Differences Between Single Filter Element and Three Filter Elements for PO Series Portable Oil Purifier
Filtration Effect & Precision
Single filter element: Only one-stage filtration, can only remove larger particles and impurities from oil, with relatively low filtration precision.
Three filter elements: Adopt three-stage progressive filtration, can intercept impurities layer by layer from coarse to fine, achieve higher cleanliness, and remove 3-5μm fine particles more effectively.
Contamination Holding Capacity & Service Life
Single filter element: Small contamination holding capacity, easy to reach pressure alarm and need frequent replacement/cleaning.
Three filter elements: Larger total contamination holding capacity, longer service life, reduce replacement frequency and lower maintenance workload.
Pressure & Operation Stability
Single filter element: Pressure rises faster when handling heavily contaminated oil, may affect normal operation.
Three filter elements: More reasonable pressure distribution, slower pressure rise, more stable working condition, suitable for long-time continuous filtering.
Application Scope
Single filter element: Only for lightly contaminated oil and simple oil transfer/filtration.
Three filter elements: For severely contaminated oil (insulating oil, turbine oil, lubricating oil), and can be used as bypass filtration for hydraulic/lubrication systems.
Cost & Usage
Single filter element: Lower initial purchase cost, suitable for temporary and simple working conditions.
Three filter elements: Higher cost but more cost-effective for long-term and heavy-duty use, with better oil purification quality.
