Historical axial fan with unverified model and input
The historical photograph shows a seven-blade axial rotor in a deep square frame, with red and dark lead sections and a visible bare-end portion. It does not show a readable complete manufacturer model or electrical nameplate. The pictured construction does not support the former blower classification.
Y.S.Tech association and manufacturer table
Y.S.Tech FD481238MB, 48V DC and 120x120x38mm are historical merchant associations. Their applicability to the unlabelled photographed item and the currently supplied unit has not been established. The manufacturer, complete model, electrical input, measured frame and mounting remain unverified.
The existing Y.S.Tech official FD1238 series table link is retained for review. The table describes manufacturer catalogue options; the historical photograph does not establish a match to the FD481238MB row. The former 2400 RPM, 107.7 CFM, 5.8 mm-H2O, 41.5 dB(A) and double-ball-bearing claims must not be treated as verified supplied-unit specifications on that basis.
Replacement and connection checks
What must be confirmed? Obtain the complete current label and supplier record, then compare the full model and option, electrical input, measured mounting and clearance, complete harness and termination. The visible lead sections do not establish supplied pinout or functions. Similar frame appearance does not establish equipment compatibility, manufacturer identity or package contents.
Send complete label and connection photos for identification help, or request a wholesale quote. Confirm the supplied unit, condition, package contents and equipment compatibility before ordering.
