OEM Oil Free Water Lubricated Screw Air Compressor 37kW Supplier, Factories
Product Description
Core Advantages
100% Oil-Free Compressed Air, Zero Oil Contamination
No mineral oil is used for compression lubrication; purified water serves as the only lubricant. Outlet air reaches Class 0 oil-free grade (ISO 8573-1), no oil vapor, oil mist or oil residues in airflow, protects downstream equipment & finished products from oil pollution.
Water Lubrication Cooling, Higher Energy Efficiency
Water has far superior heat dissipation performance than lubricating oil. Compression temperature is controlled steadily at low level, reducing compression power consumption. Stable volumetric efficiency ensures consistent air output under long-hour continuous running, saves electricity bills greatly.
Ultra-Low Operation Noise & Smooth Running
Precision water-lubricated rotor pair with perfect meshing design, vibration minimized drastically. Built-in integrated silencing structure, overall noise ≤72dB(A), can be placed directly in production workshop without independent soundproof room.
Simple Structure & Low Maintenance Expense
Cancel complex oil separation, oil filtering, oil circulation systems required by oil-injected compressors. Consumables are only water filter, air filter, which are cheap and easy to replace; no regular oil change, oil separator replacement needed, annual after-sales cost cut by more than 60%.
Corrosion Resistant & Durable Internal Components
Main rotor, compression cavity are made of anti-rust stainless steel material, adapted to water lubrication working condition, no rust, long service life of host. Intelligent PLC control system supports automatic running, fault alarm, remote monitoring.
Environmentally Friendly & Safe
No waste engine oil discharge, green and pollution-free; water circulation closed-loop design, low water consumption, meets strict environmental protection inspection requirements worldwide.

Frequently Asked Questions
Q1 What is the difference between water lubricated oil-free compressor and traditional oil-free dry screw compressor?
A: Dry type oil-free compressor adopts two-stage compression without any lubricant, high temperature & high energy consumption, expensive spare parts. Our water-lubricated one uses single-stage compression with water cooling, lower power consumption, cheaper maintenance, more cost-effective for long-term use, and same Class 0 oil-free air quality.
Q2 Is the circulating water easy to handle? Will it cause internal rust?
A: We equip matched demineralized water treatment device. Adopt purified deionized water for circulation, the host cavity is all stainless steel, no rust occurs. Closed water loop consumes only a small amount of water every day.
Q3 Can this machine run 24 hours continuously all year round?
A: Yes. The whole machine is designed for industrial heavy-duty continuous operation. Stable temperature control system avoids overheating, widely applied in factories with non-stop production lines.
Q4 Can working pressure and air flow be customized?
A: Sure. We can adjust air displacement and rated pressure according to your on-site gas consumption demand, support 0.6~1.3Mpa pressure customization.
Q5 What are the regular consumables and replacement cycle?
A: Consumables: air filter, water filter. Replacement cycle: 2000~3000 hours. No compressor oil, oil separator need to be replaced, greatly reducing daily operating cost.
Q6 What after-sales service do you provide for overseas clients?
A: 2 years warranty for main host, 1 year warranty for electrical components. We supply lifelong spare parts supply, provide online remote troubleshooting guidance, and arrange overseas engineer on-site service if needed.
