Separators and filters are basic requirements of a compressed air system. The question is, not therefore, why filter? But how should it be filtered. The separation and filtration systems used today for compressed air purification are subdivided into four main groups:
- Gravity Separation
- (pre-filtration)
- Coalescing
- Adsorption
In the following, only a brief overview of these mechanisms is provided. A more detailed explanation is provided in the subsequent sections.
