Airflow through your enclosure
Evaluate the fan with your enclosure, intake grille and exhaust path. Check clearance, mounting and connector requirements before comparing speed options.
Match the fan to your installation space, airflow requirement and acoustic target. Confirm the exact configuration and its operating point for your equipment.

Match the fan to your installation space, airflow requirement and acoustic target. Use the checks below to shortlist the correct configuration before requesting a quote or sample.
Evaluate the fan with your enclosure, intake grille and exhaust path. Check clearance, mounting and connector requirements before comparing speed options.
The listed dimensions are 120*120*25mm. Verify hole positions, clearance and airflow direction against the drawing before installation.
This page lists a 12V rated supply. Check the selected model’s operating voltage, current and power before connecting it to your system.
Compare the listed airflow with the flow required at your system’s operating pressure.
Evaluate noise in the installed equipment, including the enclosure, mounting and operating speed.
Request the P–Q curve for the exact model and operating voltage. Send your target airflow and pressure so we can help evaluate the match.
Maximum airflow and maximum static pressure describe different points on a P–Q curve. They are not achieved simultaneously. Select one complete model variant and evaluate it with your actual air path.
| Installation | Request the dimension drawing and connector pinout for your selected configuration before finalizing the mechanical design. |
|---|---|
| Electrical supply | This page lists a 12V rated supply. Check the selected model’s operating voltage, current and power before connecting it to your system. Include startup requirements and supply tolerances in your inquiry. |
| Operating environment | Share ambient temperature, humidity, dust or moisture exposure and duty cycle. Confirm temperature and ingress protection requirements for the exact configuration. |
| Bearing selection | Listed bearing information: NSK ball bearing. Confirm the ordered bearing option, mounting orientation and expected operating conditions. |
| Control & monitoring | Confirm the functions, signal levels, wire count and pinout of your selected version. Do not assume every connector or wiring option includes every listed function. |
| Project requirements | Tell us your cable length, connector, speed-control and protection requirements. Ask which options can be supplied for this model, and request the relevant compliance documents for the ordered configuration. |
| Technical documents | Ask for the datasheet for the exact model and configuration in your inquiry. |
Compare the listed airflow with the flow required at your system’s operating pressure. Evaluate noise in the installed equipment, including the enclosure, mounting and operating speed. Share your thermal or airflow target, installation space and noise limit if you need help shortlisting a version.
Installed airflow depends on system resistance and the selected operating point. Request the P–Q curve for the exact model and operating voltage. Send your target airflow and pressure so we can help evaluate the match. Test the selected version with the actual enclosure, grille, filter or duct.
Include your connector specification, cable length, pinout and control requirements in the inquiry. We will review which options are available for HR-104B and confirm the configuration before quotation.
Request the reliability information, lifetime test conditions and compliance documents applicable to the exact model and configuration. Share operating temperature, duty cycle and your market requirements so the information can be reviewed for your project.
Ask for sample and production quotations with your quantity, configuration and destination. Confirm MOQ, availability, production lead time and warranty terms in the quotation for this order.
Send the information you already have. If your specification is still developing, describe the equipment and the problem you need to solve.
Ask for a model recommendation, configuration review, technical documents and a quotation covering price and delivery.
Submit your requirements for HR-104B. Include your selected variant, quantity and project requirements to request pricing, configuration guidance and delivery details.
