Oil-Free Air Compressors vs. Oil-Injected Air Compressors

  • ISO-certified technology.

  • No lubricant required for operation, highest air quality.

  • Low maintenance with no oil changes or filters to replace.

  • Ideal for applications requiring pure, oil-free air, such as medical and dental settings.

  • High energy efficiency with reduced operating costs.

  • Higher upfront cost but lower operating costs over time.

Oil-Free vs. Oil-Injected Compressors

  • Lubricated with oil and suitable for industrial applications such as construction and textiles.

  • May require regular maintenance but offer longevity and consistent performance.

  • May be suitable for industrial settings where air purity requirements are less stringent.

  • Lower upfront cost but potentially higher maintenance and operating costs.
