Pioneer Air Systems’s oil air filters play an essential role in protecting the breathing air of a system or environment. When the coalescer media absorbs oil, the element changes color from white to red. As oil saturation progresses, the color gradually rises and becomes brighter. The indicating filter incorporates six steps—separation, oil pre-filter, coalescing, indicator plus coalescing, after-filter, and final filter.
This provides an early indication that your oil air filter needs to be replaced while also monitoring oil carryover. Replacing your monitored oil-free air filters before the red indicator reaches the top prevents downstream compressed air system contamination and keeps clean, dry air flowing throughout.
