Does anyone know what G(Y)4-73-11 No.14D represents? Is it universal?

G stands for blower. Y stands for the exhaust fan, 4-73-11 is the model of the fan, 14 is the serial number of the fan, and D indicates that it is connected using a coupling. This is a relatively common type of fan. Every fan manufacturer has them, and the drawings are in national standards. But in order to sell accessories, each manufacturer modifies the dimensions of certain parts. Hehe, bad, right?

Adding to what was said above: Chassis Nos. 8 to 12 are designed as a single unit and cannot be separated. Cases No. 14 to 16 are designed as two-part types. Cases No. 18～28 are designed as three-part types
