Roots RCS-J Whispair
RCS three-lobe frame with Whispair jet-porting.
Overview
The RCS-J pairs the highest-pressure Roots frame with Whispair porting. The result is a machine that hits 22 PSIG continuous while still meeting stringent pulsation and noise specs — the choice for dense-phase conveying inside sound-sensitive plants.
Key features
- Whispair on three-lobe geometry — lowest pulsation in the class
- 22 PSIG continuous pressure
- Preferred for dense-phase pneumatic conveying
