The BITEMAN Aquapure Oil-Free Screw Air Compressor features innovative water-molecule lubrication technology, using water as the lubricating medium in the compression chamber to eliminate oil-related components from the compression process. This design helps prevent oil contamination at the source and delivers high-quality, 100% Class 0 oil-free compressed air.
Unlike conventional oil-free compressor designs, Aquapure integrates efficient compression and water management technologies to simplify system configuration. It eliminates the need for a conventional aftercooler and water circulation or purification system, while continuously producing industrial-grade purified water during operation. The compressed air can be connected directly to a downstream BITEMAN desiccant air dryer to meet demanding air quality requirements.
