Providing Compressed Air Oil Monitoring Filters

Your Source for Compressed Air Oil Monitoring Filters

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.

Removing and Monitoring Oil Aerosol Carryover

Pioneer’s oil air filters follow a six-step process to remove and monitor oil aerosol carryover:

  1. The separation area works by impingement, direction change, and expansion; it separates dirt particles and liquid droplets.
  2. The oil pre-filter removes dirt particles to keep the coalescer operating at peak effectiveness.
  3. The coalescer removes liquid oil and oil vapors.
  4. The Coalescer Plus filter material turns from white to a bright red as it detects oil on the filter.
  5. The After Filter element prevents the migration of coalescing media.
  6. The Final Filter ensures the quality of outgoing air.

Absorbing and Monitoring Oil Vapor Carryover

The six-step process for absorbing and monitoring oil vapor carryover is:

  1. The separation section utilizes impingement, direction change, and expansion to separate particles and liquid particles.
  2. The oil pre-filter then removes dirt to maintain the air filter‘s performance.
  3. Activated carbon is then used.
  4. The Coalescer Plus gradually changes from white to bright red as it absorbs oil-based aerosols.
  5. Pioneer’s After Filter prevents the migration of coalescing media.
  6. The Final Filter ensures the safety of outgoing air.

Point-of-Use Protection From Dirt, Oil, and Moisture

These oil air filters follow a seven-step process:

  1. Separating particles and liquid droplets by impingement, direction change, and expansion. 
  2. Ensure the effectiveness of the coalescer through the use of an oil pre-filter 
  3. The coalescer removes oil vapors and liquid oil.
  4. The air goes through an intermediate air filter cleaner.
  5. Activated alumina is then used to remove impurities.
  6. A blue indicator desiccant turns pale pink when saturated.
  7. The final Filter ensures the quality of outgoing air.

Features of Pioneer’s Oil Air Filters

Our top-quality compressed air oil monitoring filters have many beneficial features, including:

  • Multi-step separation
  • Visible warning
  • The Low-Pressure Drop Series has a nominal pressure drop of 2-6 PSIG. To provide equivalent filtration with conventional filters, you need several with a total pressure drop of 5-10 PSIG.
  • Highly efficient adsorbent media
  • Two Safety Options—an expanded metal safety shield is standard in filters with transparent poly-carbonate housing. A metal housing with dual sight glass is available for applications where poly-carbonate housings may not be safe.
  • Dual-sight glass for filters encased in a metal housing allows light to enter one port as you look through the other.
  • The back-saver feature for larger filters (2″ [50.8mm] NPT and up) has a built-in lift mechanism to avoid back injury and reduce maintenance time.
  • Multi-step separation provides maximum protection.
