Technical Specifications
Duct fan DA12038H12B-2600422 dimensions drawing
The detailed dimensional drawing outlines key mechanical and structural specifications for the DA12038H12B-2600422 DC duct fan. Featuring a standardized 120x38mm circular frame profile, this unit is engineered specifically for direct inline insertion into ventilation pipes, circular ducts, and enclosed equipment chassis without needing custom adapter flanges.
This engineering blueprint provides exact parameters for the outer housing diameter, mounting hole pitch, casing depth, and wire harness outlet direction. Adhering to strict dimensional tolerances ensures an airtight fit against perimeter air bypass, streamlines assembly for OEM thermal integration, and maintains mechanical stability during continuous high-RPM operation.
Duct fan DA12038H12B-2600422 PQ curve
The Pressure vs. Discharge Airflow (P-Q) performance curve illustrates the aerodynamic capabilities of the DA12038H12B-2600422 duct fan under varying static backpressure conditions. Powered by a high-efficiency motor and fitted with dynamically balanced impellers, this inline fan maintains strong volumetric air delivery (CFM) even when overcoming high airflow resistance.
HVAC and thermal design engineers can utilize this performance graph to evaluate required CFM output against static pressure losses induced by inline carbon filters, tight duct elbows, or protective grilles. The optimized aerodynamic flow curve minimizes blade stall turbulence, reduces acoustic noise generation, and guarantees energy-efficient performance during continuous 24/7 duty cycles.
