Role of filter in compressed air system
The estimated amount of suspended dust in our atmosphere at any given point of time is approximately 26million tons. 80% of these particles are smaller than two microns in size. These solid, liquid and oil contaminants present in atmospheric air after compression pollutes the compressed air to a considerable degree. These contaminants added with further substances originating from the compressor, pipelines and receivers further affect the quality of air. This creates an abrasive mixture which causes damage to machineries, tools and the end product. Thus, filtering compressed air to the required purity is essential for any industrial process to maintain uninterrupted production & achieve improved productivity.
Puro series filters in combination with the necessary dryer treat the compressed air to meet the stringent requirement of today’s high productive critical industrial processes and the requirements stipulated in ISO 8573-1:2010.
Design Compressed air System (CAS) with Absolute series filters:
Contaminants present in compressed air can be grouped into 8 different categories which can be removed by combination of different purification techniques. Below table gives a brief idea about different type of contaminants and their purification techniques.
