Ultrafilter FF04/20 is a mid-range oil-removing precision filter element from the German ULTRAFILTER FF series, designed fit 04/20 specification filter housings. As an advanced purification component following PE04/20 pre-filtration, it handles a higher flow rate than FF04/10 model in the same series. Core Performance Parameters Filtration Precision: Utilizing a multi-layer glass fiber composite filter media with a0.01μm rating, it efficiently removes oil mist, fine particles, and condensate from compressed air. The residual oil mist content after filtration is as as 0.01mg/m³ (i.e., 0.01PPM), with a filtration efficiency of 99.9%, meeting the ISO8573-1 Class 1 standard requirements. It provides effective protection for downstream high-precision filtration elements. Structural Design: It features combined structure of an aluminum alloy end cap, a 304 stainless steel skeleton, and an outer hydrophobic foam sleeve. Pre-installed O-rings prevent airflow-circuiting, and an optimized pleating process maximizes the filtration area. With an initial differential pressure of ≤0.02MPa, it offers low differential pressure and energy consumption. Under normal operating conditions, its service life is approximately 8,000 hours, requiring complete replacement after reaching its service cycle, as it non-regenerable. Applicable Conditions: The rated flow rate is 2.0 Nm³/min, which is 1.33 times that of FF04/10 (1.5 Nm³/min), making it suitable for medium-to-large flow compressed air purification systems. The operating pressure range 0.8-1.6MPa, and the operating temperature covers -10°C to 80°C
