Technical Specifications
Round fan DA14038H12B-B dimensions drawing
The mechanical dimensions drawing provides precise engineering and structural specifications for the DA14038H12B-B DC round fan. Featuring a 140x38mm circular frame design, this model is engineered to mount seamlessly into round duct channels, cylindrical cooling shrouds, and industrial equipment chassis without needing transition adapters or custom mounting flanges.
This detailed diagram illustrates outer frame diameter, mounting hole center-to-center pitch, casing thickness, and lead wire outlet position. Adhering to strict dimensional tolerances ensures a tight seal against edge air leaks, simplifies physical integration for OEM ventilation equipment, and maintains structural durability under continuous operational stress.
Round fan DA14038H12B-B PQ curve
The Pressure vs. Discharge Airflow (P-Q) performance curve demonstrates the aerodynamic capabilities of the DA14038H12B-B round fan across various static backpressure resistance levels. Powered by a high-torque DC motor and fitted with dynamically balanced impellers, this model maintains high volumetric airflow (CFM) even under demanding airflow resistance.
Thermal management engineers can reference this performance curve to map required CFM output against static pressure drops caused by restrictive duct runs, dense dust filters, or compact chassis interiors. The optimized flow characteristics eliminate blade stall, suppress acoustic resonance, and deliver maximum energy efficiency for 24/7 continuous duty cycles.
