Separation Filter (Grade E)

· Designed to remove bulk liquid and 3‑micron coalesced contaminants; residual oil content up to 5 ppm.

Main‑line Filter (Grade D)

· Replaces conventional ceramic filter elements with multi‑layer glass‑fiber media. · Main‑line filter: typically used as pre‑filtration for reciprocating air compressors. · Removes bulk oil and water aerosol from compressed air down to ≤ 1 ppm; solid particulate removal down to 1 micron.

High‑efficiency Oil‑removal Filter (Grade C)

· Constructed of stacked multi‑layer glass‑fiber media. · Air‑line filter: this grade serves as pre‑filtration for general‑purpose pipelines and standard screw air compressors. · Filters oil, water aerosol and liquid in compressed air down to ≤ 0.01 ppm; solid particulate removal down to 0.01 micron.

Ultra‑high‑efficiency Oil‑removal Filter (Grade B)

· Glass‑fiber media consisting of membrane‑sealed mesh sleeves and multi‑tube matrix blended‑fiber media. · Ultra‑precision oil‑removal filter: post‑filtration unit for compressed‑air systems. · Suitable for removing trace‑level oil and water aerosol from compressed air; precision filtration down to 0.001 micron to deliver high‑quality oil‑free compressed air.

Ultra‑precision Activated‑carbon Filter (Grade A)

· Made of fine activated‑carbon powder combined with multi‑layer fiber media. · Dedicated for high‑precision filtration applications. · Removes residual oil mist in compressed air down to ≤ 0.003 ppm, eliminates hydrocarbon odors, and captures ultra‑fine particulates down to 0.01 micron, achieving optimal oil‑free and odor‑free performance.
