24V DC Fan DA17225VH24B-A Mechanical Dimensions
The mechanical outline drawing illustrates the precise structural dimensions of the DA17225VH24B-A 24V DC fan. Standardized with a compact 172 x 150 x 25 mm frame, this slim-profile axial cooling fan serves as a direct drop-in replacement for Delta AFB1524 series fans, engineered for space-constrained industrial enclosures, power supplies, telecom cabinets, and server racks.
- 100% Drop-in Compatibility: Identical 172mm × 150mm × 25mm mounting dimensions and hole locations as standard Delta 17225 series.
- Mounting Hole Specs: Standardized mounting holes for fast, effortless OEM upgrade and replacement.
- Structural Integrity: High-durability PBT UL94V-0 plastic housing and impeller for superior flame resistance and high-temperature performance.
- Custom Wiring & Pinout: Lead wire lengths, 3rd wire signal options (Tachometer/FG, RD), and custom connectors available upon request.
24V DC Fan DA17225VH24B-A Airflow & Pressure Performance
The Airflow vs. Static Pressure (P-Q) performance curve provides essential fluid dynamic characteristics for system thermal design. The DA17225VH24B-A 24V DC fan delivers up to 246 CFM, matching or exceeding Delta equivalent models to overcome high backpressure caused by dense heat sinks or tightly packed enclosures.
- Aerodynamic Efficiency: Optimized 7-blade geometry balances high volumetric airflow with powerful static pressure capability.
- Thermal Workload Stability: Delivers linear and consistent cooling performance across high thermal impedance conditions.
- Acoustic & Power Balance: Precision-balanced motor ensures maximum heat dissipation efficiency with reduced operational vibration and noise.
- Wide Voltage Tolerance: Stable performance output across standard 18V~26.5V DC operating ranges.
