Oil Free Rotary low pressure screw compressors

ZE&ZA : high-performance low pressure oil-free air compressors. ZE/ZA fixed and variable speed drive low-pressure oil-fee air compressors: high quality performers with a robust design.

ZE Truck unloading application Customer testimonial

Schomburg has facilitated the transport of their bulk materials through the installation of an efficient stationary compressor system. Two oil-injected GA screw compressors and two oil-free ZE low pressure compressors were installed. The installation improved the quality of the raw materials and dramatically increased the efficiency of the pneumatic transport. Schomburg has been around for 80 years. The core competences of the company are: building sealing, repair and tile composite sealing. Two of our ZE 2 oil-free compressors now supply the unloading points with conveying air. With the purchase of these compressed air solutions, Schomburg not only solved the noise problem, but also improved the compressed air quality and the conveying process itself.
