Product Overview

The FK3G355-48AY-20 is a heavy-duty bracket-mounted DC centrifugal fan engineered for industrial environments demanding high static pressure (580 Pa) and substantial airflow (3,350 m³/h). Featuring a robust 355mm aluminum impeller and 48V DC motor, it excels in confined spaces where mounting flexibility and corrosion resistance are critical. With IP44-rated construction and ultra-efficient operation, it’s ideal for harsh applications from mobile machinery to industrial ventilation systems.


Core Features

  1. Bracket-Mounted Versatility

    • Integrated mounting bracket enables tool-free installation in tight/angled spaces (e.g., equipment cabinets, vehicle frames).

    • Vibration-dampening design reduces noise transmission in metal enclosures.

  2. High-Pressure Industrial Performance

    • Aluminum impeller sustains 580 Pa pressure – conquering dense filters, long ducts, or exhaust bottlenecks.

    • Optimized 48V DC operation (36–57V range) suits solar/battery systems with 20% lower energy loss vs. AC alternatives.

  3. Smart Control & Durability

    • 0–10V/PWM input + tachometer (3 pulses/rev) enables precise speed tuning and real-time RPM feedback.

    • Sealed ball bearings and corrosion-resistant build ensure 50,000-hour lifespan in dusty/humid conditions.


Applications

  • Mobile Power Units: Cooling for generators, EV charging stations, or construction equipment.

  • Industrial Process Ventilation: High-resistance exhaust in welding, laser cutting, or powder coating systems.

  • Telecom/Energy Cabinets: Forced airflow in 5G base stations or battery storage enclosures.

  • HVAC Boosters: Supplemental pressure in large ducted systems with filter stacks.


FAQ

Q1: Can the bracket support outdoor installation?
A1: Yes. Aluminum construction resists corrosion, and IP44 rating protects against rain/dust ingress.

Q2: Why choose 48V DC over AC for industrial use?
A2: DC offers finer speed control, zero harmonic distortion, and direct compatibility with battery/solar power – critical for off-grid sites.

Q3: How does it handle high static pressure without noise issues?
A3: Precision-balanced impeller (G6.3) minimizes vibration, while low-RPM design (1,750) reduces acoustic fatigue.
