Filter Information

Filtration is the removal of particulate contamination by use of filter media. Particulate contamination can come from many sources. Contaminants are measured in Microns. A Micron is a unit of measurement equal to 39 millionths of an inch. The smallest particle that can be seen by the naked eyes is 40 microns. The most common cause of hydraulic system failures is fluid contamination. 100 gallons of new oil can contain up to 7 grams of contaminants.

In hydraulic systems particles that do the most damage range from 3 to 30 microns. Contaminants can be removed from system fluids by running the fluids through a filter media. Examples of filter media are: cellulose (paper), micro-glass, stainless steel wire mesh, sintered stainless steel, metal fiber felt, and water absorbing. Below are characteristics of some filter media. If you have any questions contact us today
