SP-030-E-10-B/4 STAUFF Oil filter element uses high-quality fiberglass filter material, which is widely used in hydraulic systems to filter out solid particles and gel like substances in the medium, reduce the relative surface friction of hydraulic components, improve system reliability, and ensure the safe and efficient operation of hydraulic and lubrication systems. Our company has been focusing on the localization and replacement of filter cartridges for a long time. Based on some technical parameters provided by customers, we can produce filter cartridges that meet the performance requirements of the original filter cartridges, ensuring the cleanliness of the system. We are completely trustworthy.

Q: What are the materials of filter cartridges? What are the corresponding precision ranges?

Answer: According to the classification of filter materials, there are: oil filter paper: 10-50um, glass fiber: 1-70um, HV glass fiber: 3-40um, metal mesh: 3-500um, sintered felt: 5-70um, wire gap filter: 15-200um.

Q: What brands of filter cartridges do you make?

Answer: Our factory produces alternative universal filters for foreign brands such as Pall, Hedeke, Dasheng, Parker, and Rexroth, as well as national standard oil suction filters, return oil filters, high-pressure filters, and coalescence dehydration filters. We support non-standard customization and welcome samples or drawings for processing and customization.

Q: How do customers choose the appropriate filter size when making their own filters?

Answer: We need to provide the flow rate, pressure, external dimensions, accuracy, filtering medium and other parameters of the filter designed by the customer. We will provide the customer with the selected filter element size and quantity based on the filter size.

Q: Is there any difference between filtering kerosene, gasoline, diesel filters and general hydraulic oil filters?

Answer: The sealing material used for the filter element is different. Generally, nitrile rubber is sufficient for the sealing ring of hydraulic oil filter elements, while fluororubber rings are required for filtering media such as kerosene, gasoline, and diesel.

Q: Can a regular oil filter be used to filter cutting fluid?

Answer: Cutting fluid is made by blending cutting fluid oil with water, and plays a role in lubrication, cooling, cleaning, rust prevention, etc. during the cutting process. The main impurities in the used cutting fluid are metal shavings and powder. The filter element and filter material used for this medium are generally made of 304 stainless steel, and the end cap skeleton of the filter element is made of carbon steel material, which requires special BH treatment.

Q: How effective is our filter cartridge?

Answer: Our filter cartridge uses two types of filter materials to choose from: domestic South Glass Fiberglass and imported HV Fiberglass. Both of these filter material brands are high-quality domestic and foreign brands, with stable performance, high filtration accuracy, large pollutant absorption capacity, and better filtration effect. There is a strict inspection process at the factory to ensure that every filter element is of high quality.
