Recently, the EPSEA line filter has achieved SGS certification, verifying its compliance with international standards. In terms of the filtration performance for suspended oil and solid particles, it has surpassed the Class 1 standard specified in ISO8573-1. This accomplishment represents a significant breakthrough achieved by EPSEA as a result of its continuous endeavors in the field of filtration technology.
The test sample is 1.5 m³/min compressed air line filter (EP-001G) of EPSEA, which adopts a four stage series testing method to better simulate real-world application scenarios.
Test Standard: ISO 12500-1:2007 Filters for compressed air—Part 1：Oil aerosols
Test Conditions and Results：
Comparison of test results with ISO8573-1 standard
Suspended oil test result.
The oil concentration within the compressed air has been cut down from 10.2mg/m³ to 0.0001mg/m³ through filtration. (According to ISO8573 - 1, the oil content for Class 1 should be ≤0.01mg/m³) The achieved filtration efficiency exceeds 99.99%, thus not only meeting but surpassing the oil content standard of Class 1 in ISO8573-1.
Test Standard: ISO 12500-3:2009 Filters for compressed air—Test methods—Part 3: Solid Particles
Test Conditions and Results：
Comparison of test results with ISO8573-1 standard
In the solid particle test, before filtering 49L of compressed air, the cumulative count of 0.1-0.5μm solid particles reached 1,203,664. After filtration, this number dropped to 323. Calculated per cubic meter of compressed air, there are 6592 particles of this size range. (below the ISO8573-1 Class 1 requirement of ≤20000 particles per cubic meter) For 0.5-1μm solid particles, there were 7 particles in the filtered sample, equivalent to 143 particles per cubic meter of compressed air. (less than the ISO8573-1 Class 1 limit of ≤400 particles per cubic meter) Regarding 1-5μm solid particles, none were detected, corresponding to 0 particles per cubic meter. (below the ISO8573-1 Class 1 standard of ≤10 particles per cubic meter) Evidently, the test results demonstrate that the filtration performance has not only met but exceeded the ISO8573-1 Class 1 solid particle standard.
Furthermore, the total differential pressure across the four filters in this test stood at 0.0335MPa. This figure clearly illustrates that EPSEA filters not only deliver exceptional filtration performance—effectively removing solid particles of varying sizes—but also keep pressure drop within a reasonable range. They not only meet high filtration standards but also ensure optimal pressure drop performance during system operation, truly embodying the product's outstanding design and manufacturing prowess in balancing performance and energy efficiency.
EPSEA's line filter has achieved internationally leading performance, ensuring reliable clean compressed air for industrial applications.Through continuous innovation in core filtration technology, smart manufacturing, strict quality control, and comprehensive services, EPSEA drives excellence in every breakthrough, delivering superior filter performance.
