BEHIND THE DOCUMENTS
From airflow measurement to noise evaluation and production checks, test facilities support fan development and practical OEM integration. Explore selected facilities and equipment from LONGWELL’s published technical materials.
Wind-tunnel testing helps validate airflow and static-pressure performance at the intended operating point.
A semi-anechoic environment and microphone measurements support noise evaluation and low-noise fan development.
Controlled-temperature tests evaluate operation of the motor, insulation and bearing system under specified conditions.
Running-test setups support evaluation of fan operation over time and under specified test conditions.
Long-duration running tests support reliability evaluation. Results depend on the model, load and test conditions.
Prototype testing provides measured feedback for fan selection, design refinement and OEM integration.
CLEAR SCOPE. BETTER DECISIONS.
ISO certificates cover the named organization and stated activities. They do not replace product-specific safety or conformity documentation.
CE, ETL, RoHS and FCC documents apply to their listed models, ratings and scope. A report for one fan family is not blanket coverage for all products.
Tell us your model, supply voltage and destination country. Our team can check the applicable documents and discuss any additional verification required.
Social-compliance audits such as BSCI are distinct from product certification. Request the latest available audit information for supplier assessment. For REACH, ErP, UKCA or other project requirements, ask our team to check available evidence for the exact product and market.
Yes. Open a PDF or original scan using the document cards above, then save it using your browser. For additional reports, declarations or an up-to-date model-specific pack, contact our team.
No. These photos show testing facilities and equipment, not laboratory accreditation. Any third-party test or accreditation evidence must identify the issuing organization and its applicable scope.
Include the fan or motor model, voltage and frequency, airflow and pressure duty point, application, destination market and required documents. This helps our team check the correct configuration and evidence.
