Industrial centrifugal fan

Konrad Reitz Ventilatoren GmbH & Co. KG KXE 250-050030-00

The Reitz KXE 250-050030-00 is an industrial centrifugal fan designed to generate a high total pressure increase in process installations. The assembly consists of a volute fan casing, an impeller mounted on a separately supported shaft, a coupled electric motor, and a common steel base frame with vibration-isolating mounts. The KXE design is suitable for moving air and process gases in systems requiring high flow rates and pressure. This unit was manufactured in 2020 for a rated volume flow of 500 m³/min and a total pressure increase of 2500 daPa. At its operating point, it delivers 602.4 m³/min at 1862 daPa and 3033 rpm. The shaft is supported by two 6318 bearings lubricated with Shell Gadus S2 V100 2 grease.
