Delta Electronics QFR DC Axial Fans

Delta Electronics QFR DC Axial Fans are engineered for low noise and low power consumption and include a tach/PWM option. These fans use a power-saving circuitry design to create low acoustic switching noise. Delta Electronics QFR DC Axial Fans deliver greater performance when placed on the intake with an air filter compared to other fans of the same form factor. This performance makes the QFR series ideal for quiet office environments.
