AI-Powered supplier vetting

SummaryThe supplier demonstrates broad customization and product-development capabilities, including ODM service and new products introduced within the past year. It operates four production lines, reports annual centrifugal-fan output of 20,000 sets, and has six quality inspectors, with peak- and off-season lead times within 15 working days. Certifications include ISO9001:2015, ISO45001:2018, ISO14001, and CE. Quality, supplier-service, corrective-action, and complaint-handling procedures are documented and followed. The supplier also provides OEM services for well-known brands and exports 21%–30% of sales, although its stated overseas service coverage is zero. Financial evidence is insufficient for a reliable assessment because the supplied financial indicators are non-informative or unclear.

CertificationsThe supplier holds ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, plus CE product compliance certification. These explicitly demonstrate established quality, occupational-safety, environmental, and product-compliance certifications.

After-Sales capabilityThe supplier has written and followed procedures for service assessment, corrective and preventive actions, and customer complaints. However, the stated overseas service coverage is zero, so the evidence supports formal service processes but not broad overseas after-sales coverage.

R&D capabilityThe supplier reports that it introduced new products during the past year and provides ODM services, demonstrating product-development activity. It does not have an available SDK, but SDK availability is not sufficient by itself to negate the documented R&D and ODM capabilities.

Production capacityThe supplier operates four production lines, lists laser cutting, shot blasting, CNC, boring and milling, welding, and painting equipment, and reports 20,000 centrifugal-fan sets of annual output. Six quality inspectors, standardized finished-product inspection instructions, and lead times within 15 working days support a developed production and quality-control capability.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are stated consistently across the R&D and production information, indicating broad customization coverage.

Client casesThe supplier explicitly states that it provides OEM services for well-known brands, which is evidence of at least one category of recognized-brand customer engagement. No specific customer names, project details, or performance outcomes are provided, limiting the depth of case verification.

Product Q&A

Q:Are your fans certified with international standards like CE, AMCA, or ATEX?

Yes. Our standard range is CE certified. We also offer AMCA-rated fans for performance assurance and ATEX/IECEx certified models for explosive atmospheres. Relevant certificates can be provided upon request.

Q:What is your Minimum Order Quantity (MOQ)? Can I order a single unit for testing?

MOQ for standard fans is 1 unit. Sample orders are welcome. Please note that samples are charged and shipping costs apply. Customized designs may have higher MOQs.

Q:Do you support OEM/ODM manufacturing? Can we use our own logo and packaging?

Absolutely. We are experienced in OEM/ODM projects. All details including branding, packaging, and technical specifications can be customized under a confidentiality agreement.

Q:How do you handle customization requests? What information do I need to provide?

Please provide: 1) Required air flow & pressure; 2) Operating medium and temperature; 3) Voltage & frequency (e.g., 480V/60Hz); 4) Installation environment; 5) Any special standards. We will then offer a tailored quotation and design drawing for approval.

Q:What is your warranty policy for international buyers? How do you handle technical support or repairs?

We offer a standard 18-month warranty from shipment date. We provide remote video support and can dispatch replacement parts promptly via international courier. For major issues, we can arrange for local service partners or engineer visits (terms apply).
