AI-Powered supplier vetting

SummaryAivyter is described as an established Chinese industrial-equipment business focused on screw air compressors, drilling jumbos, shotcrete equipment, and related machinery. The materials indicate three factories, nearly 200 employees, 20 technical R&D personnel, 70 after-sales technicians, ISO9001:2015 certification, export activity since 2011, and stated access to multiple export markets. Reported production and delivery indicators include an annual output value of 300 million yuan, off-peak lead times within 15 working days, and peak-season fulfillment within one month; the financial figure is not assessed here. The evidence supports meaningful technical, manufacturing, service, and international-trade capabilities. However, customization capability and customer-case depth are not sufficiently documented, while the available transaction evidence consists of one recorded buyer transaction and does not establish broad customer coverage.

Supplier typeThe supplier is presented as a China-based manufacturer and engineering-equipment provider engaged in R&D, production, sales, and service for compressors, drilling jumbos, shotcrete machines, and related equipment. However, one associated-company record classifies the business as a trading company, so the exact operating entity structure is mixed across the records.

CertificationsThe supplier explicitly reports holding an ISO9001:2015 management-system certificate. This is direct evidence of certification relevant to quality-management processes.

After-Sales capabilityThe company reports a 70-person after-sales service team, while its business scope explicitly includes service for industrial, engineering, and mining equipment. This directly supports substantial after-sales staffing and service coverage.

R&D capabilityAivyter explicitly undertakes R&D and reports 20 technical R&D personnel in one company description, 17 years of total R&D-engineer experience, and multiple equipment categories including oil-free, integrated, portable, and diesel-engine compressors. These details support an established technical-development capability.

Production capacityThe supplier states that three factories were established, with nearly 200 employees, and describes itself as engaged in equipment production. It also reports off-peak lead times within 15 working days and peak-season fulfillment within one month, supporting operational production capacity; the product records identify Aivyter production addresses.

Product Q&A

Q:Will the lubricated water rust the air system?

The pure water which conforms the drinking standard is used in the water lubricated oil free compressor, and the materials of parts are 304/316 stainless steel. So the water won't rust tge air system.

Q:Will the water affect the service life of bearing?

Use the nanometer SIC bearing and ceramic bearing, and the water as the lubricant for them directly, so there is no problem for the bearing.

Q:Will the efficiency of water lubricated oil free compressor reduce gradually?

The technology of air end is from Japan, we are the professional manufacturing enterprise who know the true essence of the single screw air end. We promised our customers 2 years of warranty for air end, and the service life is over 20 years. The efficiency will not reduce by more than 5%.
