable coating, with unmatched adhesion properties and temperature resistance. In conjunction with a second-stage stainless steel rotor, UltraCoat delivers greater reliability in performance and air quality, rotor longevity, increased uptime, and reduced energy costs.
Perfect motor - drive - airend design
D-RS Series features a high efficient Power Drive System
that exceeds the class IES2 EN61800-9 requirements and
assures high energy savings across broad flow range.
Wide regulation range
No cycles means substantial energy savings
