The FS3G133-48GL-70 is a compact DC centrifugal fan engineered for applications requiring quiet operation and efficient airflow in space-constrained environments. Featuring a high-density 38-blade galvanized steel impeller and optimized 48VDC BLDC motor, it delivers reliable cooling with minimal acoustic footprint while meeting CE, RoHS, and ErP2015 standards.
Ultra-Quiet Operation
Achieves industry-low 64 dB(A) noise levels through precision-balanced 38 blades and low-RPM design (2,000±5%), ideal for noise-sensitive environments like medical devices or offices.
Space-Efficient Performance
With a compact 133mm galvanized steel impeller, it generates focused airflow (220 m³/h) and static pressure (310 Pa)—perfect for cooling electronics in tight enclosures or slim-profile equipment.
Extended Voltage Tolerance
Maintains stable operation across 36–57VDC input ranges, eliminating need for voltage stabilizers in variable-power settings like mobile labs or field-deployed systems.
Maintenance-Ready Design
Corrosion-resistant galvanized steel construction paired with IP44-rated sealing ensures longevity in humid/dusty conditions, supporting 50,000-hour L10 lifespan.
Medical Equipment: MRI cooling, dental chair ventilation, diagnostic instrument thermal management.
Office Automation: Projectors, conference system cabinets, slim-server cooling.
Industrial Controls: PLC enclosures, instrumentation panels, low-clearance machinery.
Transportation: Train control units, electric scooter battery cooling.
Q: Can the galvanized steel impeller handle chemical exposure?
A: Yes—it resists mild corrosives (pH 5–9), but avoid strong acids/alkalis. For harsh environments, request optional stainless steel version.
Q: Is the FG output compatible with 5V logic systems?
A: Yes—use a pull-up resistor (1–10kΩ) to 5VDC. Signal outputs 2 pulses/revolution.
Q: How does blade count affect performance?
A: 38 blades increase pressure efficiency by 15% vs. standard designs while reducing turbulence noise.
Q: Minimum clearance for side air intake?
A: Maintain ≥50mm unobstructed space around inlet (§5 drawing) for optimal airflow.
