Quiet, ultra-efficient fourth-generation spiral compressors generating completely pristine, 100% oil-free air for contamination-sensitive indoor setups.

Frank Oil-less Scroll Air Compressors represent a highly efficient breakthrough in compression technology, recognized globally as the fourth generation of industrial compressors. Utilizing a stationary involute scroll combined with an eccentrically moving scroll disk, this layout creates compressed air volumes with maximum volumetric efficiency and zero internal oil lubrication. Perfectly optimized for indoor industrial and medical deployment, these robust assemblies seamlessly support hospitals, clean laboratories, breweries, and high-tech electronics plants nationwide.
Features a rugged cast iron construction equipped with integrated single-point water jackets and dedicated intercoolers. Designed specifically for uninterrupted, long-term industrial production with minimal upkeep cost.
The non-contact orbital compression mechanism reduces friction, producing minimal noise velocity and vibration. This ensures ideal operator safety, low workplace noise pollution, and optimized power containment.
