Since its establishment, it has been consistently focusing on the research and development and innovation of hydraulic systems and related fluid technologies. Through years of in-depth cultivation, it has established a good brand image worldwide.

Its filter products are rich and diverse, forming a complete product line. It includes hydraulic filters suitable for various hydraulic systems, which can effectively filter impurities in hydraulic oil and ensure the high-precision operation of hydraulic systems; lubrication filters for lubrication systems that can remove harmful particles in lubricating oil and extend the service life of equipment's lubricated parts; fuel filters used for fuel filtration to ensure the cleanliness of fuel, enabling power equipment such as engines to burn more fully and operate more stably; and air filters that perform excellently in air filtration, creating a clean intake environment for equipment and reducing damage to equipment caused by dust and other pollutants.

These filters are made of high-quality raw materials, such as advanced synthetic fiber materials, stainless steel filter meshes, and specially treated filter papers. Different materials are scientifically combined according to the specific uses and application scenarios of the products, enabling STAUFF filters to exhibit outstanding performance in terms of filtration accuracy, dirt-holding capacity, pressure resistance, and corrosion resistance.

ANALYSIS OF THE CORE WORKING PRINCIPLE

The working principle of STAUFF filters is a multi-dimensional and multi-level sophisticated process, integrating multiple mechanisms such as mechanical interception, deep adsorption, and physicochemical synergy to jointly achieve efficient purification of fluids.

Mechanical Interception

This is the most intuitive and fundamental filtration method. When the fluid enters the filter, the filter medium with a specific pore structure inside the filter begins to play its role. For example, in a hydraulic filter, solid particles larger than the pore size, such as metal chips, sand grains, and other mechanical impurities, will be directly intercepted by the outer filter mesh structure of the filter. It's like a fine sieve that blocks large particle impurities on the surface of the filter, preventing them from entering the subsequent equipment system along with the fluid and avoiding wear, scratches, and other damages to precision components such as hydraulic pumps and valves, thus building the first line of defense for the stable operation of the equipment.

Deep Adsorption

Based on mechanical interception, the deep adsorption mechanism further enhances the filtration effect. Some special materials inside the filter possess powerful adsorption properties, enabling them to capture smaller particles, colloidal substances, and some dissolved impurities in the fluid. For example, some filters made of modified fibers have active groups on the fiber surface. These groups can have physical or chemical adsorption effects on tiny pollutants in the fluid. Oxides and colloidal components in the oil, for example, will be firmly adsorbed inside the filter, achieving in-depth purification of the fluid and enabling the fluid to meet higher purity standards and meet the strict requirements of equipment for clean media.

Physicochemical Synergy

Even more ingeniously, during the entire filtration process, there is also a physicochemical synergy. When some filter materials come into contact with impurities in the fluid, they can change the properties of the impurities through chemical reactions, making them easier to be adsorbed or precipitated. For example, for fluids containing certain metal ions, some components in the filter can undergo complexation reactions with them, converting free metal ions into stable complexes, which are then fixed on the filter through adsorption. This complementary combination of physical and chemical effects enables STAUFF filters to exhibit excellent purification capabilities when dealing with fluids with complex compositions.

KEY CONSIDERATIONS FOR PRECISE FILTER SELECTION

Matching Filtration Accuracy

Different industrial equipment and production processes have vastly different requirements for the cleanliness of fluids. In hydraulic systems in fields such as aerospace and high-end precision machining, to ensure the normal operation of extremely precise components and prevent damage caused by even micron-sized tiny particles, filters with a filtration accuracy of 1 - 3 microns or even higher are often required. In some industrial scenarios where the requirements for fluid cleanliness are relatively less stringent, such as ordinary industrial water filtration or general mechanical equipment lubrication systems, a filtration accuracy of around 10 - 20 microns may be sufficient to meet the needs. STAUFF filters fully consider this diverse market demand and offer a variety of products with different filtration accuracies ranging from 0.5 microns to 100 microns, facilitating customers to make precise matches according to the actual requirements of their equipment.

Matching Flow Rate and Pressure

The flow rate of the equipment and its working pressure are essential factors that must be carefully considered when selecting filters. For industrial systems with large flow rates, if the flow-through capacity of the filter is insufficient, it is prone to clogging, which will lead to a sharp decline in flow rate and excessive pressure loss in the system. Therefore, it is necessary to choose a filter that can adapt to large flow rates to ensure smooth fluid passage. Moreover, the pressure resistance of the selected filter must match the working pressure of the system. For example, in high-pressure petrochemical pipeline systems or large hydraulic stamping equipment, only by selecting STAUFF filters with high-pressure resistance grades can stable and reliable operation be ensured in a high-pressure environment, preventing safety hazards such as rupture and leakage due to the inability of the filter to withstand high pressure and ensuring the safety and normal operation of the entire system.

Considering the Characteristics of the Working Medium

Since different working media have different chemical and physical properties, it is required that the filter material be perfectly compatible with them. For example, when dealing with media containing corrosive chemicals, such as fluids with strong acidity or alkalinity encountered in some chemical production processes, it is necessary to choose STAUFF filters with excellent corrosion resistance. Such filters are usually made of materials with special coatings or are inherently corrosion-resistant. When filtering high-viscosity lubricating oils, considering the poor fluidity of the fluid, filters with appropriate pore structures and those that can adapt to the passage of high-viscosity fluids in terms of structure and material should be selected to ensure good filtration performance and avoid affecting the lubrication and normal operation of the equipment due to poor filtration.

Meeting Special Functional Requirements

Nowadays, many equipment have various special functional requirements for filters. If the equipment needs to monitor the pollution level of the filter in real time to facilitate timely replacement, STAUFF filters with pollution indication devices can be selected. These filters can provide intuitive signal prompts to let operators clearly know the working status of the filter. In addition, for equipment operating in harsh environments such as high temperature, low temperature, or high humidity, it is necessary to choose filters with corresponding protective properties, such as high-temperature-resistant, low-temperature-resistant, or moisture-proof STAUFF filters, to ensure that the filters can still play a stable filtering role in special environments and maintain the normal operation of the equipment.
