When selecting and evaluating wound filter cartridges, the following core parameters shall be considered:
Parameter Category | Detailed Parameters | Description |
Filtration Rating | 1μm, 5μm, 10μm, 20μm, 50μm, 100μm, etc. | Refers to the minimum particle diameter that can be effectively trapped. It is one of the most important selection parameters. |
Filter Media | PP (Polypropylene): General-purpose, acid and alkali resistant, low cost.Absorbent Cotton: Suitable for aqueous solutions with good hydrophilicity.Glass Fiber: High temperature resistant, high precision, commonly used for special solvents or high-temperature environments.Polyester: Better solvent resistance than PP. | The material determines the chemical compatibility and application scope of the filter cartridge. |
Core/Support Rod | PP, Stainless Steel (e.g. 304, 316L) | Supports the filter cartridge structure and ensures pressure resistance. Stainless steel core offers stronger corrosion resistance. |
Dimensions | Outer Diameter: ∅63mm, ∅115mm, etc.Length: 10 inch (254mm), 20 inch (508mm), 30 inch (762mm), 40 inch (1016mm) | Must be compatible with the filter housing. |
Operating Pressure Differential | Normally 0.1 – 0.4 MPa | Maximum allowable pressure difference between inlet and outlet. Exceeding this value may damage the cartridge structure. |
Operating Temperature | PP: ≤ 60℃Absorbent Cotton: ≤ 120℃Glass Fiber: ≤ 150℃ or higher | Depends on the filter yarn material, affecting long-term stability and service life. |
Dirt-Holding Capacity | High | The depth filtration structure enables high dirt-holding capacity, extending replacement intervals. |
Yarn filter cartridges are an economical, efficient and reliable depth filtration solution, especially suitable for pre-filtration and protective filtration with high flow rate and high impurity content.
