Product Overview

The HC4704FRT8Z filter element is a precision hydraulic filter accessory designed with SRT special filter material and anti-static innovative structure. It is mainly installed inside the filters of hydraulic stations and lubricating oil stations, used to filter pollutants such as metal debris, gum impurities, dust particles, and sealing debris inside hydraulic oil and fire-resistant oil, continuously control the cleanliness of oil products, and comprehensively protect high-precision components such as servo valves, plunger pumps, and hydraulic cylinders. The product relies on innovative strip shaped anti-static structure design and comes standard with anti-static configuration across all categories. It can effectively eliminate static electricity accumulation caused by high-speed oil flow, avoid hidden dangers such as electrostatic ignition and breakdown of filter materials, and accelerate oil aging and carbonization. With stable filtering performance, it has become a mainstream replacement spare part for equipment maintenance in industries such as thermal power, chemical, and metallurgy.

Product Structure and Technical Advantages

The core of HC4704FRT8Z filter element is processed and formed with SRT special filter material, which has long-term stability and constant filtration accuracy throughout the entire life cycle of the filter element. It will not cause problems such as loose filter layer and accuracy degradation due to media erosion or oil temperature changes. Its filtration performance is better than that of conventional fiberglass filter element under complex alternating working conditions on site, and it can stably control fluid cleanliness indicators for a long time. The product is equipped with an innovative anti-static strip structure, which is the iconic feature of this filter element. The special guide pool structure can guide the static charges generated by oil friction, greatly reducing the accumulation of static electricity inside the oil, effectively avoiding the premature blockage of the filter element caused by electrostatic adsorption of small impurities, and eliminating safety hazards caused by electrostatic discharge. The entire series comes standard with anti-static configuration at the factory, without the need for additional anti-static accessories.

The overall structure of the filter element is compact and small in size, with the characteristics of portability and easy disassembly. It is equipped with a metal support inner skeleton, which has excellent compressive and impact resistance and can adapt to system pressure fluctuations; The end seal is made of oil resistant and corrosion-resistant rubber material, which seals tightly to prevent medium bypass, short circuit and filtration. The folding filter layer layout increases the effective filtration area, provides sufficient pollutant holding capacity, and the pressure difference growth rate is gentle, effectively extending the filter element replacement cycle.

Installation and operation specifications

Before assembling the filter element, clean the oil stains and residual impurities on the filter housing. The overall design is compact and lightweight, and can be disassembled and replaced by a single person, greatly reducing equipment downtime for maintenance. During the daily operation of the equipment, the operation and maintenance personnel rely on the pressure difference value of the filter to determine the blockage status of the filter element. If the pressure difference exceeds the standard, the HC4704FRT8Z new product should be replaced in a timely manner. During the maintenance period of the unit, the filter element should be disassembled and inspected uniformly. If there is any damage to the filter material, aging of the seal, or severe blockage, it should be replaced immediately. Once the filter element fails, impurities and electrostatic hazards increase synchronously, which can easily cause scratches and blockages in precision hydraulic components, accelerate oil deterioration, and increase the probability of equipment failure and maintenance costs.
