ebm-papst 4314 Series Compact DC Axial Fans With Speed Alarm and Optional NTC Temperature Sensor

What is a DC axial fan

An axial fan is a device that creates airflow by using a motor to rotate blades housed within in a square or round frame. The rotating fan blades draw air into the fan and expel the flow in the same direction across a surface to cool it. Axial fans are a vital component ensuring the smooth operation of machinery and electronic equipment. Keeping equipment cool is Crucial as overheating can lead to serious complications including premature deterioration of parts, shorter life spans and sometimes, complete failure.

Ebm-papst 4314 Series Compact DC Axial Fans with Speed Alarm and optional NTC temperature sensor

From ebm-papst, the 4314 series of high performance ball bearing fans with a speed alarm output. Offering a cost effective cooling solution without sacrificing on quality or reliability. The compact DC axial fans are expertly designed supporting excellent efficiency long service life and smooth operation. With a robustly constructed PBT housing and PA impeller, the 4314 series fans are an ideal for multitude of cooling applications. An optional NTC (negative temperature Coefficient) resistor is available separately, see part number 826-1382

Alarm Signal

Alarm signals are used when the speed of a fan must be monitored. When a fault occurs, an alarm is raised. Axial fans with an alarm feature produce a continuous high signal via and open collector when operating within its normal set parameters. When a fault occurs and the fans speed alters from its original set point a low signal is emitted, triggering an alarm. Once the fault has been corrected the fan returns to the set point speed.

Key features and Benefits
