Designed for large garages, workshops, barns, and greenhouses, this 7030 CFM wall-mount fan refreshes a typical 100-150 sq ft space in about 20 seconds.

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.

Quality vent, quiet operation, compact size.
It comes bare wire, you’ll need a plug end or terminal box.
Moves enough air to keep the upper story from heating up where it used to be consistently hotter than outdoors, sometimes now I need to shut the other fan off to be comfortable when the night or morning air is too cool.
I plugged it in to a drop light extension cord for now, with a plan to add thermostatic control and hardwire it.

Extremely strong and quiet
One strong fan! This fan is everything that it was described to be and extremely quiet. Love it so much I plan to buy more for other projects.

Easy install
The fan was very easy to install. I used the front packing cardboard as a template, and powered the unit through an outlet with a thermostatic switch plugged into it.

Reasonably easy to install
Installed it in my metal building. Keeps out the hot air that builds up near the ceiling. Can tell a large difference between before and after installation.

Great replacement for older mushroom cap roof vent
So after the third AC induction motor died in one of the Master Flow Roof Mount Attic Fan (3 over 12yrs), I thought I’d retro-fit this in place. Just unbolted it from the shutter and used the fan and grill. Works great and uses almost half the watts. The old setup had 1500 CFM and was always present (noisy) when running, with this (up to 4800 CFM) I run at speed 7 and barely hear it.
