(1) Unlike oil aerosol removal filters which are changed annually to guarantee compressed air quality, the lifetime of an oil vapour removal filter can be attributed to
various factors and require more frequent changes. Factors affecting the lifetime of adsorption filters are:
Oil vapour concentration -
The higher the inlet concentration of oil vapour, the faster the activated carbon capacity will expire.
Bulk oil - Adsorption filters are designed to remove oil vapour and odours, not liquid oil or aerosols. Poorly maintained or non-existent pre-filtration will cause the OVR filter
capacity to quickly expire.
Temperature - Oil vapour content increases exponentially to inlet temperature, reducing element life. Additionally, as temperature increases, the adsorption capacity decreases,
again reducing element life.
Relative Humidity or Dewpoint - Wet air reduces the adsorptive capacity of the carbon.
Compressor oil changes - When compressor oil is changed, the new lubricant burns off “light ends” which increases the oil vapour content for hours or even weeks afterwards.
This increase in oil vapour content is adsorbed by the OVR filter, significantly reducing its adsorptive life.
OVR performance is based upon a maximum oil vapour inlet concentration of 0.05mg/m
3
, and a pressure dewpoint of -40
o
c PDP.
These elements should be replaced upon detection of vapour, odour or taste.
