Product Specifications

Review the technical data used for replacement matching, procurement comparison and engineering approval.

Historical listing photographs: The gallery retains existing photographs from this listing's historical image set. They are not proof of current shipping stock. The complete archived original photographs remain in store records outside the current gallery.

The retained historical whole labelled angled rear shows a readable nameplate marked Delta EFC1248DF -5W33, 48V DC 0.33A. Red, black, blue and yellow fan leads, a pale multi-position connector and black jumper loop are visible; pin assignments are unverified.

Confirm the full supplied model and ordering option, electrical label, measured dimensions, condition, harness, complete connector and pinout before ordering. Historical photographs do not verify those offered-unit details.

FAQ

Common checks for replacement cooling fan sourcing.

Can you help match an old fan?

Yes. Send photos of the fan label, connector and equipment so we can check model, voltage, frame size and wiring.

Can I use a different brand as a replacement?

Often yes, but only after confirming frame size, electrical rating, airflow requirement, bearing type, connector and wire sequence.

What information is needed for a bulk quote?

Send part number, quantity, target lead time, connector or cable requirements and shipping destination.
