Delta Cooling Fan THB1748BG – High-Performance 172mm Industrial Axial Fan
The Delta Cooling Fan THB1748BG is a premium, industrial-grade thermal management solution engineered to deliver massive airflow and high static pressure for the most demanding cooling applications. Designed by Delta Electronics, this high-velocity axial fan is built to operate under extreme thermal loads. With its round 172mm diameter and thick 51mm profile, it is optimized to push air through high-density components, making it a critical asset for server racks, telecommunication systems, and heavy-duty power inverters.
Operating on a standard 48V DC power supply, the Delta Cooling Fan THB1748BG consumes up to 168 Watts of power (reaching up to 201.6 Watts under peak conditions) to drive its rugged impeller. It features a robust die-cast aluminum frame paired with an industrial-grade plastic blade system, offering the perfect combination of structural strength and aerodynamic efficiency. For applications that cannot compromise on system cooling, this dual ball-bearing fan delivers high reliability over a long service life.
Key Features of Delta Cooling Fan THB1748BG
-
Colossal 607 CFM Airflow: Generates an outstanding 607.07 CFM (17.17m 3min) of volumetric air movement to rapidly flush out hot air from high-density enclosures.
-
High Static Pressure Output: Delivers a maximum static pressure of 4.136 in H_2 O (105.5 mmH_2 O), enabling it to push air through thick dust filters and dense internal heatsinks.
-
Intelligent PWM Speed Control: Outfitted with a dedicated Pulse Width Modulation (PWM) input wire, allowing system controllers to dynamically adjust fan speeds to balance thermal demands and energy consumption.
-
Integrated Speed Sensor (Tachometer): Features a built-in frequency generator (FOO) wire that transmits real-time RPM data directly to PLC controllers or motherboards for diagnostic tracking.
-
Premium Die-Cast Aluminum Frame: The round 172mm frame is built from high-strength aluminum to handle the torque and vibrations of the high-speed 8000 RPM motor.
-
Locked Rotor Protection: Equipped with smart automatic shutdown circuitry that cuts off current if the rotor becomes physically blocked by debris, preventing motor burnouts and electrical short circuits.
Applications and Usage of Delta Cooling Fan THB1748BG
The raw power, industrial-grade shielding, and massive static pressure of the Delta Cooling Fan THB1748BG make it ideal for extreme industrial environments:
-
Telecom Power Systems and Base Stations: Keeps vital transceivers, cellular equipment, and outdoor power cabinets within safe operational temperature limits.
-
High-Density Server Clusters and Data Centers: Installed in high-power racks where massive volumes of air must be constantly cycled to prevent thermal throttling.
-
Industrial Inverters and Motor Drives: Mounted on high-power variable frequency drives (VFDs) and solar power inverters to protect delicate switching electronics from heat fatigue.
-
Heavy-Duty Power Supplies: Used in industrial rectifier systems, medical imaging equipment, and large-scale battery charging hubs.
