ROOTS™ RCS 824 Rotary Positive Displacement Blower

Model: RCS 824

The ROOTS™ RCS Rotary Blower 824 provides incredible air-moving power up to 4460 CFM through a spacious 12-inch flange connection. Weighing 1330 pounds, this system employs integral shaft ductile-iron impellers with an involute profile inside a rigid grey-iron casing. Taper-mounted steel spur timing gears combine with piston-ring air seals to stop leakages, guaranteeing completely oil-free compression for massive manufacturing plants.
