HEPA Filter Media
High-efficiency particulate air (HEPA), also known as high-efficiency particulate absorbing and high-efficiency particulate arrestance, is an efficiency standard of air filer.
Description
High-efficiency particulate air (HEPA), also known as high-efficiency particulate absorbing and high-efficiency particulate arrestance, is an efficiency standard of air filer. Filters meeting the HEPA standard must satisfy certain levels of efficiency. Common standards require that a HEPA air filter must remove—from the air that passes through—at least 99.95% (European Standard) or 99.97% (ASME, U.S. DOE) of particles whose diameter is greater than or equal to 0.3 um. Srilan offer two types of HEPA filter media. Melt blown which can be laminated with carrier materials for HEPA filter. Composite Materials which can be directly pleated for HEPA filter. Srilan has mastered the melt blown electrostatic charging core technology, and can keep upgrading performance.
