The filter element QF1D350CG20HC is a high-precision filter element designed for industrial oil systems. It is mainly used in main engine oil purification devices and is suitable for power plants, ships, metallurgy and heavy machinery. The filter element intercepts particulate pollutants (such as metal debris, colloids, etc.) in the oil to ensure the cleanliness of the lubrication system and hydraulic equipment, thereby extending the service life of key equipment and improving operational stability.

Technical parameters

- Filter material structure: The filter element QF1D350CG20HC adopts multi-layer composite glass fiber filter material, with stainless steel support mesh, which has high dirt holding capacity and mechanical strength

- Pressure resistance: The maximum working pressure reaches 32MPa, suitable for high-pressure oil circuit environment

- Temperature resistance range: -30℃ to 150℃, suitable for wide temperature range working conditions

- Certification standard: Meets ISO 2943 (structural integrity) and ISO 4572 (multiple pass tests) industry specifications

Core performance advantages

1. High pressure tolerance: The optimized skeleton and filter material structure can stably withstand high pressure impact and avoid deformation or damage of the filter element caused by pressure fluctuations.

2. Accurate interception ability: Adopting gradient density filtration technology, it intercepts pollutants of different particle sizes layer by layer, effectively protecting high-precision components such as servo valves and oil pumps.

3. Long life design: Through the combination of enhanced glass fiber filter material and galvanized perforated plate skeleton, the dust holding capacity is significantly improved, the replacement frequency is reduced, and the maintenance cost is reduced.

4. Compatibility and replaceability: Supports replacement of original filter elements, providing a more cost-effective solution while ensuring the same filtering performance.

Typical application scenarios

- Power industry: turbine fire-resistant oil system, EH oil station return oil pipeline and servo valve front end protection

- Industrial lubrication system: thin oil station, gearbox lubricating oil circulation purification

- Heavy machinery: hydraulic transmission system, engineering machinery power unit oil filtration

Maintenance and replacement recommendations

- Periodic monitoring: It is recommended to check the filter element pressure difference every 6 months of operation or after 3000 cumulative working hours. If the pressure difference exceeds 0.35MPa, it needs to be replaced immediately.

- Synchronous maintenance: When replacing the filter element, the oil tank and pipeline must be cleaned simultaneously to prevent residual pollutants from causing secondary pollution.

- Adaptability confirmation: Before installation, the system pressure, flow and interface size must be checked to ensure compatibility with the equipment.

The filter element QF1D350CG20HC has become the preferred solution in the field of industrial oil purification due to its high-precision filtering performance, excellent adaptability to working conditions and economy. Through strict quality control processes and customized services, this product can meet the dual needs of users in different industries for oil cleanliness and equipment reliability, helping enterprises achieve cost reduction, efficiency improvement and safe production goals.
