Abstract
Some embodiments relate to a filter material for coalescing a dispersed phase in a continuous phase. The filter material has binder fibers and irregular rayon fibers distributed among the binder fibers. The filter material lacks non-fibrous resin. Some embodiments relate to a filter assembly. The filter assembly has a particle filtration layer, a coalescing layer downstream of the particle filtration layer, and a growth media downstream of the coalescing layer. The coalescing layer is coupled to the particle filtration layer. The growth media has irregular rayon fibers and binder fibers distributed among the irregular rayon fibers. The growth media lacks non-fibrous resin.
Claims16
A filter material comprising:
- binder fibers;
- irregular rayon fibers distributed among the binder fibers;
- and
- fibrillated rayon fibers, wherein the filter material lacks non-fibrous resin, wherein the filter material is 30% to 75% by weight total rayon fibers including at least the irregular rayon fibers and the fibrillated rayon fibers.
A filter assembly comprising:
- a particle filtration layer;
- a coalescing layer downstream of the particle filtration layer, wherein the coalescing layer is coupled to the particle filtration layer;
- and
- a growth media downstream of the coalescing layer, the growth media is filter material comprising:
- irregular rayon fibers;
- binder fibers distributed among the irregular rayon fibers, wherein the filter material lacks non-fibrous resin;
- and
- fibrillated rayon fibers, wherein the filter material is 30% to 75% by weight total rayon fibers including at least the irregular rayon fibers and the fibrillated rayon fibers.
