Product Specifications

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

The listing used MS510 as its model and EC as an electrical value. The photographed physical nameplate instead reads NMB-MAT BM5020-04W-B29, 12V DC and 0.09A. A model identifier and an electrical voltage are different fields; EC is not substituted for the directly printed 12V value. The supplied model remains unverified rather than silently selecting the photographed version.

The round intake, curved housing and lateral discharge show a centrifugal blower. Existing 50x50x20mm dimensions remain legacy reference information, not a measurement from the image. Confirm the actual assembly envelope, outlet, mounting points and complete label. Seller graphics include a SUNON corner addition as well as shop text; these are not the physical manufacturer plate. Lead colours do not prove pinout or signal functions, and the image does not prove projector compatibility, current inventory or untouched-camera provenance. Earlier processing is unknown.

Send label and connector photos for identification help. For quantities, request a wholesale quote.

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.
