To Select the Filter Grade:

• Use the 40 mesh or 80 mesh (200 micron) grade when heavy solids loading is expected, or when only relatively coarse filtration is required - for example, in cooling water loops
• Use the 130 mesh (100 micron) grade to remove essentially all visible solids from the liquid.
• Use the 300 mesh (50 micron) grade to protect finer disposable filters or carbon cartridges

How to Select the Correct Size Filter Assembly

Keller supplies filter systems for line sizes from 3/8" to 2", with flow capacities to 150 gallons per minute. To select the correct size Keller filter assembly, specify the filter assembly with port size equal to the size of the line on which it will be installed. The flow rate in the line will likely be less than the rated flow of the filter at 2 psi pressure drop (see chart below), and therefore the initial pressure drop will likely be less than 2 psi.

* #038A and #075A also available with polypropylene bowl; substitute “B” for “A” in ordering information.
