24V Fans
QwikFlow 24VDC Fans are available in a full range of sizes. These dc fans are used in different applications where a higher voltage can be used allowing for a lower current may be needed. 24vdc fan applications can be found in industrial applications and the telecommunications industry. These dc fans are also available with options such as tachometer, locked rotor alarm, thermo control and PWM. These dc fans are impedance protected and also reverse polarity protected.
QwikFlow 24V Fan series have motor protection such as Impedance protection and Reverse Polarity protection. QwikFlow DC Fans also have options available such as Auto-Restart, Thermal Speed Control, Tachometer Speed Sensor, Locked Rotor Alarm and PWM (Pulse Width Modulation). QwikFlow DC Fan series also can be IP Rated for dust proofing and water resistant DC Fan.
