What factors influence the price of cooling fans for dry-type transformers?

• Suitable for Purchasing Dry-Type Transformers with Cross-CurrentCooling Fans, customers for GFDD cooling fans and transformer fan spare parts.
• Prices are typically based on the model, length, impeller diameter, voltage, quantity, installation orientation, and delivery time.
• Before requesting a quote, please have the old fan’s nameplate, external dimensions, mounting hole locations, and on-site photos ready to help reduce the time needed to verify the model.

Purchasing cooling fans for dry-type transformers may seem simple, but factors such as length, impeller diameter, airflow direction, mounting hole positions, and power supply requirements can all influence the selection process. If the buyer simply states that they need a transformer fan, it is difficult for suppliers to provide an accurate quote. Yinnotongda can assist in confirming specifications based on GFDD series cooling fan documentation and on-site photos, whether for new project installations, replacement of existing fans, or the procurement of spare parts.

GFDD top-blow cross-flow cooling fans are commonly used for heat dissipation in dry-type transformers. GFDD470-150 refers to a single-phase 220V, top-blow cross-flow fan for dry-type transformers with a total length of 470 mm and an impeller diameter of 150 mm. Different numerical designations indicate different sizes and configurations; please specify the complete model number when requesting a quote.

If the nameplate on the old fan shows markings such as GFDD470-110 or GFDD470-150, please send a photo of it along with your inquiry. Do not simply estimate based on length, as the mounting hole positions, impeller diameter, and wiring configuration can also affect the replacement.

GFDD Cooling Fan Procurement Documentation Checklist

Fan prices and lead times are closely related to the dimensions. We recommend measuring the total length, width, height, mounting hole spacing, airflow direction, and power cord location, and taking photos of the fan installed at the bottom or side of the transformer.

If the old fan has already been removed, lay it flat and take a panoramic photo, then photograph the nameplate, wiring terminals, mounting holes, and impeller location. When placing a bulk order, please specify how many fans are required for each transformer and whether they should be oriented identically on the left and right sides.
