SCT = transformer speed controller

SCE = electronic speed controller

ŋt = maximum total efficiency

tm = maximum air temperature

tu = maximum ambient temperature

to = minimum operating temperature

Lwa 2 = Casing sound power level

Lwa 5 = Sound power level @inlet

Lwa 6 = Sound power level @outlet

The sound power levels are measured according to DIN 45635 part 2 & 38
