Oil air compressor refers to the use of lubricating oil (synthetic oil or semi-synthetic oil) in the air compressor system to lubricate the machine and dissipate heat. This kind of air compressor, the compressed air will have a certain amount of lubricating oil, that is, the post-processing equipment is used for filtering, but it will still have a small amount of lubricating oil, so it is not suitable for some working conditions.
Oil-free air compressor, there are 2 kinds:
in the air compressor system, no lubricating oil is added, pure water is used for lubrication, and no lubricating oil is involved in the operation of the air compressor. Therefore, the compressed air has no lubricating oil, so it is called an oil-free air compressor.
In the air compressor system, lubricating oil is involved in the operation of the air compressor, but the lubricating oil is isolated from the compression zone by means of complete isolation. The lubricating oil is only responsible for the lubrication protection of the bearing and does not participate in the compression.
Note: The compressed air of an oil-free compressor is not 100 percent oil-free. Because the air contains trace amounts of oil, in some places, the oil content in the air is higher. Therefore, even if the oil-free air compressor is used, the compressed air still needs to be processed.
All oil-free air compressors do not need to add lubricating oil, rely on high speed or water lubrication. The compression of the discharge can be done without lubricating oil particles.
The universal micro-oil air compressor relies on the special air compressor lubricating oil as sealing, cooling, cleaning, heat dissipation, etc.
The following from the working principle of screw air compressor to explore the difference between micro oil and oil free screw air compressor:
micro oil screw air compressor working principle:
micro oil screw air compressor shell has a pair of precision machining of the mutual meshing of the female and male rotor. The motor drives the male rotor through the transmission device, and then the male rotor drives the female rotor. The compressor oil injected into the casing is mixed with air and effectively compressed between the cogging grooves of the rotor
oil free screw air compressor working principle:
water-lubricated single screw air compressor is an oil-free air compressor series. Granklin Group uses water as a lubricant to fundamentally solve the problem of environmental pollution caused by lubricating oil. Compared with other oil-free air compressors, it has the advantages of simple and compact structure: low speed, low vibration and noise: low exhaust temperature: high thermal efficiency: stable and reliable performance, and low specific power. It is the development trend of new oil-free oil machines.
Oil-free water-lubricated air compressor uses water as lubricating medium to compress air, providing high-quality 100% oil-free compressed air, no pollution, no special treatment of water discharged, in line with environmental protection requirements. In the oil-free compressor market has been recognized by the majority of customer groups.

Compressors are classified according to different structural forms as follows: According to their principles, they can be divided into: reciprocating (piston) compressors, rotary (rotary) compressors (turbine, water ring, turbine) compressors, and axial flow Compressors, jet compressors and screw compression
Screw air compressors are more common in the air compressor market, gradually replacing piston machines. Basically the piston machine has been taken off the market. But how do you know the price of an air compressor? Users who do not understand must bear the burden.
For enterprises to choose low energy consumption, environmental protection of the air compressor is a must, now so fierce competition, the need to control every aspect of enterprise production, in order to bring profits. Permanent magnet variable frequency air compressor has the characteristics of environmental protection and energy saving, which is well known, but the price of equipment with good performance and environmental protection must be expensive?

Shanghai Granklin Group produces water-lubricated air compressors. Water-lubricated air compressors do not use lubricating oil. Water is used as a lubricant with less pollution, better environmental protection and cleaner exhaust gas. Today's society promotes environmentally friendly travel. If the distance to work is not too far, more and more people choose to walk and ride bicycles as their main mode of travel. Environmental protection is the eternal theme of life. A high-quality environmental protection air compressor will bring convenience and quickness to your work.
