Key Features
80 x 80 x 25.4 mm Reference Frame
The manufacturer's QFR0812UH-CX14 drawing specifies an 80 mm square frame with a 25.4 mm depth and 71.5 mm mounting-hole spacing. Exact mechanical fit must be verified for other assembly versions.
5600 RPM CX14 Performance
Delta's CX14 approval specification identifies a 5600 RPM reference speed with ±10% tolerance at rated voltage. This rating is established for CX14 and should not be automatically applied to all QFR0812UH configurations.
70.24 CFM Reference Airflow
QFR0812UH-CX14 provides a published maximum free-air flow of 70.24 CFM and maximum static pressure of 0.551 inH₂O. These are separate endpoints of the fan pressure-airflow curve.
Dual Ball Bearing CX14 Design
The manufacturer CX14 specification identifies two ball bearings, UL 94 V-0 plastic housing and impeller materials, 50.5 dB(A) average acoustical noise and an 88 g reference weight.
Documented PWM and FG Option
The CX14 assembly has four wires: red positive, black negative, blue frequency-generator feedback and yellow PWM input. A base safety-model marking alone does not establish the wire count or control features of another version.
Applications
- Industrial electronic enclosure forced-air cooling
- Compact server and industrial computer ventilation
- Power supply equipment thermal management
- Network and telecommunications device cooling
- Embedded industrial controller ventilation
- Electronic test and measurement equipment cooling
- Equipment requiring compatible 80 mm axial fan assemblies
- Maintenance of matching Delta QFR0812UH cooling configurations

Frequently Asked Questions
What is Delta Electronics QFR0812UH?
QFR0812UH is a Delta Electronics safety-model designation for a DC brushless axial fan. Delta's QFR0812UH-CX14 approval specification explicitly identifies QFR0812UH as its safety model.
What is the rated voltage?
The documented QFR0812UH-CX14 configuration operates at 12 VDC. Its allowable operating voltage range is 10.8–12.6 VDC; this range is specific to CX14 and should not be assumed for every variant.
What are the fan dimensions?
Delta's QFR0812UH-CX14 drawing specifies an 80 x 80 x 25.4 mm frame with 71.5 x 71.5 mm mounting-hole spacing. Confirm physical dimensions for an assembly whose complete variant is not known.
What is the input current of QFR0812UH?
The QFR0812UH-CX14 manufacturer specification lists 0.55 A input current and 0.61 A maximum. Other configurations under the QFR0812UH safety designation require their own electrical specifications.
Why does a QFR0812UH-CX14 label show 0.87 A?
Delta identifies 0.87 A as the safety current shown on the CX14 label. The same approval document separately specifies 0.55 A operating input current and 0.61 A maximum. These quantities must not be confused.
What is the input power?
For QFR0812UH-CX14, Delta specifies 6.60 W input power and 7.32 W maximum. These values should only be assigned to a matching configuration.
What is the rated rotational speed?
The QFR0812UH-CX14 manufacturer approval specification lists 5600 RPM ±10%. A common speed rating for every unsuffixed QFR0812UH assembly was not independently established.
What is the maximum airflow?
Delta documents 70.24 CFM (1.989 m³/min) maximum free-air flow for QFR0812UH-CX14, with a minimum specified value of 63.21 CFM. Actual equipment airflow depends on airflow resistance.
What is the maximum static pressure?
The CX14 specification lists 0.551 inH₂O (13.99 mmH₂O) maximum static pressure. Maximum static pressure occurs at zero airflow, rather than simultaneously with the maximum free-air-flow value.
What are the bearing and noise specifications?
The manufacturer identifies two ball bearings, 50.5 dB(A) average acoustical noise and 54.5 dB(A) maximum for QFR0812UH-CX14. Other revisions should be checked separately.
Does QFR0812UH have PWM speed control and tachometer feedback?
The complete QFR0812UH-CX14 version has four leads for power, FG speed feedback and PWM input. The unsuffixed QFR0812UH designation alone does not confirm those features on every assembly.
What should be checked before ordering Delta QFR0812UH?
Confirm the complete model identifier and suffix, 12 VDC supply, applicable rated and maximum current, actual frame thickness, mounting-hole pattern, fan speed, airflow requirements, ball bearing specification, wire count, connector type, PWM compatibility and frequency-generator signal connections.
