Recently, The EPSEA precision line filter has achieved SGS certification, verifying its compliance with international standards, achieving breakthroughs in suspended oil and particulate filtration. Test results show that in the suspended oil test, compressed air oil concentration dropped from 10.2 mg/m³ to 0.0001 mg/m³ with over 99.99% filtration efficiency, meeting Compressed air—Part 1 Contaminants and purity classes Class 0 oil content level. In the particle test, filtration efficiency across all particle sizes met Class 0 particle level in the standard.
The test sample is 1.5 m³/min compressed air precision 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：
Test Standard: ISO 12500-3:2009 Filters for compressed air—Test methods—Part 3：Particulates
Test Conditions and Results：
This achievement not only demonstrates that EPSEA's precision line filter has reached international leading filtration performance but also ensures reliable support for industries relying on clean compressed air.
EPSEA's continuous focus on core technology and quality control spans material R&D, intelligent manufacturing upgrades, rigorous end-to-end quality assurance，and relentless exploration by its top R&D team. Every innovation from material selection to R&D breakthroughs reflects its commitment to excellence, driving the filter's superior performance.
The high quality of EPSEA line filter elements stems from its rigorous production process. Starting from the winding of the filter layer, production personnel strictly follow the drawing specifications to ensure that the filter material is wound tightly without deformation or looseness, eliminating problems such as filter layer damage and winding deviation.
During the installation of the outer skeleton, fine operations are adopted to avoid scratching the filter layer, and the filter material is precisely trimmed to ensure it is flush with the edge of the skeleton. In the assembly link, steps such as sponge sleeve installation, end cover cleaning, and adhesive application all follow strict standards to ensure the tightness and integrity of the components.
After the adhesive curing process for 4-6 hours at room temperature, the product also needs to undergo multi-dimensional inspections such as dimensional accuracy and geometric tolerance. After completing the installation of components, it is finally tested according to strict factory inspection technical conditions, and qualified products can be packaged and stored.
This SGS certification authoritatively recognizes EPSEA's product quality and embodies its commitment to sustained innovation and excellence in compressed air purification. In the future, EPSEA will deepen technological R&D, leveraging high-standard products and services to drive industry growth, enabling more efficient, cleaner production environments, and continuously leading the compressed air purification industry to new heights.
