The FK3G355-48AL-20 is a heavy-duty DC centrifugal fan engineered for high-airflow industrial applications requiring robust performance. Featuring a large 355mm aluminum impeller and 48VDC operation, it delivers substantial airflow (3230 m³/h) with strong static pressure (810 Pa), making it ideal for large-scale ventilation systems. The integrated support bracket and IP44-rated construction ensure versatile mounting and reliable operation in demanding environments like factories or processing plants.
Industrial-Scale Air Movement
355mm aluminum impeller generates massive 3230 m³/h airflow—ideal for cooling large equipment or ventilating spacious areas. Optimized blade design maintains efficiency while reducing noise to 71 dB(A).
High-Pressure Capability
Delivers 810 Pa static pressure to overcome resistance in ducted systems, filtration units, or industrial processes without compromising airflow volume.
Rugged Aluminum Construction
Full die-cast aluminum impeller and housing resist deformation at high RPM (2000 min⁻¹) and withstand mechanical stress in harsh operating conditions.
Universal Bracket Mounting
Pre-installed support bracket enables flexible horizontal/vertical installation. IP44 protection guards against dust ingress and water splashes for outdoor/industrial use.
Industrial Ventilation: Large factory floors, welding bays, or chemical processing areas.
Material Handling: Dust collection in woodworking, grain processing, or recycling facilities.
HVAC Boosters: Supplemental airflow in commercial ducting systems.
Heavy Equipment Cooling: Ventilation for industrial ovens, generators, or compressors.
Q: Can it handle abrasive particles?
A: Aluminum construction resists mild abrasion. For heavy particulate loads, add inlet filters.
Q: What clearance is needed for installation?
A: Maintain ≥400mm clearance at intake/exhaust. Refer to dimensional drawings for space planning.
Q: Why choose aluminum over plastic impellers?
A: Superior durability at high speeds/stress. Ideal for continuous operation in 24/7 industrial settings.
Q: Is the bracket suitable for vibration-prone environments?
A: Yes. Add rubber isolators if mounted on vibrating machinery (e.g., compressors).
Q: Can two units operate in parallel?
A: Yes—doubles airflow at similar pressure. Ensure separate 48VDC power circuits.
