Technical Specifications

Duct fan DA14038H12B-B dimensions drawing
The mechanical dimensions drawing details key structural specifications for the DA14038H12B-B DC duct fan. Featuring a 140x38mm circular casing design, this unit is engineered for direct inline mounting into ventilation ductwork, circular exhaust systems, and enclosed industrial equipment chassis without requiring custom adapter flanges.
This technical drawing illustrates outer frame diameter parameters, mounting hole pitch, housing thickness, and lead wire harness output orientation. Maintaining tight engineering tolerances guarantees an airtight seal against perimeter air leaks, streamlines integration for OEM equipment manufacturers, and maintains structural stability during continuous high-speed operation.

Duct fan DA14038H12B-B PQ curve
The Pressure vs. Discharge Airflow (P-Q) performance curve demonstrates the aerodynamic capabilities of the DA14038H12B-B duct fan across varying static backpressure levels. Powered by a high-torque brushless motor and fitted with dynamically balanced impellers, this inline duct fan delivers strong volumetric airflow (CFM) even when operating against significant airflow resistance.
Thermal management engineers can reference this performance graph to evaluate target CFM output against static pressure losses caused by restrictive duct channels, inline dust filters, or protective grilles. The optimized aerodynamic flow profile eliminates blade stall turbulence, reduces acoustic resonance, and delivers reliable energy efficiency for 24/7 continuous duty cycles.
