Ultrafilter SMF04/20 is a super oil-removal fine compressed air filter element from the German ULTRAFILTERF series, designed for 04/20 specification filter housings. It serves as the fourth-stage ultimate purification component following PE04/20 prefiltration, FF04/20 medium-stage oil removal, and MF04/20 high-precision oil removal, with a higher processing flow rate the SMF04/10 model in the same series. Core Performance Parameters Filtration Precision: Utilizing 0.01μm grade nanomicrofiber composite filter media, it efficiently removes oil mist, microparticles, condensate, and odor molecules from compressed air. The residual oil mist content after filtration is as as 0.01PPM, with a 100% removal rate for particles of 0.01μm and above, making it of the highest oil-removal precision levels in the ultrafiltration filter element series. Structural Design: It features a combined structure of a 304 stainless steel frame an outer hydrophobic foam sleeve. The optimized pleating process increases the filtration surface area by 450% compared to traditional filter elements, offering higher dirt-holding and an initial differential pressure of ≤0.02MPa. This can reduce compressed air system energy consumption by up to 70%. Under normal operating conditions it has a service life of approximately 8,000 hours and must be replaced entirely after reaching its service cycle, as it is non-regenerable. able Conditions: The rated processing flow rate is 2.0 Nm³/min, which is 1.33 times that of the SMF04/0 (1.5 Nm³/min), making it suitable for medium-to-large flow compressed air purification systems. The operating pressure range is 0.81.6MPa, and the operating temperature covers -10°C to 80°C.
