When to Choose Shutter-Mounted Exhaust Fans
Shutter-mounted wall fans are a practical solution for many commercial and industrial facilities. They are especially effective for projects with space or budget limitations, or where intermittent ventilation and protection against the elements are needed. More compact and cost-effective than fans with external louvers or hoods, shutter-mounted exhaust fans — also called louvered exhaust fans — provide excellent air movement while conserving energy and lowering cooling costs.
These fans improve indoor air quality by exhausting heat, odors, and fumes, making them popular in factories, warehouses, and utility rooms. Their shutter design prevents rain, snow, wind, and debris from entering, making them a strong alternative to roof-mounted fans in colder climates. Contractors and facility managers also favor shutter exhaust fans when appearance matters, since their compact design minimizes wall projection.
How to Select the Right Shutter Exhaust Fan
When choosing a shutter exhaust fan, keep the following in mind:
- Airflow Needs (CFM): Calculate required cubic feet per minute by multiplying room volume by the air changes per hour (ACH) needed for your application, then divide by 60. NorthStock’s selection ranges from 500 CFM to over 40,000 CFM.
- Mounting Space: Match the fan’s blade diameter to your available wall space, ensuring proper clearance around the installation site. Models are available from 9 inches to 60+ inches in diameter.
- Drive Type:
- Direct drive fans are low-maintenance and best for standard ventilation needs.
- Belt drive fans handle more complex or variable airflow demands.
At NorthStock, we carry shutter-mounted exhaust fans from top manufacturers in a wide range of sizes, speeds, and configurations.
