ROOTS™ RCS 827 Rotary Positive Displacement Blower
Model: RCS 827
The ROOTS™ RCS 827 rotary positive displacement blower is built for demanding industrial airflow systems that require dependable high-volume performance and flexible installation capability. Delivering airflow up to 4650 CFM, this heavy-duty unit combines integral shaft ductile-iron impellers with precision alloy-steel timing gears for smooth and efficient operation. Its rigid grey iron casing, advanced oil-free compression design, and center-timed rotation system support long service life in continuous industrial applications.
Technical Details
The ROOTS™ RCS rotary blower series utilizes carburized and precision-ground timing gears securely mounted to heavy-duty shafts for reliable synchronization under load.
Cylindrical roller bearings on the drive end, combined with balanced gear-end ball bearings, help maintain stable operation.
Splash oil lubrication protects internal components during extended industrial runtime.
