It is the ideal drop-in replacement or upgrade for server racks, control panels, welding machines, and heavy-duty custom electronics enclosures where reliable, continuous airflow is mandatory.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePeople also search for:\u003c\/strong\u003e hicool ec fan, 120mm 220v fan, b12038220h, electronically commutated fan, 4 inch panel fan, energy efficient cooling fan.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Hicool\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e B12038220H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan Type:\u003c\/strong\u003e EC (Electronically Commutated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 120mm x 120mm x 38mm (Standard 4-Inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 220V - 240V AC (50\/60Hz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type:\u003c\/strong\u003e Brushless DC (Internally converted from AC input)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Material:\u003c\/strong\u003e Die-cast Aluminum or High-Grade Flame Retardant Plastic (depending on batch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Terminal or Wire leads (requires AC wiring)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eApplications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Control Panels:\u003c\/strong\u003e Maintaining safe operating temperatures for PLCs, motor drives, and power supplies.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eServer Racks \u0026amp; Networking:\u003c\/strong\u003e Providing quiet, highly efficient airflow for home labs or commercial server cabinets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom Enclosures:\u003c\/strong\u003e Cooling high-power DIY projects like custom AC-DC power supplies or audio amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVentilation Systems:\u003c\/strong\u003e Exhausting fumes or heat from small 3D printer enclosures and laser cutter cabinets.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eFrequently Asked Questions (FAQ)\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the difference between this EC fan and a standard AC fan?\u003c\/strong\u003e\u003cbr\u003e\nA: A standard AC fan uses AC voltage directly to drive the motor, which is less efficient and generates more heat. This EC fan accepts AC voltage, but internally converts it to run a DC brushless motor. This results in up to 70% lower power consumption, quieter operation, and a longer lifespan.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I plug this directly into my wall outlet?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes, it is designed to run on standard 220V AC mains power. However, it usually comes with bare wire leads or standard fan terminals, so you will need to safely wire it to an AC power cord or a switched panel connection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Will this fit where my old 120mm PC fan used to be?\u003c\/strong\u003e\u003cbr\u003e\nA: The mounting holes follow the standard 120mm fan spacing, so it will fit the exact same mounting points. However, it is 38mm thick (standard PC fans are usually 25mm thick), and you must remember this requires 220V AC power, \u003cem\u003enot\u003c\/em\u003e the 12V DC power from a computer motherboard.\u003c\/p\u003e\n\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × Hicool 4-Inch EC Fan 120x120x38mm (B12038220H)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hi-Cool","offers":[{"title":"Default Title","offer_id":48336302309614,"sku":"FAN-17505","price":2990.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/ECFAN4INB12038220HHICOOL.jpg?v=1784286596","url":"https:\/\/www.tomsonelectronics.com\/products\/hicool-4-inch-ec-fan-120x120x38mm-b12038220h","provider":"Tomson Electronics ","version":"1.0","type":"link"}
