Cleaning and replacing air compressor filters

air compressor filters

Air compressor filters are devices in air compressors that remove solid dust, oil and gas particles and liquid substances from compressed air. As an important part of the air compressor operation process. Correct and safe use
Air compressor filters not only ensure the service life of the air compressor, but also effectively reduce energy consumption and achieve green energy saving.

How air compressor filters work

The main function of air compressor filters is to enter the oil-containing compressed air generated by the host into the cooler, mechanically separate it into the oil and gas filter element for filtration, intercept and aggregate the oil mist in the gas, and form oil droplets concentrated at the bottom of the filter element and return to the oil return pipe. Compressor lubrication system makes compressor discharge purer.

The air compressed from the screw compressor host head carries oil droplets of different sizes. Large oil droplets are easy to separate through the oil and gas separation tank. While small oil droplets (suspended) must pass through the micron-grade glass fiber of the oil and gas separation filter element. filter material for filtration. After the oil mist is intercepted, diffused and aggregated by the filter material, the small oil droplets quickly aggregate into large oil droplets, pass through the filter layer under the action of pneumatic force and gravity, and settle at the bottom of the filter element.

Cleaning and replacing air compressor filters

The service life of air compressor filters is generally 3000-4000 hours. If the environment is poor, its use time will be shortened. When the lubricating oil consumption of the air compressor increases significantly, the oil filter, pipelines, oil return pipes, etc. should be checked in time to see if they are blocked and cleaned. After cleaning, if the oil consumption is still very large. It means that the oil and gas separator has deteriorated and needs to be replaced in time. When the pressure difference between the two ends of the oil and gas separation filter element reaches 0.15MPA, it should be replaced. When the pressure difference is 0, it means that the filter element is faulty. Or the air flow has been short-circuited. It is also necessary to replace the filter element at this time.
Therefore, choosing the diameter and thickness of glass fiber is an important factor in ensuring the filtration effect.
