AI-Powered supplier vetting

SummaryThe supplier manufactures and sells ventilation and dust-removal equipment, valves, fans, and related mechanical products, with offered products including fog cannons, centrifugal fans, and axial-flow fans. It reports ISO9001:2015, ISO45001:2018, ISO14001, and CE-related certification capabilities. Service procedures, complaint handling, and corrective/preventive-action records are stated to exist. The supplier reports six R&D engineers, new products in the past year, ODM, sample-based customization, and OEM service for well-known brands. Manufacturing information includes five production lines, but continuous quantity reconciliation is not performed. Financial records are identified for 2021–2023, without sufficient performance detail for a financial assessment. Overseas infrastructure is limited, with no overseas warehouse, showroom, agent, branch, or offline trade-show participation reported. No Fortune 500 collaboration is reported, although repeat-buyer preference is stated at 80%–100%.

Supplier typeThe supplier is a manufacturer and seller of ventilation equipment, spray dust-removal equipment, valves, fans, oil-fume purification equipment, and related mechanical products. Its stated products include fog cannons, centrifugal fans, and axial-flow fans, and it reports more than 12 years of fan design, research, and manufacturing experience.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, plus CE product-certification capability. These stated certifications support a positive assessment, although the slices do not provide certificate validity dates or scope details.

After-Sales capabilityThe supplier reports written and followed procedures for service capability assessment, corrective and preventive actions, and customer complaint handling. However, it reports zero countries with overseas services and no overseas warehouse, showroom, agent, or branch, indicating documented service processes but limited overseas service infrastructure.

R&D capabilityThe supplier reports six R&D engineers, new products launched in the past year, product-related R&D capability, and ODM services. It also reports no available SDK, but SDK availability is not essential evidence for the core fan and dust-removal equipment category.

Production capacityThe supplier describes itself as a manufacturer with more than 12 years of fan manufacturing experience and reports five production lines. However, it does not continuously reconcile quantities for every batch or mass-production run, which is a stated production-control weakness.

Customization capabilityThe supplier reports customization from samples, ODM service, and OEM service for well-known brands. These explicit capabilities support an assessment that it can undertake customized and externally specified product manufacturing.

Product Q&A

Q:Can the components of the equipment be customized?

All products under Zhengtong support customized services, which can be replaced or equipped with accessories according to customer needs. The power supply type can also be modified according to customer requirements.

Q:The exhaust gas in my factory contains corrosive chemicals. Will a standard carbon steel fan work, or do I need a special material?

Standard carbon steel fans are not suitable for corrosive environments as they will rust quickly. For chemical exhaust, we strongly recommend using Stainless Steel (SS304 or SS316) or FRP (Fiberglass Reinforced Plastic). These materials offer excellent resistance to acid and alkali corrosion. We can also apply a special anti-corrosion coating if the concentration is low. It is crucial to confirm the gas composition to avoid equipment failure.

Q:I am worried about the noise and vibration affecting the workshop environment. What solutions do you offer?

All our fans undergo strict Dynamic Balancing tests before leaving the factory to minimize vibration. To further reduce noise, we can install Inlet/Outlet Silencers or a Soundproof Enclosure. Additionally, mounting the fan on Vibration Isolators (rubber pads) will effectively prevent vibration from transferring to the building structure. We can customize the noise level to meet your local environmental standards.

Q:What is the warranty period for the centrifugal fan?

We provide a one-year warranty along with lifetime maintenance services for all our industrial centrifugal fans.

Q:How is the product packaged for overseas shipping?

All fans are packed with reinforced export-special packaging including waterproof and dust-proof film, shockproof bubble cotton, and sturdy multi-layer plywood export wooden cases that are fumigation-free and meet international quarantine standards.
