Ultrafilter FF03/05 is a mid-range oil-removing precision filter element from the German ULTRAFILTER FF series compatible with 03/05 specification filter housings. It serves as an advanced purification component after PE03/05 pre-filtration, with a higher flow rate than the FF02/05 models in the same series. Core Performance Parameters Filtration Precision: Utilizing 0.01μm grade composite filter media, it can efficiently filter out oil mist, microparticles, and condensate from compressed air. The residual oil mist content after filtration is as low as .01PPM, with a filtration efficiency of 99.99%, providing effective protection for downstream high-precision filtration elements. Structural Design: It a combined structure of aluminum alloy end caps, a stainless steel skeleton, and an outer hydrophobic foam sleeve, pre-installed with O-ring seals. The overall unit is characterized by corrosion resistance, low airflow resistance, and difficulty in secondary carrying of coalesced liquids. It has a service life of approximately 8,000 and must be replaced entirely after reaching its service cycle; it is non-renewable. Applicable Working Conditions: The rated processing flow rate is 0.4³/min, which is 2.5 times that of the FF02/05 (0.16 Nm³/min), making it suitable for mediumflow compressed air purification systems. The operating pressure range is 0.8-1.6MPa
