The raw materials and technical specifications of direct-return oil return filters vary according to different models and brands. However, generally speaking, their primary raw materials encompass filtration media (such as glass fiber, stainless steel mesh, etc.) and housing materials (like aluminum alloy, stainless steel, etc.). Below are some typical technical specifications of direct-return oil return filters for your reference:
I. Raw Materials
Filtration Media:
Glass Fiber: Commonly used in micro-sized direct-return oil return filters due to its excellent filtration efficiency and high filtration precision.
Stainless Steel Mesh: May be employed in certain high-end or special applications as filtration media to enhance the filter's corrosion resistance and strength.
II. Technical Specifications
Please note that the following are common technical specifications for direct-return oil return filters, but these parameters may vary depending on the product model and brand:
| Technical Specification | Typical Value/Range |
|---|---|
| Filtration Precision | 1-30μm |
| Nominal Flow Rate | 25-1300L/min |
| Nominal Pressure | 1.6MPa |
| Operating Temperature | -30℃~110℃ |
| Filtration Media | General hydraulic oil, phosphate ester hydraulic oil, emulsion, water-glycol, etc. |
| Outlet Connection Type | Threaded connection, flange connection, etc. |
| Other Features | Easy installation and connection, simplifying system piping; filter element replacement without system shutdown (double-cartridge type); equipped with transmitters (in some models), etc. |
Please note that the above technical specifications are provided as examples and do not necessarily represent the specific parameters of all direct-return oil return filters. When selecting a direct-return oil return filter, it is essential to consider the actual application requirements, working environment, and specific equipment needs. Additionally, it is recommended to refer to the product manual or consult professionals for more accurate information.
