| <BR> | If the impurities and water from atmospheric air remain in the compressed air the consequences can be unpleasant. This applies to the pipeline and the consumer devices, and products can also suffer if the quality of compressed air is poor. In some applications the use of compressed air without adequate
treatment is dangerous and a health hazard.
Solid matter particles in compressed air
- Wear on pneumatic systems. Dust and other particles cause scuff. This effect is increased i f the particles combine with lubricating o i l or grease to form a grinding paste.
- Particles that are hazardous to health.
- Chemically aggressive particles.
Oil in the compressed air
- Old and different oil in the pneumatic system. Resinified oil can reduce pipe diameters and cause blockages. This increases flow resistance.
- Oil-free compressed air. With pneumatic conveyance, oil can stick to the product being conveyed and thus cause blockages. In the food and pharmaceutical industries compressed air must be free of oil for health reasons.
Water in the compressed air
- Corrosion in the pneumatic system. Rust forms in the pipelines and operating elements and causes leaks.
- Gaps in lubricant films. Gaps in lubricant films lead to mechanical defects.
- Formation of electrical elements. Electrical elements can form when some metals come in contact with water.
- Formation of ice in the pneumatic network. In low temperatures water in the network can freeze and cause frost damage, reduce pipe diameter and block pipes.
