What this manufacturer offers
Zhejiang Shangyang Industrial Fan Co., Ltd. is the manufacturing entity behind a website that also presents Yuanxin Shangyang Fan (Shanghai) as a sales company. Its preserved CRM registration records fan, environmental equipment and coating-equipment manufacture, with establishment on 19 June 2019. The official contact page locates the Zhejiang company at 6–8 Bifa Road, Xinbi Street, Jinyun, matching the source address’s building-2 manufacturing site. The Shanghai reception photograph is not evidence of a Zhejiang production visit.
The reviewed offer includes stainless centrifugal exhaust, hot circulation, powder recovery, acoustic boxes and other distinct fan applications. Certificate images add specific evidence but need careful dates and model boundaries: one ISO 9001 image expired on 30 September 2026, and a CNEX image covers a stated explosion-protected model list rather than all advertised fans. This profile separates those evidence limits from supplier claims about staff, capacity and experience.

03 / PROJECT REVIEW
Match Shangyang to the process air and manufacturing evidence
Keep legal identity and claimed experience separate
Match quotations, manufacturing drawings and quality documents to the Zhejiang legal entity or explicitly named contracting party. The contact page presents the Shanghai sales company separately; its reception image does not prove a visit to the Zhejiang manufacturing floor or establish a legal parent/subsidiary relationship.
The CRM establishment date is 2019, while the website speaks of a twenty-year technical team. Preserve both scopes instead of rewriting the company as twenty years old. Verify the current workshop, scope of manufacture and responsible engineering contact before arranging a technical review.
Select the application before choosing a catalogue number
Distinguish stainless exhaust, hot-air circulation, powder recovery, acoustic enclosures and boiler/process duties. Their gas composition, temperature, dust loading and system resistance lead to different selections. An application category is not a complete curve, material specification or approval for every hazardous atmosphere.
Issue the actual volume/pressure point and density basis, normal/upset temperatures, contaminants and installation constraints. Require the selected fan curve, motor/drive arrangement, inlet/outlet drawing and service access. No platform capacity or maximum-temperature rating is inferred from a homepage slogan.
Read the quality certificate with its actual expiry
The ISO 9001 image identifies the Zhejiang company, manufacturing scope and a certificate valid to 30 September 2026. At this review it has expired. Obtain a renewed certificate and issuer status evidence before describing the company as currently certified. A historical image remains useful for identity/provenance but cannot establish current surveillance or certification.
Other quality/corporate honour images are not used as a substitute for renewal. A quality-management certificate also does not independently prove a selected fan’s pressure, corrosion resistance or emissions performance.
Restrict explosion evidence to the reviewed model and conditions
The displayed CNEX certificate names a BSY model and a listed SY-ZY range, marking Ex db IIB T4 Gb and GB/T 3836.1-2021 / 3836.2-2021. Its X suffix and notes require the complete certificate and applicable conditions. Do not apply it automatically to a SY-4-72 stainless fan, a different motor or a customer’s entire installation.
The image states IP20 at the inlet and IP10 at the outlet; these are not a whole-assembly IP67 claim. Confirm current issuer validity, exact order coverage, installation conditions and motor/drive protection with the appropriate engineer. The platform has not verified the certificate independently or certified any installation.
Request a manufacturing and acceptance file for the actual order
Supplier claims about staff, throughput, capacity and high-temperature/vibration performance need an evidence-defined scope. Ask for actual fabrication, balance and performance test records for the selected design, together with instrument/calibration information and witnessed acceptance options. The website’s customer counts are not independently verified references.
Close material grade, coating/seals, drive, accessory and test scope in the quotation. Current stock, lead time and independent operating results remain unknown. This individually written review uses original identity and certificate evidence without converting promotional claims into verified factory capability.
Match contracting and manufacturing entity
Resolve Zhejiang factory and separately presented Shanghai sales responsibility.
Approve duty and documentary scope
Obtain selected curves, materials and current model-specific documents.
Agree order tests
Define balance, duty, vibration and drawing/document acceptance.
