Precision Scroll Design – Compact, Quiet & 100% Oil-Free
Baldor oil-free scroll compressors use a fixed and orbiting scroll plate system to compress air smoothly, silently, and cleanly.
Compression Principle:
Air is drawn into crescent-shaped pockets formed between the orbiting and stationary scrolls. These chambers gradually shrink as the scroll orbits, compressing the air toward the center discharge port.
- Contact-free compression chamber
- No lubrication required
- Stable, continuous airflow with minimal pulsation
Structural Advantages:
- Frictionless Compression – Longer Service Life No metal-to-metal contact reduces wear and increases reliability.
- Low Vibration, Ultra-Quiet Operation Scroll motion is continuous and balanced, enabling quiet performance as low as 52 dB(A).
- Fully Sealed Compression Chamber Oil and air channels are completely isolated to ensure contamination-free output.
- Minimal Maintenance, No Oil Changes No oil circuit means no oil refills, oil separators, or associated maintenance—saving time and cost.
