Technical Specifications
Round fan DA9238H12B dimensions drawing
The technical dimensional drawing outlines the precise mechanical dimensions and structural parameters for the DA9238H12B DC round fan. Featuring a compact 92x38mm circular housing design, this model is specifically engineered to fit seamlessly into small-diameter circular ductwork, cylindrical equipment enclosures, and space-constrained thermal chassis without requiring extra adapter brackets.
This blueprint illustrates critical physical specifications, including outer frame diameter, mounting pitch, casing thickness, and lead wire outlet alignment. Adhering to strict manufacturing tolerances ensures a perfect seal against perimeter air bypass, streamlines assembly for OEM thermal integration, and maintains structural integrity during continuous high-RPM operation.
Round fan DA9238H12B PQ curve
The Pressure vs. Discharge Airflow (P-Q) performance curve demonstrates the aerodynamic capability of the DA9238H12B round fan under varying static backpressure conditions. Driven by a high-torque brushless DC motor and equipped with dynamically balanced impellers, this unit maintains robust volumetric airflow (CFM) even when overcoming high internal resistance.
Thermal design engineers can utilize this performance chart to map system airflow demands against static pressure drops caused by tight component spacing, protective grilles, or inline air filters. The smooth performance curve reflects minimal aerodynamic stall, low acoustic noise generation, and maximum energy efficiency throughout continuous 24/7 duty cycles.
