In fact, they are so small (microorganisms range from 0.0.4 µm to 4 µm) that they can’t be caught by an inlet filter.īecause they are living organisms, they would multiply if the conditions are right, such as in non-dried compressed air. After all, one cubic meter of ambient air can contain more than 140 million particles – from dust to microorganisms like bacteria, viruses and bacteriophages. For example, the oil and moisture in your compressed air can allow the microorganisms contained in the intake air to grow and thrive. In combination, however, they can be even worse. Individually, each of them can negatively impact your system. Impact the integrity and quality of your end products Negatively impact your air-powered equipment Reduce the performance of your compressed air system itself The contaminants can harm your production in three main ways. Sterilization must be performed frequently to maintain good air quality. The sterile filter must be fitted in a filter housing that allows in situ steam sterilization or that can be easily opened. The most effective treatment involves drying air to a relative humidity of <40% (this can be achieved by using any type of dryer) and fitting a sterile filter in the system. Oil and other contamination act as nutrients and allow micro-organisms to flourish. Investigations have established that micro-organisms thrive in compressed air systems with non-dried air at high humidity (100%).
Despite their size, these micro-organisms are a serious problem in many industries, because as 'living' organisms they are able to multiply freely under the right conditions. Contamination smaller than 1 µm diameter and, consequently, micro-organisms can pass easily through the compressor inlet filter. Typically, bacteria can be as small as 0.2 µm to 4 µm and viruses from 0.3 µm to as small as 0.04 µm. Micro-organisms are extremely small and include bacteria, viruses and bacteriophages. Micro-organisms can germinate through the filter walls and therefore exist in the same concentrations on the inlet as well as the outlet sides of the filter. The situation is complicated further as gases and aerosol can be concentrated into droplets (through concentration or electrical charging) even after passing several filters. Nevertheless, to have pure compressed air, bacteria growth after the filter must be kept fully under control. A filter positioned directly after the compressor can eliminate these risks. This can result in the growth of micro-organisms. From that point, the particles spread throughout the pipe system and mix with the water and oil residue and pipe deposits. More than 80% of the particles that contaminate compressed air are smaller than 2 µm in size and can therefore easily pass through the compressor's inlet filter. While air quality is not as important for some processes, it is crucial to applications in the food & beverage and pharmaceutical sectors, where bacterial growth would be particularly harmful. This is especially problematic in applications in the food and beverage and pharmaceutical sectors. In addition, it could lead to bacterial growth, which could adversely impact the quality of final products. If the moisture is not removed, it can reduce the service lives of pneumatic equipment through corrosion. It is the temperature at which the compressed air is still able to handle its water vapor content before the moisture forms condensate. The water content is measured in terms of the dewpoint. This water vapor is the most prominent contaminant in compressed air in total volume terms and it forms most of the liquid contamination that can be found in the air system. It enters the compressed air piping system through the intake in the form of water vapor. Example: effect add_deposit = d_black_soilĬan be removed with the effect remove_deposit = command to remove modifiers from planets.Then there is the moisture contained in our ambient air. Planetary features Ĭan be added with the effect add_deposit = command combination to add modifiers to planets.
