Quick Answer

Description
At a Glance
The largest size in the range, this 24 in shutter exhaust fan moves 7030 CFM and clears a 1,200 cu ft space (about 150 sq ft at 8 ft ceilings) in roughly 10 seconds. It suits barns, large workshops, greenhouses, and equipment rooms, the automatic louvers close down the opening between runs, and the stepless controller tames a 185 W motor that would otherwise be all or nothing.
24 Inches, 7,030 CFM: One Fan for the Whole Barn
The VEVOR 24 in shutter exhaust fan is the biggest wall-mount unit in this series, shifting 7,030 CFM for barns, warehouses, and large workshops. It runs at 1,400 r/min with noise up to 73 dB — noticeable, but proportionate to the volume of air it moves.
Which Space Is This Size For?
Designed for barns, warehouses, and big workshops up to roughly 8,800 sq ft. For smaller buildings, the 14–20 inch models deliver more practical value.
Powerful 7030 CFM Ventilation for Large Garages, Barns, and Workshops
Keep hot, humid, and stale air moving with the VEVOR 24 inch shutter exhaust fan. Rated at 7030 CFM with air speeds up to 10 m/s, this wall mount ventilation fan quickly clears heat, moisture, smoke, floating dirt, and odors from garages, attics, barns, greenhouses, and workshops. The variable speed controller lets you match airflow to the job, from a gentle breeze to full exhaust.
Automatic Louvers and Rain Protection
The automatic louvers open when the fan is running and close when it stops, blocking rain, dust, and small debris between uses. Combined with a sturdy, rust-resistant steel housing, this attic exhaust fan is built for damp environments where plastic fans fail.
Variable Speed Control for Every Space
The included stepless controller puts airflow at your fingertips. Whether you need continuous air exchange in a greenhouse or high-volume cooling in a workshop, the 1400 r/min AC motor delivers stable, low-noise performance on 185 W.
Built to Last in Tough Environments
The steel housing provides high rigidity and resists deformation, handling damp conditions and rain better than plastic. It is a dependable choice for attic exhaust, garage cooling, barn ventilation, and greenhouse airflow projects.

Frequently Asked Questions
Q: What size building does a 7030 CFM exhaust fan suit?
A: At about 8 air changes per hour it covers roughly 6,500 sq ft at 8 ft ceilings, and it clears a 1,200 cu ft space (about 150 sq ft) in around 10 seconds at full speed. Barns, greenhouses, and open shops that only need 3 to 4 air changes per hour can be considerably larger.
Q: What is the difference between an exhaust fan and a ventilation fan?
A: The terms describe the same equipment from different angles. Ventilation fan is the general label for any air-moving fan, while exhaust fan specifies the task of pushing stale, hot, or contaminated air outside. This model exhausts air out, so fresh air enters through open doors, windows, or an inlet vent.
Q: Can this fan be installed outdoors in rain?
A: Yes, exterior wall mounting is normal for this shutter exhaust fan. The automatic louvers close when the fan stops and shield the housing from rain and debris, and the steel body is built for damp conditions, though it should not sit in standing water.
Q: How loud is the 24 in model?
A: Noise is rated at 73 dB or lower at full power, which is a working-fan level suited to barns, workshops, and greenhouses. The stepless controller lets you run far quieter for continuous ventilation and only open it fully when you need maximum air exchange.
Q: How many CFM do I need for a garage exhaust fan?
A: Use 8 air changes per hour, or room cubic feet x 8 / 60. A 20,000 cu ft barn with 12 ft ceilings works out to about 2,667 CFM, while a 3,000 cu ft garage needs about 400 CFM, so this 7030 CFM fan covers the largest spaces and still throttles down for everyday use.
Q: Does it run on standard household power?
A: Yes. The 185 W motor runs on 120V / 60Hz and plugs into a normal outlet, so no special circuit or hardwiring is required once the wall opening is framed.
Q: Why leave an inlet open while the fan runs?
A: An exhaust fan removes air, and a sealed building creates a vacuum that drops real airflow below the rated 7030 CFM. Leaving a door, window, or inlet vent open on the far side of the space keeps cross-flow strong and clearing fast.
Q: What is the shipping and return policy?
A: Orders ship free from a US warehouse, typically within 1-3 business days, with delivery in 2-5 business days to the 48 contiguous states. The fan includes 30-day returns plus manufacturer warranty, and the PDF installation and operation guide is linked on this page.
