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 the pressure range of your screw blower?
A:
Our oil-free screw blower supports stable working pressure from 0.3 bar to 1.5 bar, suitable for low-pressure industrial aeration and conveying.
Q:How much energy can this blower save compared with traditional Roots blowers?
A:
Adopting magnet variable frequency control system, it can save 20%~35% of electricity consumption under actual working conditions.
Q:What is the noise level of the integrated blower unit?
A:
Equipped with fully enclosed silent cabinet, the running noise is controlled within 72-80dB, meeting indoor factory installation requirements.
Q:Can your blower deliver completely oil-free air?
A:
The dry-type screw host operates without lubricating oil inside the compression chamber, output air is pure and oil-free, complying with food and pharmaceutical clean gas standards.
Q:What is the maximum continuous running time of the blower?
