The Hiross 180S is an S-class filter element from the Italian brand Hiross, designed for compressed air precision filters. It has a flow rate of 180 Nm³/min, a filtration accuracy of 0.01 μm, and residual oil content ≤ 0.01 ppm (w/w). It is used to efficiently remove liquid water, oil mist, and solid particles ≥0.01 μm from compressed air.
180 indicates the rated flow rate of 180 Nm³/min, and S represents S-class (high-efficiency precision filtration, non-activated carbon).
The filtration accuracy is 0.01 μm, and the residual oil content is ≤0.01 mg/m³ (≈0.01 ppm), making it suitable for applications with stringent air quality requirements, such as spraying, pharmaceuticals, and electronics.
It typically contains a stainless steel frame and borosilicate fiber filter media, with a pressure resistance of approximately 1.6–2.1 MPa (depending on the specific housing). The recommended replacement interval is 8000 hours.
