What removes dust from the air before an air compresser compresses air?

Before air is compressed by an air compressor, dust and other particulates are typically removed using air filters, such as intake filters or pre-filters. These filters can capture larger particles and contaminants, ensuring cleaner air enters the compressor. Some systems may also incorporate cyclonic separators or coalescing filters to further enhance air quality before compression. This process helps improve the efficiency and longevity of the air compressor and downstream tools.
