Put 647 CFM in context

The HG Power 10-Inch Shutter Exhaust Fan has a listed airflow of 647 cubic feet per minute. The table compares this rated volume with example room volumes. It does not measure fresh-air exchange, air speed at your body, or room coverage.

Room	Size	Nominal room volumes / hour	Nominal pass interval
One-car garage	22 × 12 × 9 ft · 2,376 ft³	16×	3.7 min
Two-car garage	22 × 20 × 9 ft · 3,960 ft³	9.8×	6.1 min
Workshop	40 × 30 × 12 ft · 14,400 ft³	2.7×	22 min
Warehouse bay	100 × 50 × 16 ft · 80,000 ft³	0.5×	124 min

A circulation fan does not by itself replace indoor air. Exhaust airflow depends on a makeup-air path and system resistance. Use installed outdoor airflow for ventilation calculations.

Formula: airflow × 60 ÷ room volume. CDC explains the ventilation form of this equation; here the input is a catalog rating, so the result is a volume comparison.
