Delta Electronics AFL2224HW-00 — 24V DC Brushless Axial Fan, 222mm, 378 CFM, PWM/VSP Speed Control, IP56

The Delta AFL2224HW-00 is a 24VDC brushless axial fan from Delta’s EST (Energy Saving Technology) platform, delivering 378 CFM through a 222mm circular frame at up to 2800 RPM. Its IP56 ingress protection rating, –40 to +60°C operating range, and dual ball bearing construction make it a strong choice for outdoor and tropical environments where moisture, dust, and sustained elevated ambient temperatures are a design constraint. Typical applications include condenser section forced convection, electronics enclosure cooling, heat exchanger air-side management, and outdoor equipment ventilation. Speed is independently controllable via PWM or analog voltage (VSP) on a single shared wire, with open-collector tachometer feedback available for closed-loop speed verification. At 30% PWM duty cycle the fan is capable of a cold start from a full stop, a useful characteristic in intermittently powered systems. |Parameter |Value | |-----------------------------|--------------------------------------| |Manufacturer |Delta Electronics, Inc. | |Model |AFL2224HW-00 | |Fan Type |Brushless DC axial, EST platform | |Rated Voltage |24 VDC | |Operating Voltage Range |21.6 – 26.4 VDC | |Min.
