Designed for efficient, eco-friendly compressed air supply, this water-lubricated medium-pressure screw compressor combines advanced screw technology with water-based lubrication to deliver clean, oil-free airflow (critical for sensitive applications). Operating at medium pressures (typically compatible with 8-13 bar(e) ranges), it balances robust performance with low maintenance: the water-lubrication system reduces friction, lowers operating temperatures, and eliminates oil contamination risks—making it ideal for industries like food processing, pharmaceuticals, or electronics manufacturing.
