• ISO 12500 : as an international standard that regulates the method for compressed air filter test and measurement, it regulates tests on oil, oil vapor and solid particle in filters.
  1) ISO 12500-1 : Oil (oil removal performance test)
  2) ISO 12500-2 : Oil Vapor (oil vapor removal performance test)
  3) ISO 12500-3 : Particle (solid particle removal performance test)

• When differential pressure exceeds 0.3bar, element needs to be replaced. Replacement of element is determined as earlier time between regular replacement period of 1 year and when differential pressure meter indicates red color
• However in case of C Grade, the lifetime of element is expired at 1,000 hours under rated conditions or when an odor is detected at the filter bottom.
