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.
