800 RCS Series Blowes
Frames 817 thru 827

RCS rotary blowers are heavy-duty units designed with integral-shaft ductile iron impellers having an involutes profile. The head plates, gear cover, end cover and rigid, one-piece casing are gray iron. Carburized and ground alloy steel spur timing gears are taper mounted on the shafts, secured with a locknut. Cylindrical roller bearings are used on the drive end with ball bearings on the gear end. Piston rings reduce air leakage through the shaft openings in the head plates, and lip-type oil seals prevent lubricant from entering the air chamber. The RCS incorporates thrust control, with splash oil lubrication at both ends of the blower.

• Carburized and ground alloy steel spur timing gears.
• Piston rings reduce air leakage while lip-type oil seals prevent lubricant from entering the air chamber
• Center-timed for rotatino in either direction
• Pressures 1 thru 18 psig (69 thru 1241 mbar)
• Vacuums to 16 and" Hg (542 mbar)
• Flows 935 to 5200 cfm (1589 to 8835 m3/hr)

RCS-J and RCS-VJ Rotary Blowers
Frame sizes 715J and 721J

RCS-J WHISPAIR™ rotary blowers are heavy-duty units designed with integral-shaft ductile iron impellers having an involutes profile. WHISPAIR blowers reduce noise and power loss by utilizing an exclusive wraparound plenum and proprietary WHISPAIR jet to control pressure equalization – feeding back flow in the direction of impeller movement, thereby aiding rotation. The head plates, gear cover, drive end cover and rigid, one-piece casing are gray iron. Carburized and ground alloy steel spur timing gears are taper mounted on the shafts, secured with a locknut. Cylindrical roller bearings are used. Piston rings reduce air leakage through the shaft openings in the head plates, and lip-type oil seal prevent lubricant from entering the air chamber. The RCS-J incorporates thrust control, with splash oil lubrication at both ends of the blower. Frame sizes 715J and 721J are designed with detachable rugged steel mounting feet that permit in-field adaptability to either vertical or horizontal installation requirements.

RCS-J Blowers
Incorporates ROOTS Whispair technology to reduce noise levels.

RCS-VJ Blowers
RCS Whispair units are available with an inlet spray nozzle and seal water flow meter for water injection.  This feature cools the vacuum unit to enable it to reach deeper vacuum.
