ZW series air compressor adopts the method of pure water lubricate, the water pass the standard of drinking water. All compressing course is without lube oil. So it gives the compressed air 100% clean without lube oil.

¡ó Adopts excellent electric control system, and humanization maintaining index.

Each unit adopts microcomputer control system, with self checking and protecting function. The LCD panel will show the operating condition. When malfunction happens, the computer control system can responds to different condition. The computer control system can remind the customer to change fittings in time to maintain the equipment, the unit computer system has output port standby. The input connection port can realize multi set unit catenation control and far end control. To ensure its 24 hours working.

¡ó International technique main machine

The screw main machine adopts Japanese Mitsui Co., Ltd single screw water lubricate machine body. On 1982, It was developed in the market, since more than 20 years test, it gives high quality compressed air, saves energy, and highly reliable. All these prove its advanced technique quality. It has perfect structure, reach the total symmetry balance compressing. Little libration and less noise.

¡ó The high quality compressor without lube oil

Replace lube oil with water, realize four function, lubricating, cooling, sealing and anti-noisy. It gives 100% high quality compressed air without lube oil. No pollution, cleaning used water without special treatment, and match the environment protection demand. With the action of water, the compressing is a kind of perfect constant temperature compressing, each unit hose power wind quantity is 15% higher than the normal drying compressor.

¡ó Perfect constant temperature compressing

On the theory, when the 20 ¡æ air is compressed to 0.7Mpa in a adiabatic course, in the reason of no adding of any cooling medium compressing, the temperature of the air exhausted out is £¾250 ¡æ. We inject the lubricating water that for cooling into the compressing room, the temperature of the air exhausted out will be dropped down to 40¡æ, to obtain the high efficiency constant temperature compressing. The water content of the compressed air will be dropped down with the temperature down. At the same time, the lubricating water will bring the dust away from the air.

¡ó The standard demand

The air compressor and other fittings adopt suitable material and special treatment to avoid rustiness, the compressing room shim also the material, such as china, carbon fibre, etc. The high precision water filter will filtrate the impurity effectively, to ensure the lubricating water clean quality.
