Efficient oil-free air compressor series has a variety of types, each has its own characteristics and advantages, the following are some common efficient oil-free air compressor series and their characteristics:
Oil-free screw air compressor:
Working principle: Similar to the principle of oil injection screw air compressor, but the air path and oil path are separated, and the air is compressed through the rotating mesh of the Yin and Yang rotor.
Advantages: It can provide stable and large amount of compressed air, suitable for the scene with gas consumption of more than 8 cubic meters per minute; With high operating efficiency and reliability, the maintenance cycle is relatively long; It can provide high-quality oil-free compressed air to meet the needs of industries with strict air quality requirements, such as pharmaceutical, hospital, food, industrial products and other industries.

Oil-free piston air compressor:
Working principle: The reciprocating movement of the piston in the cylinder is used to compress the air.
Advantages: simple structure, convenient operation; The price is relatively low, suitable for budget limited scenarios; Small size, easy to install and move, suitable for relatively small gas consumption scenes, gas production generally does not exceed 600 liters/minute, the pressure is about 3-8 bar.

Oil-free scroll air compressor:
Working principle: The air is compressed by the relative movement of the dynamic and static scroll disks. There is no direct contact between the dynamic and static scroll disks during operation, which reduces friction and wear.
Advantages: Smooth operation, very low vibration and noise; Compact structure, small footprint; Low energy consumption and high energy efficiency ratio; Can provide pure oil-free compressed air, suitable for laboratories, hospitals and other places with high noise and air quality requirements.

Oil-free centrifuge:
Working principle: Rely on high-speed rotating impeller to centrifugal compression of air.
Advantages: Gas production is very large, suitable for large gas consumption enterprises, such as large chemical, steel, electric power and other industries; High operating efficiency, able to maintain high energy efficiency under large flow rates; It has good stability and reliability, and relatively low maintenance cost.

Oil-free water lubricated air compressor:
Working principle: Pure water is used as lubricant to replace traditional lubricating oil to achieve oil-free lubrication.
Advantages: fundamentally solve the problem of lubricating oil pollution to the environment; It has the advantages of simple structure, compact, low speed, low vibration noise, low exhaust temperature, high thermal efficiency, stable and reliable performance, etc. Low specific power, good energy-saving effect; The machine has few consumables, only air filter and water filter, and the maintenance cost is low.
