Dolomann absolute oil free filter of air compressor:
It is the secondary air/oil separator. Can replace the oil-free air compressor. Air and lubricating oil can be separated, and the air oil content below 0.01ppm, which almost isolates tiny oil molecules, therefore, the discharged air gas is clean and oil-free. The filter material imported from Germany, and developed by Dolomann and has a patent, the patent number: M293077.

The remaining oil and air are absorbed by the Air / Oil separator of the air compressor, so that the oil content of the air is reduced to 0.01ppm, almost reaching the oil-free state, as the gas discharged by "oil-free air compressor" have very low oil and gas content, it could be having the advantages of "oil-free air compressor" by using an absolute oil-free filter installed in "oil-based air compressor." This is the Dolomann exclusive design for re-filtration of Air / Oil separator of air compressor.

The absolute oil-free filter can make the oil-based air compressor achieve the effect of oil-free air compressor, which not only makes clean and oil-free compressed air, but also reduces the harm of its oil mist to the working environment and workers.

Working Principle of Dolomann Absolute Oil-Free Filter:
  • Compressed air enters to the absolute oil-free filter, and passes through the air / oil separator (micron grade glass fiber) to separate lubricating oil from compressed air.
  • The separated fine oil gas is accumulated into large oil droplets, and sent the oil back to the oil filter through the bottom-oil return pipe.
  • These oil drops return to the oil circuit of the air compressor via the oil return pipe, repeatedly used for screw machines of air compressors.

Dolomann absolute oil-free filter is installed between the air tank and dryer, it deals with oil content lower than 0.05ppm, water content oil content down to 0.01 ppm even 0.03ppm, which can reach absolutely oil-free compressor.

Then, the compressed air will be dried by dryer of the air compressor system, and the remaining oil and gas will be absorbed by the precision filter, so that the oil content of the air will be reduced to 0.01ppm, almost reaching the oil-free state. Due to the gas discharged by "oil-free air compressor" have very low oil and gas content, it could be having the advantages of "oil-free air compressor" by using an absolute oil-free filter installed in "oil-based air compressor." This is the Dolomann exclusive design for re-filtration of Air/Oil separator of air compressor.

Features

  • It can produce cyclone and throw the timing of water discharge by using compressed air into absolute oil- free filter.
  • Separate gas adsorption of compressed air and use the rest oil to discharge by gravimetric method.
  • Produce drain by using the float of white iron ball. Easy installation, oil, gas and water can be removed manually as appropriate.
  • Check external pressure difference of separator at any time.
  • Increase the lifespan of precision filter.
  • Prevent the disadvantage of posterior segment of peripheral devices and pipeline when the air compressor discharge lots of oil.
  • Reduce the displacement of posterior segment refrigerated dryer and compressed air impurities clog drainage.
  • Air Oil Content Below 0.01ppm.
  • Air Water Content 0.0137g/M³.
  • Air Dust Content 0.1ppm.
  • Compressed Air Quality CLASS-1.
Needs to Replace Air / Oil Separator Regularly for Oil-based Air Compressor:

Traditional oil-based air compressor must be use lubricating oil, which will produce impurities and oil stains during operation, and the discharged air contains oil, water and impurities in the air, which will accumulate in pipelines and filter elements.
If the Air / Oil Separator is not cleaned and replaced for a long time, it is easy to be blocked by dust and metal debris in the air, which reduces the efficiency of separating air from lubricating oil, discharges air containing impurities and oil stains, and affect the products and working environment of the production line.

The Dolomann absolute oil-free filter can intercept the oil and gas in filter during the operation of air compressor, which can effectively avoid the following three risks:

  • The discharged oil and gas may accumulate on the ground of working environment, which will cause oil stains on the ground and increasing the difficulty of cleaning.
  • The discharged oil mist particles are harmful to human body. By intercepting the oil mist particles during the operation of air compressor, to reduce the discharged oil mist and pollution to the working environment.
  • Oil and gas are accumulated around the factory environment. It is easy to spontaneously ignite and cause fire.

How to stabilize the air compressor system ? and extend the service life of "oil compressor" ?
That is to regularly check and replace the filter and filter element of the air compressor.
The key point is to replace the filter and filter element of the air compressor regularly, reduce the blockage of the internal pipeline, make the pipeline smoother, ensure the normal operation of the air compressor, reduce the energy consumption and prolong the service life. Therefore, for the maintenance of air compressor, if you use oil-based air compressor, it is strongly recommended to install the absolute oil-free filter of air compressor developed by Dolomann, so that it almost has the characteristics of oil-free air compressor.

Functions

Separating the lubricating oil and air of the air compressor, so that the lubricating oil returns to the oil filter, it reduces the air oil content to below 0.1ppm and air dust content to below 0.1ppm, the absolute oil-free filter can make the oil-based air compressor achieve the effect of oil-free air compressor, which not only makes clean and oil-free compressed air, but also reduces the pollution to the factory working environment and prolongs the service life of the air compressor.
