The Domnick Hunter K009AA is a precision oil removal filter element for compressed air systems from the British brand Domnick Hunter. It has a filtration accuracy of ≤0.01 μm and a residual oil content of ≤0.01 ppm, classifying it as an AA-grade filter element.
Type: Canister compressed air precision filter element (AA grade, i.e., "ultra-high efficiency oil removal")
Filtration accuracy: ≤0.01 microns, removes oil mist, hydrocarbons, and solid particles.
Typical application: Air compressor after-treatment systems, used in scenarios with high air quality requirements (such as food, pharmaceutical, electronics, pneumatic instruments, etc.)
Corresponding replacement models: Often in the same series as K009AO (1 μm), K009AX (0.01 μm + activated carbon), and K009PF (25 μm pre-filter).
