Technical Specifications
Round fan DA13628H12B-A dimensions drawing
The mechanical dimensions drawing details the full structural specifications for the DA13628H12B-A DC round fan. Featuring a specialized 136x28mm circular frame design, this unit is engineered to fit directly into round duct openings, cylindrical cooling shrouds, and compact industrial chassis without requiring custom adapter plates.
This engineering diagram specifies outer frame diameter dimensions, mounting hole center distances, casing thickness, and lead wire outlet positions. These precise physical parameters ensure seamless mechanical alignment, eliminate air leakage around housing borders, and streamline assembly for OEM ventilation system integrators.
Round fan DA13628H12B-A PQ curve
The Pressure vs. Discharge Airflow (P-Q) performance curve illustrates the aerodynamic capabilities of the DA13628H12B-A round fan across varying static resistance pressure levels. Powered by a high-efficiency brushless motor and dynamically balanced impellers, this model maintains steady volumetric airflow even in high-backpressure environments.
Thermal engineers can reference this performance graph to evaluate target CFM delivery against static pressure drops caused by restrictive filters, internal component density, or narrow ducting. The optimized flow characteristics prevent aerodynamic stall, minimize noise resonance, and ensure energy-efficient cooling during continuous 24/7 operation.
