01 / Ownership & scope

The relationship behind the guide.

FANFACTORYCHINA.COM is a China HVLS fan industry directory and procurement guide with a commercial connection to the RTFANS inquiry route. RTFANS is a registered brand owned by KOOL AIR INTERNATION DEVELOPMENT CO., LTD. Buyers should take this relationship into account when reading featured placement and project recommendations.

RTFANS appears alongside other supplier profiles under the same public-source framework. Those profiles support supplier research and comparison. The directory is not an independent certification body or an exhaustive register of every HVLS fan manufacturer.

Commercial route
RTFANS has a directory profile and the current direct project inquiry route reflects the site's commercial relationship.
Listed supplier
An external supplier included for procurement research. Inclusion alone does not establish a commercial partnership, factory audit or approval of its products.
Paid listing
A commercial service for directory exposure, subject to the listing rules below. A supplier profile's presence alone should not be read as evidence that the supplier has paid.

02 / Ranking & evaluation

How to read comparisons.

Supplier listing numbers are reference numbers from the supplied directory. They do not represent a ranking of manufacturing capability, product quality or suitability for your project. All records are presented as directory references.

The published evaluation framework sets out six procurement dimensions and their weights. These weights describe the comparison framework; they are not individual supplier scores or proof that every supplier has completed an assessment.

Manufacturing capability and capacity
20%
Product performance and reliability
20%
Export experience and delivery
20%
Certifications and compliance
15%
Technical support and OEM capability
15%
Procurement value
10%

Search visibility and domain authority indicators describe a website's online presence. Read the DA definition and source disclosure before using those figures in a supplier comparison.

03 / DA & data sources

What the DA number tells you.

What is Domain Authority?

DA stands for Domain Authority. In this directory, DA is the domain authority indicator reported by Ubersuggest in its Domain Overview. It is a third-party SEO reference metric that estimates a website's relative search visibility from its domain and link data. It is not a score issued by Google or a direct Google ranking factor.

A higher Ubersuggest DA generally indicates stronger predicted search visibility within that tool's model. The scale should be used for relative comparison only: a ten-point increase does not have the same meaning at every level, and a score of 60 does not mean a website has twice the traffic, authority or business capability of a website scoring 30.

Where the numbers on this site come from

The DA badges in our brand directory display values collected from Ubersuggest's Domain Overview during directory research and then recorded in the site's research dataset. They are stored reference values rather than live lookups, so a later Ubersuggest lookup may show a different value after its index or model is updated.

Published value
The recorded DA value associated with the official website in a brand or supplier record.
Source
Ubersuggest Domain Overview, using the official domain associated with the brand or supplier record.
Measurement status
Values are research snapshots recorded in the dataset, not a live API value or a permanent score.
Source evidence
Ubersuggest is the source of the displayed DA values. The value can change when Ubersuggest refreshes its backlink index or scoring model.

How to compare scores fairly

For a fresh comparison, check each official domain in Ubersuggest with the same domain scope and over the same reporting period. A root domain, subdomain or individual page may produce different results, so the directory uses the official domain associated with each profile. Values from different SEO tools use different datasets and models and should not be mixed into one comparison.

Scores can change when a provider updates its link index or model, even if a supplier's products and factory remain unchanged. A low score may reflect a new or less visible website, while a high score may reflect an established link profile. Neither establishes manufacturing capacity, product quality, certification validity, financial reliability or delivery performance. DA is not one of the six procurement evaluation dimensions published above.

To suggest a DA correction, send the official domain, provider, exact metric name, lookup date and a supporting report or screenshot to info@hvlsfans.cn.

05 / Sources & verification

Read the evidence with the claim.

Profiles draw on the supplied supplier directory, official domains, public product information and supplier-provided materials. Source notes, review dates and confidence statements describe the information available for that profile. A review date does not mean a factory visit, independent product test or certificate authentication has taken place.

Supplier-provided
Information supplied by a brand or supplier. Check the current version, scope and supporting documents before relying on a claim.
Public product information
Statements recorded from official websites or public product materials. Publication by a supplier does not mean the claim has been independently tested.
Requires supplier confirmation
A field that needs a direct answer or supporting document from the supplier before it can inform an order.
Not publicly disclosed
The profile does not have sufficient public information for this field. This does not establish whether a supplier has or lacks the capability.
Pending document review
Technical files or supporting evidence still need review. Read this status alongside the source and review date on the profile.

Technical claims and certifications

Fan diameter, airflow, coverage, noise and energy figures may use different test conditions. Compare the exact model, mounting height, measurement method and operating point before treating figures as equivalent.

Certification marks or certificate names recorded from a supplier's materials are supplier claims unless the profile states a specific verification basis. Request the current certificate or test report, check the named manufacturer and covered model, and confirm its relevance to your destination market.

Prices, availability and external websites

Published price ranges are planning references. Configuration, quantity, currency, shipping terms, destination and quotation date can change the final price. Official website links help you check a source; their presence does not guarantee the site's current content, product availability or the supplier's performance.

06 / Inquiry routing

Where your project brief goes.

In the current site phase, valid requests submitted through the site's procurement forms follow the RTFANS inquiry route, including requests started after viewing an external supplier profile. This form is not a broadcast request to every listed supplier and does not send your brief to the external supplier whose page you were reading.

The brief includes the contact and project details you choose to submit, such as your name, work email, company, building type, estimated quantity, preferred fan size, destination, timeline and project notes. These details provide context for an RTFANS project response.

KOOL AIR INTERNATION DEVELOPMENT CO., LTD

sales@hvlsfans.cn

Submitting an inquiry starts a sales conversation. Product selection, price, delivery scope and contractual terms still need to be agreed in a written quotation or contract. To contact an external supplier, use its own official contact channel.

07 / Before you order

Confirm the details for your project.

A directory profile is a starting point for a supplier conversation. Before committing to an order, confirm the following against current documents and the final quotation.

  • Supplier identity. Check the legal seller, factory location, manufacturing scope and the company named on your quotation and contract.
  • Building and product fit. Confirm floor area, clear height, mounting structure, obstructions, voltage, controls and operating conditions for the proposed model.
  • Technical evidence. Request model-specific specifications, relevant test reports, certification scope and installation requirements.
  • Commercial and service scope. Agree on price, quantity, lead time, Incoterms, installation responsibility, warranty and spare parts support.

08 / Corrections & updates

Help keep supplier records current.

Company details, domains, product lines and certifications can change after a profile's review date. Read the date and evidence notes on the individual profile when assessing how current its information may be.

To report an error or submit an update, email info@hvlsfans.cn with the profile URL, the specific claim to change, the proposed correction and a supporting source or document. For ownership or official domain changes, include evidence connecting the brand, company and website.

Submitted evidence is reviewed before a correction is published. A listing may be updated or paused when its source, contact details or published claims can no longer be verified.
