Depth elements are used in low flow filtration systems such as applications containing soft contaminants, sludge, slime, or waxes. Fluitek depth elements are most commonly used to clean or recycle hydraulic oil, compressor oil, gear oil, quench oil, or various other fluids with off-line or side-stream kidney loop systems.

This series of elements is available in several different sizes and forms. There are a lot of different options of medias including cellulose and synthetic fiber blended medias. Fluitek depth filters are available in an efficiency range from 1 - 150 micron and up to a 350°F max temperature rating. The prime advantages of depth filtration elements are high dirt holding capacity, long filtration cycles, and high retention of small particulate in polishing applications.
