The Hessaire 36NS8V370 is a 36-inch guard-mount exhaust fan whose listing claims 9,600 CFM, the highest exhaust airflow in the catalog with a stated figure. It is built for big barns, warehouses and shops, with an IP55 totally enclosed motor and corrosion-resistant guards, per the listing.
What works
- 9,600 CFM on high from a 36-inch blade
What doesn't
- Voltage, wattage, speed control and noise level are not published
- Guard mount with no shutter mentioned, so the opening stays open when the fan is off
Who it's for
Good fit
- Exhausting heat from large barns, warehouses and workshops
- Dusty or damp buildings, given the listing's IP55 totally enclosed motor
- Buyers who want the most exhaust airflow from a single fan
Look elsewhere if
- Small rooms, garages or sheds, where a smaller shutter fan is plenty
- Buyers who need a manufacturer spec sheet with voltage, watts and noise
- Plug-and-play installs, since a 36-inch wall fan needs a framed opening and wiring

See price on AmazonWhy it stands out
When a building needs a lot of hot air out fast, fan size wins, and the 36NS8V370 is the largest-airflow exhaust fan in the catalog with a stated rating. Its listing claims 9,600 CFM from a 36-inch guard-mount fan, well above the 30-inch Hessaire's claimed 6,700 CFM and more than twice the 4,200 CFM iLIVING rates its 24-inch shutter fan at.
The build targets farm and industrial duty. The listing describes a totally enclosed air-over motor rated IP55, copper windings and permanently lubricated ball bearings. It adds corrosion-resistant powder-coated guards, aluminum props, steel and aluminum construction, OSHA-compliant guard spacing, UL 705 certification and full assembly on delivery.
What to know before you buy
- Installation: this is the one to plan carefully. A 36-inch wall fan needs a framed opening, solid mounting and a wired power supply. The listing publishes no voltage or current, so read the motor label and have an electrician size the circuit.
- Shutter: the listing calls it guard-mount and mentions no shutter. Add one if the opening needs to close when the fan is off.
- Air path: 9,600 CFM out means 9,600 CFM in. Open doors, vents or inlets on the opposite side of the building.
- Noise: the listing says "quiet operating" but gives no decibel figure.
How it compares
- Hessaire 30NS8V240: the same build (IP55 motor, UL 705, aluminum props) in a 30-inch size whose listing claims 6,700 CFM. Choose it for a smaller opening.
- iLIVING ILG8SF24V-T: iLIVING rates it at 4,200 CFM, with two speeds, a built-in thermostat and a shutter. It is the manufacturer-documented pick for a garage-sized space.
- TPI CE 30-DV: a 30-inch venturi-mounted exhaust fan with a 1/4 HP two-speed 120 Volt motor and pull-chain switch, per its listing. It suits buyers who want two speeds and can add an external shutter.
Bottom line
The 36NS8V370 is the fan for big buildings that need big exhaust. Plan the opening, wiring and intake air, and it will move more air than any other exhaust fan listed here.
Verdict
Buy the 36NS8V370 if you need the most exhaust airflow in a single wall fan for a barn, warehouse or large shop and can plan the opening and wiring. Skip it for smaller spaces, or if you need published electrical data before you buy; the 30-inch Hessaire or a 24-inch shutter fan is easier to install.
Questions people ask
- How much air does the Hessaire 36NS8V370 move?
- The listing claims 9,600 CFM.

Put 9,600 CFM in context
The Hessaire 36NS8V370 36-Inch Exhaust Fan has a listed airflow of 9,600 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 | 242× | 15 s |
| Two-car garage | 22 × 20 × 9 ft · 3,960 ft³ | 145× | 25 s |
| Workshop | 40 × 30 × 12 ft · 14,400 ft³ | 40× | 1.5 min |
| Warehouse bay | 100 × 50 × 16 ft · 80,000 ft³ | 7.2× | 8.3 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.
