and better bhp/ton performance.
Patented flow-optimized suction inlet improves
volumetric efficiency and reduces noise.
Service-friendly design combines long-life
sleeve bearings with easy access thrust
bearings that can be replaced without removing
the compressor.
Double-acting hydraulic capacity control,
infinitely adjustable from 10% to 100%.
