E9-44: Main Line Filter (Separation/Coarse Filtration) Function: Used to filter out large amounts of liquid and solid particles larger than 3 microns. Location: Typically installed after the air compressor, before the aftercooler, or at the main line inlet.
E7-44: Air Line Filter (Primary Oil/Water Removal) Function: Filters out liquid water and oil with a filtration accuracy of 1 micron (residual oil content not exceeding 1.0 ppm). Location: Used as pre-cooling protection for refrigerated dryers or as pre-treatment before more advanced filters.
E5-44: High-Efficiency Oil Removal Filter (Micron-Level Coagulation) Function: Coagulates water vapor and oil mist with a filtration accuracy of 0.01 microns (residual oil content not exceeding 0.01 ppm). Location: Commonly used after refrigerated dryers to provide protection for desiccant dryers or precision air-using terminals.
E3-44: Ultra-High Efficiency Oil Removal Filter (Deep Coagulation) Function: Filters out extremely fine solid particles and oil mist with ultra-high efficiency, achieving a filtration accuracy of 0.01 microns (residual oil content not exceeding 0.001 ppm). Location: For high-precision gas environments where oil, water, and dust are strictly prohibited.
E1-44: Activated Carbon Deodorizing Filter (Adsorption Filtration) Function: Primarily adsorbs oil vapor, hydrocarbons, and odors through activated carbon, with residual oil content below 0.003 ppm. Location: Must be installed downstream of an E3 or E5 filter, for use in the food, pharmaceutical, respiratory protection, or electronics industries.
