Overview of FK3G310-48AL-90 48V DC 135W 310mm Bracket Centrifugal Fan


The FK3G310-48AL-90 is a versatile backward centrifugal fan engineered for general industrial thermal management. Featuring a compact bracket design, 48VDC power input, and 135W consumption, it delivers 1206.425 CFM (2050 m³/h) airflow and 1.96 in.wg (490 Pa) static pressure. Built with an aluminum alloy motor and glass-fiber reinforced impeller, it balances durability, silence, and efficiency—making it a go-to for environments where consistent cooling is critical.


Key Features of FK3G310-48AL-90 48V DC Quiet Bracket Fan


Fashionable & Robust Build: Sleek design combines functionality with aesthetics; aluminum motor resists rust, while glass-fiber impellers withstand vibration.

Multi-Protection Suite: Includes soft-start, over/undervoltage detection, thermal overload, and reverse polarity protection to prevent motor damage.

Continuous S1 Duty: Rated for non-stop operation, ideal for 24/7 industrial processes like manufacturing lines or data center auxiliary cooling.


Application Solutions for FK3G310-48AL-90 General Industrial Fan


Small-to-Medium Factory Cooling: Cools assembly line machinery (e.g., welding equipment) without disrupting workflow, thanks to low noise (67 dB(A)).

Telecom Cabinet Thermal Management: Maintains optimal temperatures for routers and servers in outdoor telecom enclosures, protected by IP44.

Food Processing Auxiliary Ventilation: Removes excess heat from packaging machines, complying with hygiene standards via non-toxic impeller materials.

Performance Metrics of FK3G310-48AL-90

• Sound Pressure Level: 67±5 dB(A) (quieter than standard industrial fans, suitable for near-worker installations).

• Max Airflow: 2050 m³/h (sufficient to cover 50–80㎡ spaces with 3–5 air changes per hour).

• Life Expectancy: 50,000 hours (L10) at 40°C, 15–65% RH (reduces replacement frequency and maintenance costs).


Component Specifications of FK3G310-48AL-90

• Motor: External-rotor BLDC (brushless design, lower energy loss than AC motors).

• Lead Wire: Heat-resistant (max 120°C) to avoid insulation melting in high-temperature environments.

• Bearings: Ball bearings (higher load capacity than sleeve bearings, ideal for heavy-duty use).


Environmental Tolerance of FK3G310-48AL-90

• Operating Humidity: 5–90% RH (no condensation issues in damp warehouses).

• Storage Temperature: -40°C to 75°C (safe for long-term storage in cold or hot warehouses).


Technical Support for FK3G310-48AL-90 310mm Centrifugal Fan


Pre-Sale Consultation: Free airflow and pressure calculations to ensure the fan matches your system’s requirements.

Installation Support: Video tutorials and on-site guidance (for bulk orders) to simplify setup.

Replacement Parts: Fast delivery of impellers, bearings, and motors to minimize downtime.
