Added by the compressor installation through oil lubricated compressors (oil), adsorption dryers and activated carbon filters (dirt), piping network and vessels (pipescale).
Trash in, trash out: oil vapors from car exhausts and industrial processes, atmospheric dirt and micro-organisms get sucked in by the compressor. As with water, their concentration – and thus importance – increases significantly after compression.
What problems can the contaminants cause?
Damaged production equipment, leading to inefficiencies and increased costs
Air pollution, creating unhealthy work environments
