Technical Specifications
Duct fan DA9238H12B dimensions drawing
The technical dimensional drawing provides comprehensive structural and mechanical details for the DA9238H12B DC duct fan. Designed specifically for inline ventilation networks and circular air passages, this model features a compact 92x38mm housing footprint, allowing for straightforward installation within narrow duct lines, air purification channels, and enclosed ventilation housings.
This engineering blueprint outlines precise outer frame diameter parameters, mounting hole pitch, housing depth, and wire harness exit alignment. Maintaining these strict manufacturing tolerances ensures a tight mechanical seal against edge air leaks, simplifies physical mounting for OEM system integrators, and supports long-term structural reliability under continuous operation.
Duct fan DA9238H12B PQ curve
The Pressure vs. Discharge Airflow (P-Q) performance curve illustrates the aerodynamic capabilities of the DA9238H12B duct fan across various static backpressure resistance levels. Driven by a high-torque brushless DC motor and fitted with dynamically balanced impellers, this inline duct fan delivers stable volumetric airflow (CFM) even when overcoming high air resistance in restrictive ducting.
HVAC and ventilation design engineers can reference this performance graph to calculate volumetric air exchange rates against static pressure losses induced by inline filters, tight duct bends, or protective grilles. The optimized aerodynamic flow curve minimizes air stall turbulence, suppresses acoustic noise, and guarantees energy-efficient performance during 24/7 continuous duty cycles.
