The specification of the most appropriate air treatment can be a complex task and this brief overview only illustrates the basic principles to consider. BCAS recommends that users consult their compressed air supplier for expert advice

At a glance – Key questions

For each air treatment technology, there will be a variety of questions to ask. For example, when choosing filtration, you will need to check:

Has it been sized correctly? Can the filter handle the compressed air flow rate at the minimum system pressure and maximum system temperature?

What grade of filtration is needed? Is single or multi-stage filtration required? Are you specifying at the compressor house or point of use?

What budget is available? Filters are often seen as a commodity and purchased on price, but is it worth compromising on performance? Has a total cost of ownership approach been taken, rather than just focusing on the initial purchase price?

Detailed guidance can be found in the BCAS ‘Filtration and Drying of Compressed Air - Best Practice Guide 104.
