Not all compressed air filters are the same. There is a large range of products available many of which are sold on the basis of low price but offering inferior performance and short lifetimes. It is important that the performance of filters used to purify compressed air is validated in accordance with ISO12500.
ISO12500 specifies the testing procedures for testing compressed air filters to determine the efficiency in removing oil aerosols, oil vapour and particles. Safewell Solutions is the authorised oil and gas industry distributor for Donaldson Filtration Solutions, a global company with leading edge filtration products which have been validated to have a retention rate in accordance with ISO12500-1.
