Purchase Information

We support online purchase inquiries for the SUNON EF92251S3-1Q040-F99 DC axial fan. For bulk purchases or inquiries about other industrial cooling products, please contact our team with your requirements. Before ordering, confirm the complete model number, 12 VDC rating, listed 1.73 W power consumption, frame dimensions, number of wires, connector type and signal requirements. If you are replacing an existing fan, compare the label, wiring, mounting arrangement and airflow direction to help ensure compatibility.

Frequently Asked Questions

What is SUNON EF92251S3-1Q040-F99?
It is a SUNON-branded DC axial cooling fan listed by a commercial supplier with a 92 x 92 x 25 mm frame, 12 VDC supply and 1.73 W power consumption.

What is the rated voltage of EF92251S3-1Q040-F99?
The exact-model commercial listing specifies 12 VDC. The allowable operating voltage range and startup voltage for the complete 1Q040-F99 configuration were not independently verified.

What are the dimensions of this fan?
The supplier lists nominal dimensions of 92 x 92 x 25 mm. The standard EF series drawing also shows an 82.5 mm nominal mounting-hole spacing, but the actual 1Q040-F99 assembly should be checked before using this measurement for installation.

What is the power consumption?
A supplier lists 1.73 W at 12 VDC. Dividing the listed power by the rated voltage gives a calculated current of approximately 144 mA. The calculated current should not be treated as a verified maximum or startup current.

What is the rated speed?
A manufacturer-confirmed RPM value for EF92251S3-1Q040-F99 was not independently located. The standard EF92251S3-1000U-A99 model is listed at 2400 RPM, but it is a different part-number configuration and its speed should not be assumed to apply here.

What airflow and static pressure does this model provide?
Exact-model airflow and maximum static pressure ratings were not independently verified. The standard EF92251S3-1000U-A99 values of 39.5 CFM and 0.10 inH2O should not be transferred to the 1Q040-F99 version without a matching technical specification.

How noisy is the EF92251S3-1Q040-F99?
A verified noise rating for the complete 1Q040-F99 model was not located. The 28 dB(A) figure listed for the standard EF92251S3-1000U-A99 applies to that separate configuration, not automatically to this product.

Does this model have two wires or three wires?
An exact-model supplier lists a three-wire configuration, while commercial product pages also offer selectable wire and connector options. Confirm the specific configuration being supplied rather than relying on the model number alone.

What does the F99 suffix mean?
SUNON EF-series suffix guidance associates F99 with a three-wire RD-type signal configuration. However, the exact signal definition, wire assignment and connector supplied with the 1Q040-F99 version should be verified against its documentation. Do not assume that the third wire provides standard FG tachometer output or PWM speed control.

What bearing system does this fan use?
The bearing construction of the exact EF92251S3-1Q040-F99 configuration was not independently verified. Other EF92251S3 models can have different suffixes and bearing configurations, so their specifications should not be used as proof of this model's bearing type.

What should be checked before ordering EF92251S3-1Q040-F99?
Verify the complete model number, 12 VDC supply, 1.73 W listed power, 92 x 92 x 25 mm dimensions, mounting-hole spacing, wire count, connector, signal assignment, airflow direction, rated speed and airflow requirements. Exact-model RPM, airflow, static pressure, noise and bearing details remain unverified. If the fan is being used in a critical system, request a matching manufacturer datasheet or confirm the actual product label and wiring before purchase.
