01 / COMPANY
What this manufacturer offers
Zhejiang Jiayi Fan Co., Ltd. is the exact legal name matched to a preserved Tianyancha CRM source row. That source records a 2020-07-17 establishment date and business scope including fan, motor and related mechanical/electrical manufacturing. The associated official website uses the same legal name and Jiayi logo and provides original illustrated fan catalogues. Its HVAC-relevant offer includes DKT double-inlet air-conditioning fans, CDR round duct fans and YWF external-rotor fans used with refrigeration equipment.
The current website describes a business beginning in 2003 and a later manufacturing history. That may concern a predecessor or brand, but no continuity document was reviewed. This profile therefore keeps the current legal entity's source date separate from the supplier's history claim. It is a procurement research profile, not an on-site factory audit or a verification of every promotional number on the website.

03 / PROJECT REVIEW
Evaluate Jiayi's actual fan offer and manufacturing evidence
Use this supplier for fan duties that its actual catalogue supports
The reviewed catalogue includes fans for air-conditioning cabinets, round ducts and refrigeration coils. Shortlist a family by its actual duty and construction: double-inlet centrifugal airflow in an OEM cabinet differs from coaxial duct ventilation and square-frame axial airflow through a condenser or evaporator. Specify the intended air path and resistance before asking for a model.
The website also markets screw air compressors and other industrial equipment. Those categories are not treated here as evidence of a refrigeration-compressor offer, and unrelated compressor models are excluded from this HVAC selection. For a custom fan assembly, identify which motor, impeller, casing and controls the factory makes or buys, and request the final bill of construction.
Resolve legal history and the real production address
The original CRM source records the present legal entity's establishment in July 2020, whereas the website says it began in 2003. Obtain a current business licence, contracting name, registered address and any predecessor/brand continuity explanation. Do not turn an unreviewed brand-history statement into a verified legal incorporation date.
The source row lists a Daxi North Road registered address, the contact page gives Liangshan industrial park, and the external recruitment profile gives Dong'an industrial area. They can have different purposes, but no correspondence was established. Arrange any visit against an explicitly confirmed manufacturing address and equipment list rather than assuming a registration or recruiting address is the production floor.
Prioritise original technical documents over repeated website prose
The product pages repeat paragraphs and contain abbreviated HTML tables. The original illustrated catalogue sometimes differs substantially: the DKT 10-63 row shows 2,300–2,900 m³/h in the image, while the HTML transcription shows 3,100–6,100. YWF rows also differ in power, airflow and pressure. The product briefs preserve those conflicts rather than presenting a merged specification.
Require a current signed selection sheet with fan curve, speed, density, static/total pressure basis, motor input, sound-test basis and drawing revision. Evaluate the actual operating point and production tolerances. The platform has not tested the fan, witnessed its balancing/performance process or established that every online table is current.
Specify the system duty
Send air volume, pressure basis, medium/temperature, resistance, supply and installation drawing.
Close the selected evidence
Obtain the current curve and dimension/electrical sheet, resolving HTML/catalogue differences.
Agree sample acceptance
Define performance, sound, balance and interface checks for the actual ordered assembly.
Treat quality certificates and operating claims as documents to review
The about page contains ISO 9001 and CE wording and a linked CE file; the recruitment profile also claims certifications and honours. No certificate issuer/scope/current verification was completed for those claims, so this profile does not label the factory or all products certified. Obtain the issued documents and verify legal holder, exact models, relevant standards, scope and validity with the appropriate source.
The home/about pages use different export-country counts and describe customers, projects and expanded facilities. Those numbers have no independently reviewed basis here and are not used as factory capacity or export-performance evidence. Ask for dated production capability and relevant reference documentation instead of accepting a marketing counter as assurance.
Close OEM, service and commercial commitments in the actual contract
The contact page offers OEM/ODM, generic dispatch periods and warranty/service wording. Obtain the ordered scope, sample approval, tooling/drawing ownership, order quantity, packing and a dated production programme. The website's timing does not establish current stock or the lead time for a modified fan.
Agree inspection, replacement/spares and warranty terms with the actual legal seller and the destination market. Its contact phone differs between pages, so reconfirm the intended business contact; the publicly shown official email is retained only in the private CRM field for a later authorised claim process. No claim email or enquiry has been sent. This platform's role is to organise the sourcing evidence and unresolved decisions, not to certify the supplier or its installed performance.
