The key technical advantages of DAYEAR’s filtration fabric include uniformity of thickness, weight and flow resistance, with no vulnerable thin spots. Others are the filtration efficiency, the rigidity of the pleats against deflection, the high mass and consequent high surface area and strength of the material, the fine diameter of the fibers, and the trilobal fiber shape which adds further to the surface area for particle adsorption.(Note: all the manufacturers' name and brands' name are just for reference purposes only, we own an independent brand. ) ProductSiteLaunchDate : 2023-07-21T09:23:18.726Z Size : 425 Sq.
