DL003001 Bowey Stainless Steel Ion Exchange Resin Acid Removal Filter Element
Bowey Ion Exchange Resin Acid Removal Filter Element is a new-generation deep purification element developed for phosphate ester fire-resistant fluid (EH fluid / EHC fluid) systems. Using high-performance spherical ion exchange resin as the core filter material, it relies on stable physicochemical structure and efficient ion exchange reaction to accurately remove acidic substances, metal ions and other harmful components in the oil. It fundamentally inhibits oil degradation, protects servo valves and hydraulic systems, and has been widely used in high-parameter generator sets in electric power, metallurgy, chemical industry and other fields. It has achieved remarkable results in reducing the acid number of fire-resistant fluids, improving oil insulation and flame retardancy, and ensuring safe and stable operation of generator sets.
Core Materials & Working Principle
▶ Core Filter Material: Ion Exchange Resin
Physicochemical properties: strong chemical stability, high temperature resistance, oil immersion resistance, high mechanical strength, long service life. Dual-type resin combination achieves dual purification of acid removal + metal removal:
▶ Weakly basic anion exchange resin
Equipped with permanent basic functional groups, it can quickly neutralize and adsorb phosphoric acid, acidic esters and other substances in the oil, efficiently reduce acid number, and inhibit oil acidification and degradation.
▶ Strongly acidic cation exchange resin
Directionally adsorbs iron, copper, calcium, magnesium and other metal ions in the oil, reduces catalytic oxidation, improves oil insulation resistivity and flame retardant safety performance, and prevents valve corrosion and system failures caused by metal ions.
Working Principle
• Through the dual effects of ion exchange + chemical adsorption during oil circulation:
• Rapidly captures acidic substances and stably controls acid number within qualified range;
• Removes metal ions and polar pollutants to improve resistivity;
• Prevents oxidative decomposition of oil, delays aging and extends oil change interval;
• No secondary pollution, no particle shedding, no phosphate or soap deposits.
Features
▶ All-stainless steel robust structure
The shell and end caps are made of stainless steel, impact-resistant, not easy to deform or break, free of rust and pollution, suitable for long-term operation of high-pressure hydraulic systems.
▶ Industry-leading acid removal capacity, far exceeding traditional media
Acid removal efficiency is significantly better than traditional materials, with strong single-pass acid removal effect, quickly reducing acid number to qualified level.
▶ High-precision resin filter material, no leakage, no particle pollution

▶ Fast acid removal with stable effect
Rapidly reduces acid number, suppresses acid autocatalytic reaction, prevents rapid oil degradation, and significantly extends oil service life.
▶ Significantly improves oil resistivity
Efficiently removes metal ions and polar pollutants, greatly improves insulation performance, reduces electric erosion risk, and protects precision components such as servo valves.
▶ Strong adaptability and easy installation
Can directly replace traditional diatomite and alumina filter elements, compatible with mainstream EH oil filter carts, online purification units and fire-resistant fluid systems.
▶ Long service life & low cost
Large adsorption capacity, low loss, greatly reducing costs for oil changes, downtime maintenance, and valve repair and replacement.
Key Challenges Addressed
Phosphate ester fire-resistant fluid is a special flame-retardant hydraulic medium for high-parameter generator sets and other industrial systems, with excellent lubricity, oxidation resistance and flame retardancy. However, it has obvious shortcomings in actual operation:
• When trace moisture exists in the system, oil is prone to decomposition under high-temperature operation;
• Decomposition starts with the breakage of P-O bonds and C-O bonds, producing strong acidic substances such as phosphoric acid, monoester and diester;
• Acidic substances accelerate oil degradation, forming acid autocatalysis and rapid rise of acid number;
• High-acid oil corrodes precision components such as servo valves, oil pumps and pipelines;
• Precipitation of acidic products and impurities causes servo valve sticking, control failure and unit tripping;
• Declined oil insulation performance and reduced resistivity threaten equipment and production safety.
• Bowey Ion Exchange Resin Acid Removal Filter Element can thoroughly solve the above problems, achieving deep oil purification and long-term system protection.
