Who it's for

Good fit

Why it stands out

The IF14UPS is a no-nonsense wall exhaust fan with a spec sheet to match. Maxx Air's product page lists up to 1,400 CFM from a totally enclosed, single-speed PSC motor (1/5 HP, 1,130 RPM). It also lists 310 W and 2.65 A at 120 V, 27 lb, 20.4 x 20.4 x 12.75 inches, an OSHA-compliant grille and a 1-year limited warranty.

The build suits damp, dusty spaces. The listing describes a galvanized steel housing with pre-drilled mounting holes and rolled edges, a thermally protected motor, and an exterior shutter that opens when the fan runs and closes tightly when it stops. It is made for garages, barns and greenhouses that need heat, odors or moisture pushed outside.

What to know before you buy

  • Opening: the listing gives a 17.25 x 17.25-inch rough-in opening. Frame it before the fan arrives.
  • Wiring: this is the one thing to settle first. Maxx Air lists a 7.5-foot cord with a 3-prong plug, while the listing says the fan has no plug and must be wired into the building's system. If yours needs hardwiring, have an electrician do it.
  • Running cost: 310 W is a lot for 1,400 CFM, and with one speed there is no way to turn it down.
  • Air path: an exhaust fan only moves its rated air when replacement air can get in, so leave a door, window or intake open.

How it compares

  • iLIVING ILG8SF12V 12-inch: iLIVING rates it at 960 CFM on 65 W and 0.6 A. It has less air but a fraction of the power, and it offers variable speed with an optional controller.
  • AC Infinity AIRLIFT T14: the same 14-inch class, rated at 1,513 CFM on 70 W with a published 68 dBA, plus a WiFi environment controller. It is the smarter, more efficient choice.
  • Hessaire 16SF4V75C: a 16-inch shutter fan whose listing claims the same 1,400 CFM, with variable-speed capability. There is no manufacturer spec sheet behind it.

Bottom line

The IF14UPS is a rugged, well-documented small exhaust fan, but not an efficient one. Buy it for durability and simplicity. Choose the iLIVING 12-inch or AC Infinity T14 if you will run it for long hours.

Verdict

Buy the IF14UPS if you want a sturdy, fully documented 14-inch shutter exhaust fan for a garage, barn or greenhouse wall. Skip it if running cost or speed control matters; the iLIVING 12-inch and AC Infinity T14 use a fraction of the power.

Before you buy

Installation and buying checks

Use these questions to verify the exact configuration. Linked facts are cited; unlisted details stay questions.

  1. Mounting and support

    What mounting method and hardware does the exact unit require?

  2. Clearance and handling

    Do the listed physical details leave enough clearance for installation, adjustment, and service?

  3. Electrical match

    Does the documented electrical information match the planned supply? Confirm the installed unit’s nameplate and installation instructions before connecting it.

  4. Airflow at the job

    Is the listed airflow rated at an operating point that matches the job after placement, obstructions, and system resistance are considered?

  5. Location requirements

    Do the documented location and guard details match the conditions and rules at the installation site? Check the manufacturer instructions for the exact configuration.

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.

RoomSizeNominal room volumes / hourNominal pass interval
One-car garage22 × 12 × 9 ft · 2,376 ft³35×1.7 min
Two-car garage22 × 20 × 9 ft · 3,960 ft³21×2.8 min
Workshop40 × 30 × 12 ft · 14,400 ft³5.8×10 min
Warehouse bay100 × 50 × 16 ft · 80,000 ft³1.1×57 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.
