Description
The Delta PFB0824DHE-F00 (also known as PFB0824DHEF00) is a heavy-duty, high-static pressure DC tubeaxial fan engineered in a standard 80 × 80 × 38 mm (3.15 × 3.15 × 1.50 in) form factor. Operating on a nominal 24 VDC bus (14.0 to 26.4 VDC), this four-pole brushless motor fan spins at 9000 RPM to deliver an exceptional 132.56 CFM (225.2 m³/h) of airflow against up to 2.030 in H₂O (505.7 Pa) of static head. Structural integrity is ensured through flame-retardant UL 94V-0 thermoplastic housing and impeller assemblies suspended on dual precision ball bearings rated for 90,000 hours of continuous duty at 40 °C. The unit includes an integrated open-collector Frequency Generator (FG) tachometer wire, auto-shutdown locked-rotor protection, and reverse polarity shielding for mission-critical industrial assemblies.
Key Features
- Extreme Static Pressure: Generates up to 2.030 in H₂O static head to overcome heavily restricted server chassis airflow.
- High-Volume Air Movement: Discharges 132.56 CFM peak airflow from a compact 80mm footprint at 9000 RPM operation.
- Precision Ball Bearings: Dual industrial ball bearing suspension ensures 90,000 hours of L10 operating life at 40 °C.
- Dedicated Tachometer Output: Features a third-wire open-collector frequency generator signal for continuous fan speed and rotation monitoring.
- Comprehensive Electrical Safeguards: Equipped with 96-hour burn-proof locked rotor impedance protection and reverse polarity power input shielding.

Applications
The Delta PFB0824DHE-F00 axial fan is specifically engineered for thermal abatement in dense 2U/3U enterprise server racks, telecom power rectifiers, and optical networking line cards. It serves as an essential active cooling component across high-power variable frequency drives (VFDs), industrial inverters, and automated robotics motion controllers encountering high back-pressure fin-tube heatsinks. System builders and MRO maintenance teams frequently deploy this unit within redundant switchgear enclosures, medical imaging compute cores, and harsh-duty factory automation cabinets.
