Put 2,796 CFM in context
The Schaefer VAF3000A 12-Inch Exhaust Fan has a listed airflow of 2,796 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 | 71× | 51 s |
| Two-car garage | 22 × 20 × 9 ft · 3,960 ft³ | 42× | 1.4 min |
| Workshop | 40 × 30 × 12 ft · 14,400 ft³ | 12× | 5.2 min |
| Warehouse bay | 100 × 50 × 16 ft · 80,000 ft³ | 2.1× | 29 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.
