Technical Specifications
Round fan DA12038H12B-2600422 dimensions drawing
The mechanical dimensions drawing provides full engineering specifications for the DA12038H12B-2600422 DC round fan. Featuring a 120x38mm circular frame design, this model is specifically engineered to fit snugly into round ducts, cylindrical cooling housings, and specialized industrial chassis without necessitating custom transitions or flange adapters.
This blueprint outlines precise outer frame diameter measurements, mounting hole pitch, housing thickness, and lead wire exit locations. These strict engineering tolerances ensure ideal air sealing, prevent edge air bypass, and facilitate smooth integration for OEM thermal management systems and commercial ventilation assemblies.
Round fan DA12038H12B-2600422 PQ curve
The Pressure vs. Discharge Airflow (P-Q) performance curve illustrates the aerodynamic capabilities of the DA12038H12B-2600422 round fan under various static resistance pressures. Driven by a high-torque motor and precision-balanced fan blades, this unit maintains robust volumetric airflow even when facing substantial system backpressure.
System design engineers can utilize this performance chart to map required CFM output against static pressure losses induced by dense air filters, tight internal component layouts, or long duct runs. The optimized flow characteristics minimize acoustic resonance and aerodynamic stall, ensuring energy-efficient, continuous 24/7 thermal performance.
