Sock Depth Filters

Sock Depth Filters are used to filter various contaminants from fuels, gasses, amines, lubricating oils and other liquids. The densely packed cotton and/or other organic materials remove hard particles, semi-solids, gums, vanish and acids.

Our unique rolled and layered construction provides improved efficiency and service life. Our patented “Swirl Flow” design has low pressure drop and extraordinary dirt holding capacity. Replacements available for companies such as Jonell, PECO, United Engine Life, and Nelson/Winslow.

Cotton’s fine fiber diameter and oliophyllic properties make it an ideal medium for hydrocarbon filtration. We use only natural cotton fibers (not textile waste) in our products.

Wood absorbs water and acids (extending lube oil drain intervals) and improves the filter’s flow characteristics. Our wood is grown and processed here in locally for excellent cost control.
