Number of fans per row: 5 — Digit 1-9; total fans = fan rows x this digit.
-
E
Fan diameter: 80 — Ø800 mm
-
G
Coil tube rows (2nd dimensional letter): D — 5 tube rows
-
H
Fin spacing: 1 — 2.1 mm
-
I
Generation code: B — generation B
-
J
Fan data (fan motor code): 01 — fan motor code; supply/poles vary with diameter
