A good ventilation system is essential for good indoor air quality, and it's especially important in commercial and industrial settings where people may be working around chemicals, gases, and other particulates and contaminants. The right system helps prevent condensation and mold and lowers the risk of respiratory issues among your employees.

When choosing your ventilation system, you have to consider whether you want to expel the indoor air, as you would with a roof fan, or if you need to exchange it with outdoor air, which can be done with energy recovery ventilators. Maybe you simply need to keep air circulating, and a ceiling fan would do the trick. To make it easier, every product listing comes with a complete list of features, photos, manuals, and catalogs, as well as competitive pricing and lead times. Use the information to determine whether the product you've selected will be able to manage your situation.

Whether you're looking for roof ventilation, garage ventilation, or any other type of ventilation fan, NorthStock, Inc. has you covered. We're the go-to supplier for all your HVAC needs, and as such, we carry thousands of commercial and industrial fans. Browse our thorough selection below.

About Our

Systems & Industrial Fans


Our more than 300 different air circulators help with climate control and keep your equipment operating at its best. Meanwhile, air curtains are ideal for exterior entrances or any doorway where you want to separate one space from another. The downward-blowing air creates a barrier to help you maintain your temperature inside while blocking pests, outdoor air, and outdoor contaminants—all without creating a physical barrier that impedes your workers.

Energy recovery ventilators get rid of stale indoor air and bring in fresh air from outside, tempering it as it enters to ensure your comfort, even in the middle of winter or summer. Wall fans also exchange the air, but without the temperature control. Odor control blowers are ideal for medical cannabis producers or other operations where smell can become an issue. Utility blowers are great for general exhaust needs, and they can be used indoors or outdoors.

We also carry ceiling exhaust fans, ceiling fans, duct fans, and roof fans from the brands you know and trust. We're confident we can offer the right solution to your industrial and commercial ventilation needs.

Our longtime relationships with suppliers and years of experience in the industry allow us to offer some of the most competitive pricing in the country—with no surprises. The price is clearly listed, and we outline any accessories or special considerations required for the ventilation system to operate properly. We also list optional accessories you may like to have to suit your unique circumstances. We offer free shipping to the lower 48 states, with expedited shipping often available if the situation is urgent.
