Case Study - Hydraulic Depth Filters

FILTERS that use a porous medium and catch particles using throughout the medium and not just the surface or layer. Medium can be fibrous cellulose, polypropylene along with base paper or flat filter cloth. It normally will have an inner core an outer core, in some case, a shoot to encase the media.
There is normally a base paper or filter cloth to act as a bed to flow of liquid through the media.
Filter extraction hooks /ribbon/or eyelet help removal of filter after it has choked or used.

Depth Filters

  • CELLULOSE PAPER DEPTH FILTERS 
  • POLYPROPYLENE DEPTH FILTERS
  • CELLULOSE PAPER DEPTH FILTERS 

Developed to increase oil change intervals half a decade back-the method is used worldwide for ultrafine cleaning of machine oils.
Hydraulic oil cleaning is blessed with usage of depth filtration, keeping machines well oiled and never prone to failures.
Long slender fiber pulp are used for making filter paper used for depth filters. Long fibers help absorb moisture, and the capillary action of the fibers help retain moisture in media. The round coil similar to a paper roll from a depth and various level of compression on outer core enable multi layer filtration assisted by base paper, skirting or other arrangement as per manufacturer designs.

The amount of surface area directly correlates to the solids loading capability and related pressure drop. Depth Filtration refers to a thicker media or multiple layers of media, forming a torturous path to retain particles.
