Products Description
The 444973 prioritizes "stable separation" in its core design. It utilizes imported ultra-fine glass fiber composite filter media with a filtration accuracy of 0.1μm, an exhaust oil content of ≤3ppm, and an initial pressure differential of 0.7-1.3MPa. The imported glass fiber layer employs a triple mechanism of inertial impaction, direct interception, and Brownian diffusion to agglomerate oil mist particles into large oil droplets on the fiber surface, which then settle and are recovered. Under standard operating conditions, its service life reaches 3000–4000 hours.
Furthermore, it employs refined roll welding and spot welding processes, along with a two-component adhesive, to ensure long-term structural stability of the filter element. It maintains its shape under pulsating airflow impact and will not collapse due to pressure differential fluctuations. Choosing the 444973 means incorporating the decline in separation efficiency into a predictable maintenance plan, rather than passively responding to sudden "oil spill" incidents.
