The ADNet 120mm (4-inch) AC Cooling Fan is a heavy-duty industrial component designed primarily for thermal management in server racks, networking cabinets, and electronic enclosures. Because it runs on standard 220V AC power, it is a “plug-and-play” solution for environments where a DC power supply isn’t available.
Core Specifications
Dimensions: 120mm x 120mm x 38mm (Standard 4-inch square).
Input Voltage: 220V – 240V AC (50/60Hz).
Construction: High-quality die-cast aluminum outer frame with theroplastic blades.
Bearing Type: Usually equipped with ball bearings for long-term continuous operation.
Airflow: High-velocity output designed to push hot air out of cramped rack spaces.
Key Features
1. Robust Metal Housing
Unlike plastic consumer fans, the ADNet model uses a metal body. This provides better heat dissipation for the fan itself and ensures it doesn’t warp or melt under the high-temperature conditions found in server rooms.
2. High Reliability
Designed for 24/7 operation, these fans are rated for tens of thousands of hours. The metal construction also provides EMI (Electromagnetic Interference) shielding, which is vital when placed near sensitive networking gear.
3. Easy Integration
Mounting: Standard four-hole mounting pattern compatible with most 1U to 42U server racks.
Wiring: Typically comes with lead wires or terminals that can be easily spliced into a power strip or a dedicated rack PDU (Power Distribution Unit).
Usage Scenarios
Server Racks: Exhausting heat from switches, routers, and UPS systems.
CNC Machines: Cooling control panels.
DIY Projects: Used in custom incubators, AV cabinets, or workstations requiring high-pressure airflow.
