AI-Powered supplier vetting

SummaryThe supplier is a combined company focused on blower, environmental-protection equipment, and gas or liquid separation and purification equipment, with related manufacturing, repair, and parts-processing activities. It demonstrates broad customization, ODM and OEM services, recent product development, documented R&D processes, CAD capability, and 20 R&D patents. Production data shows annual output for four blower product categories, while lead times are stated as within 15 working days in both peak and off-season periods. Overseas services include installation, debugging, repair, maintenance, and training, with Indonesia identified as an overseas service market. The supplier reports some brand OEM experience but no Fortune 500 cooperation. Certification details are insufficient, and its supplier-service assessment process lacks written procedures or followed records. Financial information only identifies years 2021–2023, without sufficient evidence to assess financial credibility.

Supplier typeThe supplier is identified as a combined company rather than an offshore company. Its stated scope covers fan and blower manufacturing and sales, environmental-protection equipment, gas compression machinery, liquid separation and purification equipment, general and special equipment manufacturing and repair, and mechanical parts processing and sales.

After-Sales capabilityThe supplier offers overseas debugging, repair, maintenance, training, and equipment installation, and identifies Indonesia as an overseas service market. However, its service-capability assessment has no written procedures or followed records, and only some approved-supplier names were provided, indicating service offerings are evidenced but service governance is incompletely documented.

R&D capabilityThe supplier reports new products during the past year, ODM services, two R&D engineers, CAD capability, 20 R&D patents, and documented design-input, output, review, verification, and validation records available for audit. It also reports no available SDK, which limits the evidenced software-development capability, but the overall product R&D evidence supports a positive assessment.

Production capacityReported annual output includes 10,000 rotary vane blowers, 2,000 air-bearing turbo blowers, 500 magnetic-bearing turbo blowers, and 10,000 Roots blowers. The supplier also states lead times within 15 working days in both peak and off-season periods and has uniformly followed finished-product inspection instructions, providing explicit evidence of production capacity and operational control.

Customization capabilityThe supplier explicitly offers customization from samples, full customization, customization from designs, flexible customization, and minor customization. It also provides ODM services, indicating broad product-design and adaptation support.

Product Q&A

Q:What is the working principle of this Roots blower?

It operates based on the synchronous rotation of two or three lobed rotors inside a casing, generating airflow by changing the volume of sealed chambers rather than internal compression.

Q:What are the main applications for this air pump?

It is widely used in wastewater treatment aeration, petroleum and chemical industries for gas lifting, aquaculture, and various industrial applications requiring stable air delivery.

Q:Can the product specifications be customized?

Yes, we offer flexible customization including dimensions, power (11-75kw), capacity, RPM, voltage, and noise levels. OEM and ODM services are also available.

Q:What is the minimum order quantity (MOQ)?

The minimum order quantity is 1 set.

Q:What is the lead time for production?

The average lead time is 5-7 days. During peak seasons, it may take within 15 workdays, while off-season lead times are also within 15 workdays.
