nnnnDF-THREE SERIES
nnnnCompressed Air & Process Filtration
nnnnDonaldson® Three-Stage Filters are designed for
nnnnthe removal of oil aerosols, oil vapors, and solid
nnnnparticles from compressed air and gases with a
nnnnsingle filter element. The filter element combines
nnnnthree purification stages in one filter:
nnnn1. Coalescence filter for the removal of oil/water
nnnnaerosols and particles
nnnn2. Activated carbon adsorber (packed bed) for
nnnnthe removal of oil vapors and other
nnnnhydrocarbons
nnnn3. High performance particle filter to achieve
nnnnClass 1 quality according to IS08573-1:2010
nnnnThe three-stage filter is ideally suited as a final
nnnnfilter when the highest quality of compressed air
nnnnis required. By combining several purification
nnnnstages in only one filter housing, the DF-Three is a
nnnncompact solution for a limited space requirement.
nnnnThe Economizer is intergrated into the DF-Three
nnnnfilter housing and signals when a filter exchange
nnnnis recommended. Monitoring of changes in
nnnndifferential pressure and service time ensure
nnnnoptimal performance of the DF-Three.
nnnnWith three sizes, the three-stage filter covers a
nnnnperformance range up to 65 scfm flow rate at an
nnnnoperating pressure of 100psig.
