Compressed air may come into direct or indirect contact with food. When this happens, for example during

production or processing, this requires a much higher level of contaminant control. Particular attention

needs to be given to contaminants added during the compression and the distribution process, such as bread

packaging, fluidized bed in the transfer of flour from a tanker etc.

Recommendations:

• No contact: Air purity class ISO 8573-1:2010 [1:4:1]

• Contact: Air purity class ISO 8573-1:2010 [1:2:1]

The filters comply with the bacteriological filtration grade and the British Compressed Air Society (BCAS)

Food Grade Compressed Air Code of Practice.

3.4 ISO 12500

ISO 12500

ISO 12500 has been introduced specifically to test purification equipment for compressed air and

complements ISO 8573.

ISO 12500 currently consists of:

• Part 1: Oil aerosol filters

• Part 2: Oil vapor filters

• Part 3: Particulate filters

• Part 4: Water removal

ISO 12500-1:2007 - Testing of Coalescing filters

ISO 12500-1:2007 provides a set of standardized conditions with which coalescing filters should be tested

in order to show their filtration performance in accordance with ISO 8573-1:2010. The testing will provide

the user with an oil aerosol carry-over figure in mg/m

and saturated (or wet) pressure drop in mbar. This is

the filter performance at the reference conditions and can be used for benchmarking purposes.

ISO 12500-3:2009 - Testing of Dust removal filters

ISO 12500-3:2009 provides a guide for choosing an appropriate method of determining the solid

particulate removal efficiency rating by particle size. Measurement methods are recommended based on the

size range of the particulates that the filter being tested has been designed to remove. The test is performed

as a type-test on filters as being representative of a range.
