How Do Oil-Free Scroll Air Compressors Work and What Are Their Advantages?

  • July 16, 2025

Today, clean air and efficient operation matter more than ever. V&T proudly introduces our advanced Oil-Free Scroll Air Compressor. This innovative machine is made for places where air quality is critical. It's the perfect power source for labs, healthc



What is an Oil-Free Scroll Air Compressor?


This compressor is a big step forward in air technology. Unlike old piston compressors, it doesn't need oil for lubrication. It uses a special scroll movement to squeeze the air. This guarantees the air coming out is completely oil-free. You get cleaner air, less maintenance, and no risk of oil contamination. It gives you peace of mind.


How It Works: The Smart Heart of the Machine


The orbiting scroll rotates in the order shown in Figure 1-2-3-4. The crescent-shaped compression chamber gradually decreases in volume, compressing the gas inside. The compressed gas is then discharged from the center of the fixed scroll.


Two precise spiral scrolls work together:

  1. Fixed Scroll: This part stays still. It forms the main compression chamber.

  2. Moving Scroll: A motor drives this part. It orbits in a tight circle around the fixed scroll.

Air gets pulled in. It gets trapped between these two scrolls. The moving scroll squeezes the air pockets smaller and smaller. Pressure builds steadily. Finally, clean, compressed air pushes out through the center. The scrolls never touch metal-to-metal. So, it needs no oil at all. This stops oil from ever getting into your air.


Why Choose Our Oil-Free Scroll Compressor?


  • Perfectly Clean Air:

    • Meets the strict ISO 8573-1 Class 0 standard for oil-free air. This means absolutely no oil, mist, or vapor in your air supply.

    • Gives you zero-risk air for critical jobs: precision labs, sterile drug making, safe food production, and high-end electronics.

  • Super Quiet Operation:

    • The unique scroll design doesn't need parts to touch, so it runs much quieter.

    • It works smoothly and quietly. Fits right into noise-sensitive places like labs, hospital rooms, cleanrooms, or offices. Makes the workspace better.

  • Great Energy Savings:

    • Squeezes air in one smooth, continuous motion. This wastes less energy.

    • Uses less power than old piston compressors. Saves you significant money on electricity bills over time. Good for your budget and the planet.

  • Compact Size, Saves Space:

    • Built in a smart, modular way. It's small and simple.

    • Fits easily under lab benches, in tight equipment corners, or other small spots. Makes the best use of your valuable space.

  • Built to Last, Easy to Care For:

    • The oil-free design means fewer parts can break. It runs reliably for a long time.

    • Maintenance is very simple. Mainly, just change the air filter regularly. Saves you time and money on upkeep.
