Air Line Filtration
- 23 -
A compressed air system is typically contaminated with impurities which could ultimately cause serious problems
where clean air is critical. As noted in the section dealing with the Refrigerated Air Dryers, applications such as the the
autobody refinish industry and HVAC installations require compressed air that is free of contamination.
Impurities that can be found in a compressed air system may include solid particles, water droplets, and oil aerosols
and vapours. With suitable Air Filters in the system, and paying close attention to both the type and size (of Filters)
required, your Customer can obtain the air quality that their application demands.
Please be advised that in areas and applications where air quality is of great importance, suitable filtration in the air
system coupled with a properly sized Refrigerated Air Dryer will provide the best possible compressed air. And, as with
all compressed air componentry, though the correct selection of the components is important, maintenance is crucial
in ensuring both suitable air for your needs, and achieving long life from your equipment.
To follow are the four basic Air Line Filters that Devair has available in their product line, listing a brief outline of their
particular application. Also, on the page to follow, please find a chart outlining the correct size of Filter to use based on
your Compressor HorsePower and/or CFM requirements, as well as a listing of various relevant specifications.
The current line of Compressed Air Filters allows the (4) series of Filter Elements as noted below to be installed in one
Cannister, namely the ‘SAF-C’.( Please use the a suffix reflecting the volume of air.)
* Removes large liquid loads and all solid particles three microns and larger
* Removes 99% of liquid water
* Generally used in air systems without Aftercoolers or Refrigerated Air Dryers
* Removes all liquid water, oil aerosols, and solid particles one micron and larger
* Used as a general Filter for shop air, a pre-filter for high efficiency Filters, an after-filter for Pressure Swing `
Desiccant Dryers, or a ‘point of use Filter on systems using Aftercoolers or Refrigerated Air Dryers
* Removes 99.99% of oil aerosols for virtually oil-free air, as well as solid particles 0.1 microns and larger
* Generally used with oil-lubricated air compressors where oil-free air is critical, ie spray and powder painting, plastic
moulding, instrumentation and control applications
* Removes oil vapour and odour
* Generally used in food and drug packaging where compressed air may come into contact with the product
‘SAF-S’ Series of Prefilter Moisture Separators (5 micron).
‘SAF-A’ Series of Coalescing Filters (1 micron).
‘SAF-E’ Series of High Efficiency Coalescing Filters (.1 micron).
‘SAF-V’ Series of Activated Carbon Oil Vapour Removal Filters.
