Upholding Air Quality of Your Compressed Air System

Air Systems

There are primarily four levels of air quality:

  • Plant air in industrial manufacturing
  • Instrument air in laboratories
  • Process air in pharmaceuticals
  • Breathing air in hospitals

Maintaining the proper quality of compressed air keeps down energy costs and maintenance needs. You should treat compressed air in accordance with its end-use application. Common causes of the decrease in air quality are lubricants, particulates and moisture. That said, below are some equipment to help improve the quality of compressed air.

Maintaining these air treatment equipment is critical in sustaining desired air quality levels. More than that however, it is advisable to get an aluminium pipe supplier for your compressed air system. With aluminium piping, moisture does not build up in your system. This decreases the risk of corrosion, ultimately delivering cleaner air.

Filters

You can use two kinds of filters for better air quality. One removes particulates and is tailored in accordance with your system. Another filter is for filtering out lubricant contaminants. It is especially useful in food production. The reason for this is that there is less tolerance for lubricants.

Dryers

Moisture not only reduces air efficiency but also increases wear on your system. Dryers reduce condensation by lowering the dew point of compressed air. There are three types of dryers: deliquescent, refrigerated and desiccant. Make sure that the dryer you use matches what your air compression system can tolerate. Over-drying air leads to waste of energy.

Aftercoolers

One of the leading ways condensation occurs is when hot compressed air cools when exposed to surrounding temperatures. You can use after-coolers to cool hot air before getting to the end point. This will prevent condensation from forming in the piping. Two types of air coolers are air-cooled and water-cooled after-coolers.
