The Maxx Air IF14UPS is a 14-inch, one-speed wall exhaust fan with 1,400 CFM listed by the current manufacturer page.
What works
- The exact IF14UPS plain-carton alias is listed on the current manufacturer page
- Current specifications list 1,400 CFM, 120V, 2.65A, 310W, a 7.5-foot cord, and automatic shutter
What doesn't
- The page requires 4.5 square feet of net-free intake area
- A replacement-motor page lists different motor data and should not be blended with the assembled-fan specification
Who it's for
Good fit
- A fixed 14-inch wall-exhaust installation with a documented 17.25-inch square rough opening and adequate intake
- Ordinary heat, humidity, or stale-air removal where its 120V plug-in configuration fits the site
Look elsewhere if
- Hazardous fumes or chemicals
- A system without a planned replacement-air path
The current page confirms the plain-carton IF14UPS
Maxx Air’s 14-inch heavy-duty exhaust-fan page lists IF14UPS as the plain-carton alias. For the assembled fan, it lists up to 1,400 CFM, a one-speed totally enclosed PSC motor, 1/5 HP, 120V/60 Hz, 2.65A, 310W, and 1,130 RPM. It also lists a 27-pound unit, 20.4 × 20.4 × 12.75-inch H × W × D dimensions, a 7.5-foot three-prong cord, an automatic shutter, and a one-year limited warranty.
The wall opening is part of the purchase decision: Maxx Air specifies 17.25 × 17.25 inches and 4.5 square feet of net-free intake area. Plan the intake and exterior discharge before treating the 1,400-CFM figure as an installed result. A blocked louver, restricted intake, or poor air path can reduce delivered flow.
Do not blend the replacement motor with the whole fan
Maxx Air also offers a replacement motor compatible with IF14 and IF14UPS. Its listed motor ratings differ from the assembled-fan page. That may reflect a replacement or later component configuration; it does not revise the whole-fan specifications above. Use the assembled IF14UPS page and the actual unit nameplate for selection, then use a replacement part only after confirming compatibility.
The manufacturer says this fan is not intended for hazardous fumes or chemicals. For ordinary ventilation, compare it with other industrial exhaust fans using opening, intake, electrical, and location details. The CFM calculator can examine a stated room-flow assumption, but it cannot replace the intake and installation requirements for the real wall system.
Verdict
Choose the IF14UPS for a properly planned small wall-exhaust opening when its documented opening, intake, and electrical details fit. Use the assembled-fan page for selection, not the specifications of a replacement component.

Put 1,400 CFM in context
The Maxx Air IF14UPS 14-Inch Exhaust Fan has a listed airflow of 1,400 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 | 35× | 1.7 min |
| Two-car garage | 22 × 20 × 9 ft · 3,960 ft³ | 21× | 2.8 min |
| Workshop | 40 × 30 × 12 ft · 14,400 ft³ | 5.8× | 10 min |
| Warehouse bay | 100 × 50 × 16 ft · 80,000 ft³ | 1.1× | 57 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.
