This is a 24v 0.10A DC cooling fan. Dimensions are 40mm x 40mm x 10 mm. Sufficient for use in 3D printing, operating speed is 500 RPM. Two terminal cable length is 9 centimeters (9cm). Connector is already fitted and product is out-of-the-box ready for installation.
Equipped to properly cool your 3D printer’s extruder assembly, this extruder fan is compatible with the MakerBot Replicator 2 and MakerBot Replicator 2X. Also Flashforge, CTC, and other 3D printer types.
