48V DC fan DA8025HV48B-A dimensions drawing
The structural engineering drawing above details the precise mechanical dimensions, mounting hole locations, and structural tolerances of the DA8025HV48B-A 48V DC cooling fan. Designed in a standardized 80mm x 80mm x 25mm frame, this axial fan is specifically built for heavy-duty industrial and thermal management environments where reliable mounting and structural rigidity are paramount.
Key mechanical features and structural specifications include:
- Standard Form Factor: 80 x 80 x 25 mm outer dimensions, offering exceptional versatility and seamless compatibility with standard server racks, power supply enclosures, and industrial control cabinets.
- Precision Mounting Holes: Standardized corner mounting hole spacing, ensuring straightforward, vibration-resistant installation using standard hardware.
- Durable Frame & Impeller Design: Reinforced PBT plastic housing (UL 94V-0 flame-retardant rating) providing high resistance to thermal deformation, mechanical stress, and harsh operating conditions.
- Dual Ball Bearing Assembly: Integrated high-precision dual ball bearing system that reduces friction, supports omnidirectional mounting orientations, and guarantees extended operational life under continuous 24/7 duty cycles.
Engineers and system integrators can utilize these detailed structural dimensions to streamline chassis layout planning and ensure proper clearance, airflow pathing, and thermal dissipation efficiency in OEM/ODM equipment.
48V DC fan DA8025HV48B-A PQ curve
The Performance Curve (PQ Curve) illustrates the key aerodynamic characteristics of the DA8025HV48B-A 48V DC fan, displaying the inverse relationship between volumetric airflow (Air Volume / CFM) and static head pressure (Static Pressure / mmH₂O or Pa) under a nominal 48V DC operating voltage.
Key performance highlights demonstrated by the PQ curve:
- High-Pressure Air Output: Capable of overcoming high system impedance, making it highly effective for pushing cool air through dense heat sinks, dust filters, and tightly packed electronic enclosures.
- Maximum Airflow Capacity: Delivers exceptional CFM output at free discharge (zero static pressure), allowing rapid hot air extraction from high-power thermal systems.
- Optimized Operating Efficiency Zone: Shows a wide operating region where the fan operates at peak aerodynamic efficiency, maintaining low acoustic noise while optimizing power consumption.
System thermal designers can consult this P-Q curve to accurately match fan pressure output against total enclosure system resistance, ensuring optimal cooling capacity and long-term hardware stability.
