Why Do Manufacturers of Dry-Type Transformer Fans Consider Mounting Hole Locations When Providing Quotes?

• Suitable for purchasing dry-type transformersCooling Fans, customers of GFDD fans and cross-flow fans.
• The mounting hole locations will determine whether an old fan can be replaced directly; you cannot simply place an order based on length alone.
• Before requesting a quote, we recommend providing the nameplate, hole spacing, airflow direction, cable exit, and photos of the installation site.

Quotes for dry-type transformer fans often depend on the mounting hole locations, as customers typically prefer to install replacement fans in the same location as the old ones and do not want to drill new holes or reroute wiring on-site. For GFDD cross-flow cooling fans, in addition to the model and length, it is necessary to confirm the mounting hole spacing, impeller diameter, airflow direction, and power supply specifications. Innotongda can assist in confirming the specifications based on photos provided by the customer.

Confirmation of Mounting Hole Positions and Model Suffixes for Dry-Type Transformer Fans

GFDD470-150 refers to a cross-flow fan for top-blow dry-type transformers with a single-phase 220V power supply, a total length of 470 mm, and an impeller diameter of 150 mm. The dimensions vary depending on the model number, so prices cannot be determined based on appearance alone.

The mounting hole locations are critical information for replacing old components. If the hole spacing does not match, it may be necessary to modify the bracket or drill new holes on-site, which could affect installation time and the power outage schedule.

Purchasing Specifications for Dry-Type Transformer Fan Mounting Holes

Please provide the fan nameplate, total length, width, height, mounting hole spacing, airflow direction, cable outlet, power supply information, and the number of transformers used for each unit.

On-site photos should include the fan as a whole, the mounting bracket, the wiring location, and the fan’s position on the transformer. For bulk purchases, you should also verify that all fans are of the same specification.

Request for Quotation for Replacement of Existing Parts for Dry-Type Transformer Fan Mounting Holes

If the nameplate on an old fan is blurry, you can use the overall length, hole spacing, impeller diameter, and airflow direction to help identify it. Taking a photo of just a small section isn’t enough; it’s best to take both a full-view shot and close-ups.

If repairs are urgently needed, please specify the downtime and your desired shipping date. We will prioritize verifying the key dimensions that could affect the replacement.

Discussion on Manufacturer Quotes for Dry-Type Transformer Fan Mounting Holes

Manufacturers' quotes are based on the model, dimensions, quantity, delivery time, and documentation requirements. If you need English-language documentation or an international sales quote, we recommend specifying this during your initial contact.

Innotongda will provide a price quote based on the confirmed model and on-site information; it does not apply the specifications of a single model directly to all GFDD fans.

Differences Between Project-Specific and Spare Parts for Dry-Type Transformer Fan Mounting Holes

Project specifications focus more on drawings, order quantities, technical documentation, and delivery schedules, while spare part replacements focus more on old models, wiring, installation dimensions, and on-site compatibility. When requesting a quote, clearly state the intended use so that suppliers can more quickly identify the key points in the documentation.

If you need both spare parts and project products, we recommend listing the quantities, delivery dates, and documentation requirements separately. We will confirm these based on their specific uses and will not apply a single model or set of specifications to all procurement requests.

Confirmation of Information and Pricing

To ensure that the quote more closely matches your actual procurement needs, we recommend that you clearly specify the product name, full model number, quantity, intended location of use, whether the product is a replacement for an existing item, whether English documentation is required, and your expected delivery date when making initial contact. If the product is to be used as part of a project, you may also provide drawings, technical specifications, and packaging and shipping requirements.

Innotongda will provide documentation and quotations based on the models, configurations, and technical requirements confirmed by both parties. This will reduce the need for repeated verification and minimize the risk of purchasing incompatible products.

Procurement Contacts and Responses to Inquiries

If the buyer already has photos of the used parts, they can simply send the images and quantities; if this is for a new project, they can first send the drawings, technical specifications, or a product list. We will first confirm the product details and then respond with the relevant materials, pricing, and any additional information required.
