Donaldson Coalescer Filter Assembly

20 scfm - 1500 scfm 0.01 micron

Donaldson DF Filter Assembly ComboOften called the pre-filter since it is placed on the air line just prior to the air dryer, a coalescing filter removes oil, particles and moisture before it can come in contact with the desiccant in the dryer and ruin it.

The Donaldson DF Filters are designed for high quality filtration of compressed air or gas in a wide range of applications. The total filter design concept of the filter combines high performance, efficiency, ease of use, flexibility, and safety.

Features:

  • •   Coalescer Filter Assembly Includes Filter Element
  • •   Particle Removal Rate: 0.01 micron
  • •   Variable Flow Rate: 20 scfm - 1500 scfm
  • •   Available Connection Sizes: 1/4" to 3" NPT threaded
  • •   Long-Term Protection Against Corrosion
