The FK3G175-48PY-71 is a 175mm diameter, 86W DC centrifugal blower featuring an external-rotor brushless DC motor (BLDC72). Designed for industrial and embedded systems, it operates on 48V DC power with a wide input range (36–57V DC). Its compact, bracket-mounted design delivers robust airflow (up to 715 m³/h) and reliable static pressure (610 Pa), ideal for demanding ventilation in confined spaces.
1. Motor & Drive System
Integrates an external-rotor DC motor directly coupled to the impeller, eliminating belts/gears. Uses ball bearings for extended service life (50,000 hours L10 at 40°C).
2. Performance Specifications
Generates 610 Pa maximum static pressure and 715 m³/h airflow. Maintains consistent pressure across operating ranges, suitable for restrictive systems like filtered ducts.
3. Acoustic Optimization
Operates at 73 dB(A) under full load. Aerodynamic blade design reduces turbulence noise, while motor encapsulation minimizes electromagnetic interference.
4. Power & Control Flexibility
Compatible with 36–57V DC inputs, accommodating voltage fluctuations in mobile/off-grid setups. Supports 0–10V DC or PWM speed control and provides tachometer output (FG signal) for real-time RPM feedback.
5. Protection & Safety
Includes:
Soft-start protection
Overvoltage/undervoltage cutoff
Thermal overload safeguards (motor/electronics)
Locked-rotor and reverse-polarity protection
IP44-rated against dust/water ingress
6. Mechanical Durability
Impeller: Glass-fiber reinforced polypropylene
Housing: Die-cast aluminum
Installation: Supports any mounting orientation
Weight: 3,600g (fan), 400g (inlet)
7. Compliance & Certifications
Meets CE, RoHS, ISO9001, and ErP 2015 standards. Validated for industrial EMC/safety (EN 61000, EN 60204-1).
Industrial Ventilation: Cooling for machinery, control cabinets, or enclosed systems.
Transportation HVAC: Electric vehicles or mobile equipment requiring compact, vibration-resistant airflow.
Filtration Systems: Pushing air through HEPA/carbon filters in medical or cleanroom environments.
Embedded Solutions: Space-constrained applications needing variable speed control (via PWM/0–10V).
