Roots RCS Rotary Blowers
Straight-lobe blowers for the highest pressures in the PD family.
Overview
The RCS series pushes single-stage rotary lobe pressure into territory usually reserved for two-stage machines — up to 22 PSIG continuous. Cast iron construction, three-lobe rotor geometry and integral silencing make it the right choice for pneumatic conveying of dense phase material.
Key features
- Three-lobe rotor design reduces pulsation and noise
- Integral inlet and discharge silencers standard
- Cast iron construction; horizontal or vertical airflow
- Available as J (jacketed) for cooling on gas service
