Reasonable Matching of Aftertreatment Equipment for Air Compressors

Different enterprises have varying requirements for compressed air quality, which leads to different configurations of aftertreatment equipment for screw air compressors. 

Higher standards for compressed air require more stages of filtration, while lower requirements allow simpler aftertreatment setups. 

This article introduces the performance of different configurations and how to reasonably match air compressor aftertreatment equipment according to practical application requirements.

Air compressors generate compressed air containing oil, moisture and various airborne contaminants. The oil-gas separator separates compressor lubricant from air, 

yet a small amount of oil will still be entrained with the airflow. Therefore, aftertreatment equipment such as refrigerated air dryers, filters and water-oil separators need to be equipped. 

Refrigerated air dryers mainly remove moisture, while precision filters are used to eliminate oil and airborne impurities.

Compressed air filters are deployed to remove contaminants inside compressed air systems, including iron filings, dust, oil aerosols and hydrocarbon mist. 

They supply high-quality compressed air that meets operational demands and serve as essential filtering equipment for factories and laboratories.

A typical filter consists of a top cover, middle shell and bottom shell. Both the top cover and middle shell are provided with two round holes. 

Two aluminum barrels are installed side by side between the corresponding holes to form the first and second filter chambers. 

The bottom of the lower shell is connected to a drain device via a connector, and a float ball is arranged inside the drainer.

After being processed by the above air compressor aftertreatment equipment, the compressed air becomes highly clean. 

Direct application of this moisture-free and oil-free compressed air brings significant benefits to factory equipment.
