Ultrafilter PE03/05 is a pre-filtration grade compressed air precision filter element from the German ULTRAFILTER PE series compatible with 03/05 specification filter housings. It serves as the first-stage coarse filtration component in the air source purification system, with a higher positioning the PE02/05 models in the same series. Core Performance Parameters Filtration Precision: It belongs to the 3μm pre-filtration, which can efficiently filter out solid particles, condensate, and large oil mists in compressed air. The residual oil content after filtration is ≤0.5P, providing protection for downstream fine filtration grade filter elements such as FF/MF/SMF. Structural Design: It adopts imported European fiberglass filter media paired with a steel frame, and the outermost layer is equipped with an oil-resistant and acid-resistant hydrophobic foam sleeve to prevent coalesced liquids from re-entering the airflow. overall unit features corrosion resistance, low airflow resistance, and high strength. Applicable Working Conditions: The rated processing flow rate is 0.4 Nm³/, which is 2.5 times that of the PE02/05 (0.16 Nm³/min). The conventional service life is approximately ,000 hours, and it must be replaced entirely after reaching its service cycle, as it is not regenerable
