Technical Specifications
Duct fan DA17251L12B-A dimensions drawing
The mechanical dimensions drawing provides comprehensive structural and physical specifications for the DA17251L12B-A DC duct fan. Designed with a large-format 172x51mm circular frame profile, this high-performance fan is engineered specifically for direct inline integration into circular ductwork, industrial ventilation networks, and commercial exhaust channels.
This technical diagram outlines key engineering dimensions, including precise outer frame diameter, mounting hole center pitch, casing depth, and lead wire harness exit location. Adhering to strict dimensional tolerances ensures a tight mechanical seal against edge air bypass, simplifies physical installation for OEM ventilation integrators, and maintains long-term structural durability.
Duct fan DA17251L12B-A PQ curve
The Pressure vs. Discharge Airflow (P-Q) performance curve illustrates the aerodynamic capabilities of the DA17251L12B-A duct fan under varying static backpressure resistance levels. Driven by a high-torque motor assembly and equipped with dynamically balanced impellers, this inline duct fan delivers sustained high-volumetric airflow (CFM) even when overcoming high air resistance in long duct runs.
HVAC and ventilation engineers can reference this performance graph to evaluate target CFM delivery against static pressure drops caused by inline air filtration, tight duct bends, or protective grilles. The optimized aerodynamic flow profile eliminates stall turbulence, dampens acoustic noise, and ensures energy-efficient cooling during continuous 24/7 duty cycles.
