Screw Compressor Electric Industrial Oil Free Low Pollution Energy-Saving With Low Noise

Generally, oil-free air compressors contain no oil at all. What is truly oil-free is a completely oil-free air compressor. An air compressor lubricated with water is a real oil-free air compressor. Generally speaking, oil-free air compressors contain very little oil. So, what is the difference between an oil-free air compressor and an oil-filled air compressor? The following Copco has compiled relevant content to share with you.

The difference between an oil-free air compressor and an oil-filled air compressor:

1. Different materials: The oil-free air compressor itself does not contain oily substances, which avoids the pollution of the terminal equipment by the oil machine. The material of the oil-air compressor itself contains oily substances, which will pollute the terminal equipment.

2. Different service life: The oil-free air compressor uses a heat-resistant piston, so that the bearing grease will no longer be lost due to high-temperature conduction and radiation, which greatly prolongs the service life of the oil-free air compressor. The oil-air compressor has no heat-resistant piston, and the sealing grease is easy to lose, resulting in dry wear damage to the bearing, and the life of the oil-air compressor is short.

3. The working principle is different: Oil-free air compressors do not involve oil in the operation process. Whether it is an oil-free piston machine or an oil-free screw machine, a large amount of high temperature will be generated during operation. If the air compressor oil is involved, the high temperature generated during the compression process of the air compressor will be taken away, thereby cooling the machine.

4. The exhaust is different: oil-air compressors are lubricated with resin materials, and the final exhaust does not contain oil. Oil-air compressors are lubricated with oil, so the final discharge contains oil.

Key Product Features:
 

1. Guaranteed gap seal
Improve the meshing accuracy between the star wheel and the screw, overcome the low viscosity characteristics of water, and be close to isothermal compression to the greatest extent, and pursue high compression efficiency; the water-lubricated single-screw meshing line adopts "suspension meshing" technology and unique processing special machine processing solution ; Aerospace-grade stainless steel rotor and hydrophilic PEEK star wheel perfectly match.

2. Bearing mechanical seal
The patented mechanical seal technology of Grankline is used to ensure that the compressed air is 100% oil-free; after long-term tests, the mechanical seal technology adopted has a service life of more than 20,000 hours.

3. Guaranteed gap seal
The metal used for the host is made of special stainless steel, which has strong corrosion resistance and wear resistance; the whole system is designed with stainless steel; the system comes with an intelligent device for water purification.

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
