For applications that require static pressure, commercial and industrial supply fans bring fresh air in from the outside to help you avoid a negative pressure environment, reduce the risk of mold and mildew, and eliminate odors or potentially harmful vapors. These intake fans are at work in hospitals and labs, chemical plants, paint booths, barns, manufacturing facilities, storage rooms, greenhouses, gyms, and other facilities to keep air moving through the building to ensure employee comfort and appropriate conditions for your equipment and products. 

At NorthStock, we carry a wide range of ventilation solutions, including industrial intake fans from Triangle Fans. Available in a variety of models and sizes, these supply fans are trusted for long-lasting performance in applications all over the world. Search by part number or browse our selection:

About Industrial Supply Fans

Since 1948, Triangle Fans has been committed to creating a fan for every need, and that's apparent in their wide selection of options, including commercial air intake fans. The RV series of belt drive industrial supply fans are designed for long-lasting performance in gyms, factories, and warehouses. They feature automatic belt tensioning to reduce maintenance and extend the lifespan of the belt and motor, an open drip-proof motor, rolled venturi for improved airflow, and all welded construction with a durable polyester powder coated finish. Blade diameters range from 24" to 48".

Because these orders cannot be canceled or returned, please confirm the intake fan is the right one for your application before placing your order. If you have any questions or concerns, contact us in advance. 

For heavy-duty applications, the RVI series features heavy-gauge galvanized housing for enhanced corrosion resistance and are commonly used in greenhouses, factories, distribution centers, and more. They're available in a range of sizes from 24" to 60" blade diameter with optional two-speed, 115V single-phase, and 1/3 and 1/2 HP motors. Optional accessories include the field-installed rain hood and OSHA screen guard. 

Choosing the right supply fan is essential for creating a safe, comfortable environment and replacing stale or potentially hazardous air with fresh outside air. You need to consider your airflow demands, the room occupancy, environmental conditions (such as hazardous locations that may require a specialized explosion-proof solution), energy efficiency, installation location, and the acceptable noise level. Triangle commercial supply fans are known for reliability and efficiency, and with a range of sizes and CFM ratings, you can find the right wall intake fan for your application.
