AI-Powered supplier vetting

SummaryThe supplier is a professional technical manufacturer and exporter involved in mechanical parts, general and special equipment, electrical instruments, auto parts, mining machinery, CNC equipment, and related products. It reports R&D capability, SDK availability, 3D design services, ODM services, OEM experience for well-known brands, and broad customization options. Production information lists annual outputs of 100,000 ring blowers, 5,000 roots blowers, and 3,000 water ring vacuum pumps, supported by 11–20 quality-control staff and three R&D engineers. Written procedures and records are reported for supplier assessment, corrective and preventive actions, and customer complaints. However, no new products were launched in the past year, raw-material traceability status is unknown, and no overseas warehouses, showrooms, agents, branches, or offline trade-show participation are reported. Certification holdings and specific customer cases are not provided.

Supplier typeThe supplier identifies as a professional technical supplier and operates across equipment manufacturing, mechanical parts, mining machinery, CNC equipment, electrical instruments, and auto parts. Its stated business scope also includes import and export of goods and technology, indicating both manufacturing and trading/export activity.

After-Sales capabilityThe supplier reports written procedures and followed records for corrective and preventive actions and for handling customer complaints, and emphasizes customer service and satisfaction. These records provide explicit evidence of service-management processes, although overseas service infrastructure is absent according to the provided data.

R&D capabilityThe supplier reports professional R&D capability, 3D software design services, SDK availability, ODM services, OEM services for well-known brands, and multiple customization modes. Nevertheless, it also states that no new products were launched during the past year, and its product-information R&D response is negative, so recent innovation output is limited.

Production capacityReported annual output includes 100,000 ring blowers, 5,000 roots blowers, and 3,000 water ring vacuum pumps. The supplier also reports 11–20 quality-control staff, exports to South America, Southeast Asia/Mideast, and Europe, and an off-peak lead time of one month, providing explicit evidence of established production and export operations.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization, supported by professional R&D and 3D software design services. This indicates broad capability to adapt products to customer specifications.

Product Q&A

Q:Why is the noise level low?

The blower is installed underwater, which refracts operating noise into the water rather than the air, significantly reducing surface noise.

Q:Does it require a foundation?

No, the JSL/SRB series does not need to be fixed on a foundation, which saves piping costs and simplifies installation.

Q:What is the motor protection grade?

The motor features F-class insulation and an IP68 protection grade, with a built-in overheating detector to prevent burning out.

Q:How is the filtration system designed?

It uses a dry-type filtration device that won't distort under pressure. The filter area is 1.2 times the blower's air capacity, keeping pressure loss under 25mmAq.

Q:What are the customization options?

Customization is available for Color (Blue), Material (Casting Iron), Impeller (2-Lobe), and Drive type (Belt or Direct Drive).
