AI-Powered supplier vetting

SummaryThe supplier is identified as a professional technical supplier with 3D software design, customization, ODM, SDK, and recent new-product development capabilities. It holds ISO9001:2015, ISO45001:2018, and ISO14001 certifications, and has documented procedures for corrective actions and customer complaints. However, evidence indicates limited operational scale: one production line, one quality inspector, one year of export experience, no inventory, no overseas warehouse, no overseas agents or branches, and no valid manufacturing-capacity contract with affiliated subcontractors. Financial results include a stated operating loss, but monetary figures are omitted here. Customer cases and named reference customers are not provided.

Supplier typeThe supplier is explicitly described as a professional technical supplier. Its stated business scope covers mechanical and electrical equipment, industrial control systems, electrical instruments, electronic products, chemical products subject to applicable exclusions, solid waste treatment, and rolling processing.

CertificationsThe supplier reports holding ISO9001:2015, ISO45001:2018, and ISO14001 certifications. These stated certifications provide explicit evidence of quality, occupational health and safety, and environmental management certification.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and customer complaints, supporting structured service handling. However, it reports no inventory, overseas warehouse, overseas showroom, overseas agents or branches, and no participation in offline trade shows, indicating limited overseas service infrastructure.

Financial creditFinancial information is reported for the last two years, but the latest stated operating profit is negative. This is explicit evidence of profitability weakness, while the available slices do not establish broader financial stability or creditworthiness.

R&D capabilityThe supplier reports 3D software design services, SDK availability, ODM services, and new products developed during the past year. These capabilities explicitly support product development and technical innovation, although the supplier does not provide OEM services for popular brands.

Production capacityThe supplier reports one production line and one quality assurance or quality control inspector, with finished products checked by packing staff. It also lacks inventory capacity and has no valid manufacturing-capacity contract with affiliated subcontractors, indicating limited and potentially less resilient production capacity.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same range is reported in both technical design and design-services information, providing strong evidence of broad customization coverage.

Product Q&A

Q:What is a three-lobe roots blower used for?

It is widely used for sewage treatment aeration, aquaculture oxygenation, pneumatic material conveying, dust removal, desulfurization and industrial ventilation. It supports 24-hour continuous operation for various medium and low pressure air supply scenarios.

Q:Is your roots blower oil-free type?

Yes. The rotor operates without mechanical contact, no oil participates in air compression. The output air is 100% oil-free and clean without secondary pollution.

Q:What are the main materials of the blower?

Casing and wall plates adopt HT250 high-strength cast iron; rotors adopt alloy cast steel; main shaft adopts 40Cr steel; sealing parts adopt nitrile rubber or fluorine rubber for anti-leakage and anti-aging.

Q:Can the blower run 24 hours continuously?

Yes. It adopts S1 continuous working system, professional industrial-grade structure and high wear-resistant parts, fully suitable for long-time non-stop industrial production.

Q:What is the noise level of the roots blower?

The standard operating noise is 70-80dB. Equipped with standard silencer. Noise can be reduced below 70dB with an optional soundproof cover.
