The FD3G146-24GL-90 is a high-torque dual-inlet centrifugal DC fan engineered for applications demanding balanced airflow and robust static pressure. Featuring a unique dual-inlet design and 38-blade galvanized steel impeller, it delivers efficient cooling (1,200 m³/h) at low noise (66 dB(A)) while operating on 24V DC power. Ideal for compact industrial systems requiring uniform air distribution.
Dual-Inlet Airflow Optimization
Dual air intakes enhance airflow symmetry and reduce turbulence, achieving 425 Pa static pressure for consistent cooling in confined or densely packed enclosures.
High-Density Impeller Design
38 galvanized steel blades maximize air displacement efficiency at lower RPM (1,700), minimizing noise while maintaining torque for demanding environments.
Industrial-Grade 24V DC Operation
Wide voltage tolerance (16–28V DC) with built-in protections (thermal shutdown, reverse polarity) ensures reliability in fluctuating power conditions (–25°C to 60°C).
Medical Equipment: MRI machines, diagnostic analyzers, sterilization units.
Lab Instruments: Environmental chambers, chromatography systems.
Compact Industrial Gear: Laser systems, 3D printing enclosures, power converters.
Q1: Why dual inlets vs. single inlet?
A: Dual inlets reduce airflow resistance, improve balance, and lower noise in space-constrained installations.
Q2: Can this fan handle dusty environments?
A: IP44 rating protects against particulate ingress, but avoid direct exposure to heavy dust/oil.
Q3: Is the high blade count (38) inefficient?
A: No—blade geometry optimizes pressure generation at low RPM, reducing energy use vs. high-RPM fans.
Q4: How is speed monitored?
A: White FG wire outputs 4 pulses/revolution for real-time RPM feedback via PLCs or controllers.
