Oil free lubrication air compressor is a type of compressed gas equipment that replaces traditional oil lubrication with water lubrication. It belongs to the completely oil-free air compressor type, and its core feature is that no lubricating oil is used in the compression stage and the output gas does not contain oil (oil content ≤ 0.01ppm). This equipment uses pure water that meets drinking water standards as the lubricating medium, and reduces component loads through water film lubrication technology and axial/radial force balance design. It has the characteristics of high compressed air quality (compliant with ISO 8573-1 Class 0 standard), low operating noise, and better cooling efficiency than oil lubrication systems. Compared to traditional oil lubricated compressors, it saves energy by 18% -36%, eliminates maintenance costs for accessories such as oil filters and oil gas separators, and provides pure compressed air that can extend the life of gas equipment. It is widely used in fields such as medicine, food, electronics, and laboratories that require high gas purity.
The oil-free lubricated air compressor achieves 100% oil-free compressed air output by replacing traditional lubricating oil with water as the sealing and cooling medium. Its core selling points include:
Purity guarantee: Water film isolation technology ensures that compressed air is free of oil and meets ISO 8573-1 Class 0/1 standards, suitable for fields such as food, medicine, electronics, etc. that require strict gas purity requirements;
Energy saving and efficient: The high specific heat capacity of water improves cooling efficiency, saving more than 15% energy compared to two-stage dry twin-screw. The exhaust temperature is stably controlled below 80 ℃, and long-term energy consumption is lower;
Environmentally friendly and low maintenance: No need for lubricating oil and related consumables (such as oil filters), annual maintenance cost is only 1/5 of traditional oil lubrication models, and there is no waste oil pollution;
Stable and durable: Water lubrication reduces mechanical friction, single screw design balances axial force, low noise and significantly reduces failure rate;
Widely applicable: covering medical, laboratory, food processing and other scenarios that require clean compressed air. Some models can be adapted to drying machines to further control humidity.
Oil free lubricated air compressors are widely used in fields with strict air quality requirements, such as the pharmaceutical industry (operating rooms, ICUs, dental equipment, laboratory analytical instruments, etc. requiring sterile environments), due to their 100% oil-free compression (oil content ≤ 0.01ppm) and ultra-high cleanliness that meets ISO 8573-1 Class 0 standards; Food processing (avoiding oil contamination in production and packaging processes); Electronic manufacturing (preventing oil adhesion in the production of chips and precision components); And in the fields of aerospace and military industry (ship accessories, precision instruments), automotive spraying (to avoid paint stains), chemical new energy (explosion prevention and pollution prevention), etc. In addition, in industrial scenarios such as environmentally friendly water treatment, textile and papermaking, printing, and marine machinery that require energy-saving and environmental protection solutions, its water lubrication technology can reduce maintenance costs by 40% and achieve zero oil pollution emissions.
