PH-F140XP's nine blades with MVB feature produce powerful yet silent downdraft airflow. With the UFB bearing, composed by MOSS and SSC systems, long lifespan and rotation stability are made possible.
The new nine high pressure MVB blades are precisely angled to generate a silent controlled airflow. The blades produces a downdraft vortex allowing for greater amount of air passage through and reduce airflow turbulence across the surface of the blades to create significantly better performance and airflow while keeping noise to a minimum.
The new redeveloped blades in PH-F140SP are angled lower to achieve higher air pressure. The redesigned MVB blades generate better airflow and produces better performance. It improves the balance of airflow and air pressure when using with as a case fan.
