Filter Media Versus Depth Efficiency - Gereral Information
The more dense the media and the deeper the flow path of the fluid, the higher the efficiency rating will be. Delta-P (pressure across) the filter, which affects flow rate.

To determine the proper element for the application, you must determine the type and viscosity of the fluid you will be filtering and what you want to achieve. For example: A thin viscosity fluid, such as kerosene or diesel fuel with little contamination, should be filtered with our #2 media and a 10" flow depth element at a Delta-P of 20 to 30 PSI. Using our C-1000 filter housing, you would select element #6522. For the same fluid with very high contamination you would select our #6524 element, this is our #2 media with a flow depth of 5". Another choice would be our #6526 element, which is our #2 media with a 3" flow depth. Using the same fluid and the same Delta-P, you will have a higher flow rate and a higher micron rating. See example below:

Example:
Element #6522 (10 depth) with a Delta-P of 30 PSI will flow approximately 1.5 G.P.M. - Micron rating at less than 1 micron.
Element #6524 (5" depth) with a Delta-P of 30 PSI will flow approximately 2.5 G.P.M. - Micron rating at less than 2 microns.
Element #6526 (3" depth) with a Delta-P of 30 PSI will flow approximately 3.5 G.P.M. Micron rating at less than 5 microns

If you change the Delta-P, which will effect your flow rate, you will change your efficiency rating. Typically, the lower the Delta-P, which results in a lower flow, will give you a higher efficiency.

Thicker fluids require a less dense media and less depth to allow thick fluids to flow. Our most practical element for this fluid would be our #6546 or#6548 element.

DEFINITION OF MEDIA TYPES

FILTER MEDIA #1
This filter media is used to filter water and water based liquids such as water glycol hydraulic fluids, some machine tool coolants, cooling tower water and many aqueous fluids. It will retain a small amount of oil from water. This micron rating is from 1 to 10 microns, depending on the flow depth selected. It is available in flow depth from 2 to 10 inches.

FILTER MEDIA #1A
This filter media is also used for water and water based liquids. #1A media can be used in any application that #1 media is used plus liquids that are made up of an oil emulsion. The major differences between #1 and #1A media is that #1A media does not retain oil from water, has a greater dirt holding capacity and has a higher micron rating. The micron rating is from 30 to 50 microns, depending upon the flow depth selected and the fluids being filtered. It is available in flow depth of from 2 to 10 inches.

FILTER MEDIA #2
This is our most efficient media. The micron rating is from less than 1 to 5, depending on the flow depth selected. These elements are used when filtering light viscosity fluids. Fluids such as, but not limited to, solvents, kerosene, gasoline, diesel fuel, transformer oil, and light viscosity oils. Phosphate-ester fluids may also be filtered with this media. It has excellent water removal characteristics. It is available in flow depths of from 2 to 10 inches.

FILTER MEDIA #3
The micron rating is from 1 to 10 microns, depending on the flow depth selected. It is our most popular element for filtering hydraulic oil; viscosities from 100 to 500 SUS at 100 degrees F. This media may be used in the same applications as our #2media. It has excellent water removal characteristics. It is available in flow depths of from 2 to 10 inches.

FILTER MEDIA #4
The micron rating is from 5 to 10 microns, depending on the flow depth selected. Typical applications for this media would be lube oils, such as engine crankcase oil, gear oil, machine tool cutting oils, with temp. under 270 degrees F, and the thicker viscosity hydraulic oils. This media can be used in the same applications as our #2 and #3 media with exception of phosphate-ester, but will not be as efficient, especially on the very thin fluids, because it is not as dense and therefore will have a lower Delta-P or less resistance to flow. This media also has excellent water removal characteristics. It is available in flow depths of from 2 to 10 inches.

FILTER MEDIA #5
This media was designed to filter water and water based fluids such as HWB (high water base) hydraulic fluids, and machine coolants (water base) rinse water, cooling tower water and many other aqueous fluid applications. This media absorbs everything. The micron rating for this filter media is from 1 to 10 microns. This media will retain a small amount of oil from water. It is available in flow depths of from 2 to 5 inches.

FILTER MEDIA # 6
This media has a micron rating of from 10 to 30 microns. It has a very low Delta-P characteristics, therefore it can be used on highly contaminated oils. Typical applications would be gear oil, die lube oil, and drawing compounds, as well as quench oil up to 400 degrees F. It has good water removal characteristics.

FILTER MEDIA #8
This media works well in water based fluids. Typical applications would be certain machine tool coolant, caustic bath cleaning systems, condensate from air compressors and numerous other special applications. It has good oil removal characteristics. The micron rating for this media will vary, based on the application it is used in. Generally it would be from 5 to 50 microns.
