Dry Transformer Cross Flow Fan
GFDD / GFD Series · Forced-Air Cooling · Top / Side Discharge
Cross-flow cooling fans for forced-air cooling of cast-resin dry-type transformers. The tangential airflow is directed into the winding air ducts to improve heat dissipation under AF duty.
Designed for practical power-asset applications
Dry transformer cross-flow fans provide directed forced-air cooling for cast-resin transformer windings under AF duty. Match the existing fan model, mounting dimensions, voltage, frequency and discharge direction before ordering.
What we confirm before quotation
We coordinate the technical and commercial details with the appropriate manufacturing partner before confirming price, lead time and documents.
Supply format
Single replacement units, spare-part batches or planned maintenance quantities, subject to model, quantity and availability confirmation.
Typical document package
Datasheet, dimensional or wiring information, inspection records and export documents are provided where applicable to the selected configuration.
Please include in your inquiry

Features & Benefits
Directed Winding Cooling
Tangential airflow is delivered into winding and core air passages at the required discharge angle for effective heat dissipation.
AF Duty Support
Designed for transformer forced-air cooling arrangements; any capacity uplift remains subject to the transformer manufacturer’s thermal design.
Top or Side Discharge
Specify top-blowing or side-blowing orientation to suit the transformer enclosure and cable-clearance layout.
Export-Oriented Build
Corrosion-resistant aluminium-alloy or stainless-steel housing options, safety mesh and project-matched mounting details.
Typical Applications
Forced-air cooling for indoor dry-type distribution transformers operating under AF duty.
Replacement of an existing GFDD / GFD cross-flow fan where model, dimensions and electrical supply are confirmed.
Additional cooling for dry-type transformers in substations, industrial plants and data-center electrical rooms.
Frequently Asked Questions
What information is needed for fan selection?
Send the existing fan nameplate or model, transformer kVA rating, supply voltage/frequency, mounting dimensions and required top/side discharge direction.
Can this fan increase transformer capacity?
Cross-flow fans support forced-air (AF) cooling, but any uprating must follow the transformer manufacturer’s thermal design and nameplate limits.
Can you supply 60 Hz or non-standard voltage versions?
Yes. Confirm the required voltage, frequency and phase at inquiry stage; availability depends on the selected model and motor configuration.
