The FB3G250-48PL-90 is a 250mm 85W centrifugal blower fan designed for demanding airflow systems. Powered by 48V DC, it integrates an external-rotor motor and impeller into a single compact unit. This unified design reduces installation space by 40% versus traditional split systems, making it ideal for constrained environments. Engineered to deliver high static pressure, it efficiently overcomes resistance in complex ductwork or multi-layer filtration setups.
Space-Saving Integration
Motor stator is fixed within the housing while the rotor directly drives the impeller.
Eliminates belts/gears, cutting energy loss by 30% and reducing vibration transmission by 25%.
High-Pressure Performance
HEPA filters (MERV 17)
10m ducts with 90° bends
Generates up to 800 Pa static pressure—capable of pushing air through:
Radial blade angle maintains stable airflow (500–1,500 m³/h).
Low-Noise Operation
Aerodynamically rounded blades reduce turbulence.
Encapsulated motor windings dampen electromagnetic noise.
Operates at 72 dB(A) (30% quieter than comparable blowers).
HVAC Systems:
Optimized for variable air volume (VAV) units in commercial buildings, dynamically adjusting airflow to meet zone-specific demands.
Filtration Systems:
Handles high-resistance environments like HEPA-filtered cleanrooms or industrial exhausts.
Mobile/Off-Grid Setups:
Reliable performance in voltage-fluctuating environments (e.g., solar-powered installations or electric vehicles).
