The R series (legacy SCHIELE brand)

The R series is a range of single-stage centrifugal turbo blowers with a closed-type overhung impeller in a fabricated, modular design, allowing optimum adaption to nearly all process requirements. This machine range derives from the legacy SCHIELE brand and is available in direct drive, as well as integral or separate gear configuration.

The R series serves demanding duties in process gas or air service applications, even in harsh environments. It provides state-of-the-art safety and reliability at lowest lifecycle costs to their owners. Gas flows up to 350,000 m³/h can be handled.

This machine range is optionally available in a design compliant to API Standard 673, 617 or 672.
