3. Advantages for oil-free water lubrication screw air compressor:


1). No oil, cleaner
The whole air compressor does not need to add any lubricating oil inside to make the outlet gas cleaner.
2). Stainless steel, safer
The parts in contact with compressed air in the system are made of 304 or 316 stainless steel to prevent pollution in the compression process and ensure the safety of gas.
3). low speed, high efficiency, more environmental protection
The main engine and motor are connected by elastic coupling, and there is no gearbox and other variable speed device, which makes the main engine and motor rotate at the same speed, reducing noise and vibration less.
The compression temperature of the host machine is about 50ºC, close to isothermal compression, effectively reducing energy consumption.
Using water as a lubricant, the entire life cycle of the equipment does not produce any waste oil discharge.

4).Simple structure and low maintenance cost

The machine structure is simple, easy to maintain, only need to replace the air rate and water filter element, no lubricating oil, greatly reduce the maintenance cost.
