The Hiross 240Q is a Q-class (precision filtration) filter element in Hiross compressed air systems from the Italian brand Hiross. It has a nominal diameter of 240mm, is suitable for operating pressures of 0.7MPa (maximum approximately 1.0MPa), and typically has a filtration accuracy of 5 microns. The material is mostly glass fiber, used to remove oil, water, and solid particles from compressed air.
240 indicates the filter element size/diameter, and Q stands for "Quantitative" class (precision filtration, accuracy ~5μm). Other filters in the same series include P (1μm), S (0.01μm, oil mist removal), and C (0.01μm + activated carbon, oil vapor removal).
It is used in air compressor post-treatment lines, before and after refrigerated or desiccant dryers, for pre-filtration or final precision filtration.
