RCS Units

Roost RCS series are heavy-duty units with integral-shaft ductile iron impellers in an involute profile. The headplates, gear cover, drive end cover and rigid, one-piece casing are grey iron. Carburized and ground alloy steel spur timing gears are taper mounted on the shafts and secured with a locknut. Cylindrical roller bearings combined with high volume oil reserves offer low maintenance and trouble free operation. Piston rings reduce air leakage through the headplate shaft openings, while lip-type oil seals maintain lubricant in the roller bearings. All RCS series blowers are equipped with splash oil lubrication at both ends of the blower.
