NMB Technologies F225H High-Performance Centrifugal DC Fan
NMB Technologies F225H High-Performance Centrifugal DC Fan utilizes an aerodynamic impeller design to deliver high pressure and 689CFM maximum airflow. The F225H fan is outfitted with a DC brushless three-phase motor and NMB precision machined ball bearings for a long life expectancy of 70,000 hours. This four-wire fan also features high torque, pulse width modulation (PWM) speed control with a tach signal, efficient motor technology, and low vibration. NMB F225H High-Performance Centrifugal DC Fan operates in an ambient temperature range of -30°C to + 70°C and is ideal for servers, data centers, and telecommunications applications.
