精密过滤器经过三层过滤，第一层是滤芯的表面层，滤去可见的大粒子；第二层是上层，滤去较小的粒子；第三层是加压层，滤去微米级的粒子。所以华日自主生产3r精密过滤器能保证油液达到NAS7-8级，甚至达到NAS5~6级。金硕自主生产3r精密过滤器设备轻小，技术安全性高，体积小，设备安装简单、而且成本相对低。维护容易，只需定期更换滤芯3R精密滤油机：        CS-SS305-2RBQ,CS-SS102-1RB,CS-SS103-2RB,CS-SS103-3RB,CS-SS304-2RB,CS-SS304-1RB,CS-SS305-1RB,CS-SS305-2RB,CS-SS103PF-10-20-1RB,CS-SS104PF-10-20-1RB,CS-SS104PF-10-20-2RB,CS-SS104PF-10-20-3RB,CS-SS312PF-20-20-1RB,CS-SS312PF-20-20-2RB,CS-SS103-4PF10-20-1RB,CS-SS103-4PF10-20-2RB,CS-SS305-12PF20-20-1RB
