Solutions to improve air quality Guidance on the treatment of compressed air

1 m3 of

untreated air
contains up to 180 million particles of dirt, 50 – 80% water vapour and oil in the form of unburnt hydrocarbons at between 0.01 mg/m3 and 0.03 mg/m3.

Compressed air is used today in diverse industrial sectors. The multitude of applications range from untreated blow-down air to absolutely dry, oil-free and sterile compressed air for the pharmaceutical and food industry. This rich spectrum of applications demands individual levels of compressed air treatment, designed precisely for each application. 1 m3 of compressor intake air can contain up to 180 million particles of dirt. Besides these particles of dirt, the intake air can also contain 50 – 80% water vapour and oil in the form of unburnt hydrocarbons from machinery and waste gases. In addition, tiny amounts of lubricating oil and dust from the compressor can get into the compressed air network. When compressed to 10 bar for example, the concentration of these harmful substances increases eleven-fold, i. e. 1 m3 of compressed air can contains up to 2 billion particles of dirt. Depending on the application, these particles of dirt will have to be removed until the compressed air becomes absolutely dry, oil-free and sterile. The table on page 3 gives a summary of levels of achievable air quality. However, it can only show an overview of the possibilities. When choosing a treatment system, the starting point must be to accurately determine the use of the air – the application. This establishes the required quality for the compressed air.

Compressed air treatment requires: additional investment cost maintenance work on treatment systems

But correct compressed air treatment: increases the service life of compressed air operated equipment improves the quality of your products increases your competitiveness increases your company’s profitability reduces the risk of operating problems reduces repair costs for compressed air operated equipment reduces purchasing costs for piping systems At the planning stage, the experienced BOGE team can advise you about the type of compressed air treatment most suited for your application. This support protects you from installing a higher – or lower – level of air treatment equipment than necessary. BOGE can provide you with the optimum solution for your application, both from the point of view of cost and quality.
