AI-Powered supplier vetting

SummaryThe supplier focuses exclusively on EC fan and intelligent energy-efficient motor and fan solutions. It offers ODM services, multiple forms of customization, and reports new products within the past year, but does not provide 3D software design services or SDKs. Production data lists capacities for five fan categories and two production lines, while the supplier states that it is expanding semi-automatic and automatic assembly capabilities. Quality and service procedures are documented with follow-up records, and ISO 9001, ISO 14000, and ISO 45001 systems are referenced. However, the supplier lacks in-stock, overseas warehouse, overseas showroom, overseas agent or branch capabilities, and has no valid manufacturing-capacity contract with related subcontractors. Financial credibility and customer cases are insufficiently evidenced.

Supplier typeThe supplier describes itself as focused exclusively on EC fans and intelligent energy-efficient motor and fan solutions. Its stated operations include motor and fan assembly lines and related production equipment, indicating a specialized manufacturer rather than a general trading supplier.

CertificationsThe supplier states that it has adopted an ISO 9001 Quality Management System for ten years and is adopting ISO 14000 Environmental Management and ISO 45001 Occupational Health and Safety Management systems. The slices do not provide certificate numbers, validity dates, or scope details, but they explicitly identify these management systems.

After-Sales capabilityThe supplier has documented corrective/preventive action and customer-complaint procedures with follow-up records, and describes an agent/distributor network and online service team supporting technical and after-sales needs. However, it reports no overseas agents or branches, overseas warehouse, overseas showroom, or in-stock service capacity, limiting the demonstrated breadth of physical after-sales support.

R&D capabilityThe supplier reports new products within the past year, offers ODM services, and provides customization from samples, designs, and full or minor requirements. It does not provide 3D software design services and has no available SDK, so innovation capability is demonstrated mainly through product development and engineering customization rather than software tools.

Production capacityReported annual capacities are 10,000 DC axial fans, 50,000 centrifugal fans, 5,000 single-inlet centrifugal blowers, 8,000 dual-inlet centrifugal blowers, and 80,000 EC fans, supported by two production lines and ongoing investment in automated assembly. Constraints include no valid manufacturing-capacity contract with related subcontractors, no continuous batch quantity reconciliation, and no outsourcing SOP.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is reinforced by its stated R&D and design-service capabilities, although no 3D software design service is available.

Product Q&A

Q:What are the advantages of EC motors?

EC motors offer 80% high efficiency, use less than half the electricity of traditional motors, run cooler for longer life, and allow software-controlled speed optimization.

Q:How does the cost compare to traditional motors?

While initial cost is higher due to electronics, huge energy savings and lower operating costs provide payback periods as short as a few months.

Q:What is the rated voltage and operating range?

The rated voltage is 48VDC, with an operating voltage range of 36-57VDC.

Q:What protection features are included?

The fan includes locked-rotor protection, reverse polarity protection, over-voltage protection, and an IP44 protection type.

Q:Is customization available for this fan?

Yes, we offer full customization, minor customization, and flexible customization from samples or designs.
