All standard RCS blowers are center timed to allow rotation in either direction. RCS series blowers incorporate detachable steel mounting feet to permit adaptability to either vertical or horizontal installation.

Frame Sizes 817 thru 827

RCS-J WHISPAIR™ PD Blowers
RCS-J WHISPAIR Series Positive Displacement Blowers

RCS WHISPAIR™ blowers reduce noise and power loss by utilizing a wrap-around plenum and proprietary WHISPAIR™ jet ports to control pressure equalization. The WHISPAIR™ jets meter discharge pressure in the direction of impeller movement, thereby aiding rotation. Discharge pulsation is reduced by the pre-pressurization of the blower chamber. This reduced pulsation results in lower noise, and reduced shock loading on the system components.

Frame Sizes 715J thru 832J

RCS-VJ WHISPAIR™ PD Blower
RCS-VJ WHISPAIR Positive Displacement Blowers RCS-VJ WHISPAIR™ water-sealed vacuum exhausters are heavy-duty blowers designed with integral-shaft ductile iron impellers.
