Hydraulic Fiberglass Inline Oil Filter Element The hydraulic filter element is used in the hydraulic system to filter out particulate debris and rubber impurities to ensure the cleanliness of the hydraulic system. In order to reduce the dimensions of the filter element and increase the filtration area, the filter layer is generally folded into a corrugated shape, and the layer is generally pleated below 20 mm. The inside skeleton is professional rust-proof and tested by salt spray testing stand to extend the storage life effectively. The pleated filter layer has an outside skeleton which protects the filter layer and distributes the incoming fluid over the filter layer evenly. Also the outside skeleton can protect the filter layer away from mechanical damage. Filtration rating: BN/HC: 3-20 µm Size: 0030, 0035, 0055, 0060, 0075, 0095, 0110, 0140, 0160, 0240, 0260,0280, 0300, 0330, 0450, 0500, 0650, 0660,0900, 0990, 1320, 1…
