7KW Silent Oil Free Screw Compressor Water Lubricated 100% No Pollution Variable Speed

Silent Screw Type Compressor Water Lubricated 100% Oil Free With No Pollution

Water-lubricated oil-free air compressors are widely used in aerospace, chemical, textile, electronics, medicine, food, bottle blowing, laboratory and other high-end industries and fields with special process requirements. The main structure of water-lubricated oil-free screw air compressors adopts The single screw is all stainless steel, the lubricating medium adopts pure water that meets drinking water standards, and is equipped with high-performance stainless steel components. There is no lubricating oil in the entire compression system, and it is becoming more and more popular in the market!

Compared with oil-filled air compressors, water-lubricated oil-free screw air compressors realize low-temperature compression, low-speed operation, simple structure, and convenient maintenance, so maintenance costs are greatly reduced. However, due to congenital defects such as the need for lubricating oil for smooth operation, oil-filled air compressors lead to complex structural design and cumbersome maintenance, so the operating cost is much higher than that of water-lubricated oil-free air compressors. Obviously, the advantages of water-lubricated oil-free air compressors are extremely obvious.

Key Product Features:
 

1.Pure air, pure gas, zero pollution - what you need is what we want to do.

2.Exhaust temperature is only 40-50℃ Isothermal compression method increases the volume efficiency by 15% compared with other oil- free screw air compressors.

3.Only need to change the air filter and water filter, the maintenance cost is low and the use is economical and convenient.

4.The main screw airend and air pipes are made of 304 and 316 stainless steel corrosion-resistant materials. Even after several years of normal use. they are still new and lasting.

5.Pressure range is 0.3-1.6 MPA. And single stage compression can be easily completed.

Common oil-free air compressor applications

1.Tobacco,Petroleum and chemical industry,Non-ferrous metals
Increase safety, prolong normal working time, reduce failure frequency and maintenance cost, reduce equipment downtime and maintenance time.

2.Pharmaceutical, medical
Compressed air is used at every step from mixing, hardening and granulation to drying, pressing, coating and packaging, and compressed air comes into contact with pharmaceuticals at nearly every step of the manufacturing process

3.Food
In automated filling, packaging and bottling lines, compressed air is used to control various valves and actuators. Oil-free compressed air prevents clogging of components in automatic equipment and keeps the end product safe.

4.Electronics, semiconductors
Production of printed circuit boards, integrated circuits, various circuits, piezoelectric, crystal, quartz, ceramic magnetic materials, base substrates for printed circuits, special materials for electronic functional processes, electronic adhesive (tape) products, electronic chemical materials and parts, etc. process requires compressed air
