The PH-F200SP, a high static pressure fan, have the ability to overcome the airflow restriction caused by high fin density.. Air flow - 110.1 CFM. Noise level - 25.0 decibels The PH-F200SP has a larger base size with a magnetic brushless DC motor to avoid the effects of resonance and for rotational stability. To create better structural strength, redesigned the back frame of the PH-F200SP. With the noise reduction challenges in mind, we modified the component for lower actuator noise, PCBA for lower electromagnetic noise, brushless motor structure for lower operating noise and frame rib for lower wind and vibration noise. The nine high static pressure MVB blades are precisely angled to generate a focused controlled airflow. The blades produces a downdraft allowing for greater amount of air passage through and reduce airflow turbulence across the of the blades Eight pre-installed rubber pads are now bigger and designed to reduce more vibration. Composed by MOSS and systems, ' UFB bearings have an effective hub-tip ratio to achieve a state of equilibrium reducing air and vibration noise. provides an increase in the bearing's lifespan and ensures that the fan's is consistently operational and quiet.
