Key Features & Design

• Advanced Rotors: Features high-strength ductile iron bi-lobe impellers that are machined as a single piece and dynamically balanced for vibration-free operation.
• Dual Splash Lubrication: Provides oil lubrication at both the gear and drive ends, which is critical for long-term reliability in severe duty applications.
• Helical Timing Gears: Precision-machined from alloy steel forgings and mounted on shaft splines to ensure quiet operation and non-slip timing.
• Leak-Free Design: Utilizes advanced piston rings and flinger seals to maximize seal life and prevent oil contamination of the air stream.
