18 Inches That Clears a Workshop Fast

The VEVOR 18 in shutter exhaust fan handles 3,051 CFM at up to 7.7 m/s, making it a dependable choice for workshops, auto bays, and stables that need repeated air exchange. Noise is capped around 68 dB, so it runs loud enough to notice but not to shout over.

Which Space Is This Size For?

Fits workshops, garages, and stables up to roughly 3,800 sq ft. For bigger barns, the 20 or 24 inch fans are the better investment.

Powerful 3051 CFM Ventilation for Garages, Attics, and Workshops

Keep hot, humid, and stale air moving with the VEVOR 18 inch shutter exhaust fan. Rated at 3051 CFM with air speeds up to 7.7 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 just 79 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 space does a 3051 CFM exhaust fan handle?

A: At roughly 8 air changes per hour it covers about 2,800 sq ft at 8 ft ceilings, and it empties a 1,200 cu ft space (about 150 sq ft) in around 24 seconds at full speed. Open barns and greenhouses working to 3 or 4 air changes per hour can be several times larger.

Q: What is the difference between an exhaust fan and a ventilation fan?

A: Both terms cover fans that move air, but exhaust fan is the more precise label when the goal is removing air from a space. This unit exhausts air outside, so fresh air is drawn in through an open door, window, or inlet vent on the opposite side of the room.

Q: Can it be installed outside in rain?

A: Yes, exterior wall mounting is expected for this shutter exhaust fan. The automatic louvers close when the fan stops and keep rain and debris out of the housing, and the steel body is built for damp conditions. Prolonged standing water or full roof exposure is not recommended.

Q: How loud is the 18 in model in a shop?

A: Noise is rated at 68 dB or lower at full speed, and the stepless controller lets you run well below that for background ventilation. It is a working-fan noise level rather than a bedroom fan level, so it suits shops, garages, and barns better than living spaces.

Q: How many CFM do I need for a garage exhaust fan?

A: Use 8 air changes per hour as a starting point, which is cubic feet x 8 / 60. A 5,000 cu ft shop with 10 ft ceilings needs about 667 CFM and a 3,000 cu ft three-car garage about 400 CFM, so this 3051 CFM fan can handle demanding work like welding or paint fumes while still being turned down.

Q: Does it require an electrician or ductwork?

A: Neither. Frame and cut the wall opening to suit the 21.3 x 21.3 in housing, secure the fan with the supplied expansion bolts, anchors, and screws, and plug it into a standard 120V outlet. There is no duct to run.

Q: Should I leave an inlet open while the fan runs?

A: Yes. With no inlet path the fan fights a vacuum and real airflow drops well below the rated 3051 CFM. Leaving a door, window, or inlet louver open at the far side of the room gives the strongest cross-flow and the fastest clearing.

Q: What is the shipping and return policy?

A: Orders ship free from a US warehouse, typically within 1-3 business days, and arrive 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.
