The package documents 0–2500 RPM default, 0–4000 RPM automatic, and fixed 4000 RPM modes. S5M007 uses the 4000 RPM mode and recorded a 3894.4 RPM final-window average. This sample is stored separately from the 2500 RPM MasterFan A120 (F009).
Rated CFM, mmH₂O, and dB(A) use each manufacturer's own test conditions. They help identify product positioning but are not used as a cross-brand acoustic-performance ranking. TK Lab fields contain measured data only.
