Key Features
80 x 80 x 38 mm Frame
The fan uses an 80 mm square housing with 38 mm depth. Its mechanical format supports equipment requiring a high-airflow tubeaxial cooling fan with matching mounting and ventilation clearances.
7500 RPM Rated Speed
The manufacturer specifies a rotational speed of 7500 RPM at rated voltage. This high-speed design is intended for forced-air cooling systems that require substantial airflow through compatible electronic equipment.
107.30 CFM Maximum Airflow
The Delta PFB series specification lists 107.30 CFM maximum free-air flow and 1.368 inH₂O maximum static pressure. These values represent different endpoints of the fan performance curve.
Ball Bearing Construction
PFB0812UHE uses ball bearings with plastic frame and impeller components. Published acoustical noise is 61.0 dB(A), and the distributor-listed reference life is 50,000 hours at 40°C.
Two-Wire Base Configuration
The unsuffixed PFB0812UHE has two DC power leads and locked-rotor protection. The separately designated -F00 and -R00 variants add monitoring outputs, while -EP provides a different four-wire PWM-controlled configuration.
Applications
- Industrial power supply forced-air cooling
- Server and industrial computer chassis ventilation
- Telecommunications equipment thermal management
- Industrial control cabinet cooling
- Power electronics and inverter enclosure ventilation
- Network and communication equipment airflow systems
- Electronic test and measurement equipment cooling
- Maintenance of compatible 12 VDC 80 mm axial fan assemblies

Frequently Asked Questions
What is Delta Electronics PFB0812UHE?
PFB0812UHE is a Delta Electronics 12 VDC brushless tubeaxial cooling fan with an 80 x 80 x 38 mm housing, ball bearings and a two-wire electrical connection.
What is the rated voltage of PFB0812UHE?
The manufacturer specifies a rated voltage of 12 VDC and an operating voltage range of 7.0–13.2 VDC.
What are the physical dimensions?
The fan measures 80 x 80 x 38 mm. Verify the mounting-hole spacing, frame depth, airflow orientation and cable clearance against the existing equipment.
What is the rated input current?
The Delta PFB series catalog and DigiKey list a rated current of 1.55 A for the complete unsuffixed PFB0812UHE model.
What is the rated input power?
The manufacturer specifies 18.60 W input power at rated voltage. Electrical supply and wiring should be selected using the appropriate equipment design requirements.
What is the rotational speed?
Delta specifies 7500 RPM for PFB0812UHE. The -F00 and -R00 versions share this cataloged reference performance, while the different -EP version is rated at 6550 RPM.
What is the maximum airflow?
The manufacturer lists 107.30 CFM (3.038 m³/min) maximum free-air flow. Actual installed airflow depends on airflow restrictions and the equipment's pressure-flow characteristic.
What is the maximum static pressure?
The specified maximum static pressure is 1.368 inH₂O (34.75 mmH₂O), approximately 340.8 Pa. Maximum static pressure is measured at zero airflow, not simultaneously with maximum free-air flow.
What is the acoustical noise rating?
The manufacturer lists 61.0 dB(A). Acoustic measurements are made under specified free-air test conditions, and noise in an installed enclosure may differ.
What bearing type and reference lifetime are specified?
PFB0812UHE uses ball bearings. DigiKey lists a reference lifetime of 50,000 hours at 40°C, which is a test-based reference rather than a guaranteed service duration.
What is the difference between PFB0812UHE, -F00, -R00 and -EP?
The unsuffixed PFB0812UHE is a two-wire fan with locked-rotor protection. PFB0812UHE-F00 adds speed-feedback output, PFB0812UHE-R00 adds a locked-rotor status signal, and PFB0812UHE-EP is a separate four-wire PWM and tachometer version with IP56 protection, 0.99 A current and 91.87 CFM airflow.
What should be checked before ordering Delta PFB0812UHE?
Confirm the complete model number and suffix, 12 VDC supply, 1.55 A current rating, 80 x 80 x 38 mm frame, 7500 RPM rated speed, 107.30 CFM airflow requirement, mounting pattern, two-wire termination, environmental requirements and product lifecycle status. Alternative models should be evaluated separately for electrical and mechanical compatibility.
