Why does compressed air need to be purified?
In addition to environmental pollution, the compression process itself also adds new pollutants to the air flow, such as oil vapor (caused by compressor lubrication) and particles from rust and corrosion of tanks and pipelines. Compressors alone are only able to remove coarse particles, and the rest of the impure particles remain in the compressed air, which will be disastrous if there is no filtration.
Consequences of not using a microfilter
The presence of impurities such as water, oil and suspended particles causes serious damage to industrial infrastructure:
- Corrosion of pipes: Water and humidity cause rusting of the piping system and lead the rust particles to the consumer devices.
- Damage to precision instruments: Pneumatic equipment and sensitive valves are very vulnerable to particles and oil, and their useful life is greatly reduced. Unwanted stops and expensive repairs.
- Contamination of the final product: In industries such as pharmaceuticals and food, the contact of contaminated air with the product can discredit the entire production line.
Examining the specialized grading of microfilters
- AO grade (general prefilter): This grade has the ability to absorb water and oil particles up to 0.1 micron. AO grade is known as one of the most important and practical grades, which is usually installed before more accurate microfilters to reduce the main pollution load. AA grade (accurate filter): This grade has the ability to absorb very fine water and oil particles up to 0.01 micron. The use of this grade is mandatory for industries that need extremely clean air.
Critical applications of clean compressed air
In many areas, the use of pure compressed air is not a choice, but a necessity:
- Hospitals and medical centers: for the breathing of patients and the operation of operating room equipment.
- Pharmaceutical industries: preventing the combination of suspended particles with sensitive drugs.
- Food and beverage industries: maintaining the health and hygiene of consumer products.
- Industrial painting: preventing the formation of bubbles and impurities on painted surfaces.
Conclusion and importance of system protection
The air that is compressed in the compressor, due to the environmental factors and the working conditions of the compressor itself, usually has a significant percentage of pollution. To increase the efficiency and also to protect the consumer devices in the industries, it is necessary to have completely clean and pollution-free air.
Using the basic filtration system prevents impurities, oil vapor, suspended particles and bacteria from entering the consumer system. By investing in high-quality microfilters, you will not only prevent pipes and valves from rusting, but also dramatically increase the life of your pneumatic equipment.
