Are swamp coolers better than industrial fans?

If you’re trying to cool down a room or a large open space, two options usually come up: swamp coolers and industrial fans. Both can be great options for supplementing air conditioning—or replacing it altogether. Yet swamp coolers and fans each have their own benefits and drawbacks depending on your environment, cooling needs, and facility layout. 

To decide between a swamp cooler and fan, you’ll need to consider your goals and environment. For a lot of small and large businesses, the best fit is a swamp cooler. When compared to fans, swamp coolers provide more effective cooling for large areas.  

What’s the difference between a swamp cooler and a fan? 

Swamp coolers 

Swamp coolers, also known as evaporative coolers or portable coolers, reduce air temperature by passing hot air through water-saturated evaporative media. The result: cool, fresh airflow delivered back into the environment. 

Fans 

Industrial fans use rotating blades to move hot air around. They don’t lower the air temperature—they just recirculate existing air, which can create a breeze but doesn’t result in actual cooling. 

Swamp coolers vs. fans comparison 

Both swamp coolers and fans come in a range of sizes to fit specialized use cases. To decide if swamp coolers or fans are better for your business, consider your unique goals and needs. 

Cooling performance: Swamp coolers protect your workers from the heat 

Hot working conditions are not only uncomfortable— they’re dangerous. Protecting employees from heat stress is critical in industrial settings. Swamp coolers actively cool the air, reducing ambient temperatures by as much as 30°F in dry climates. This makes them ideal for: 

• Manufacturing plants
• Automotive shops
• Warehouses
• Airplane hangers
• Gyms and athletic training facilities 

Meanwhile, fans just move the air around, they don’t cool it.  

Ventilation: Tie 

Both swamp coolers and fans improve air circulation, but they do so differently: 

• Swamp coolers draw in fresh air, pass it through evaporative media, and cool it before distributing it through the space.
• Fans are best for ventilation only, particularly in enclosed areas with limited external airflow. 

If your space has open bay doors or vents, a swamp cooler improves both cooling and ventilation. If you’re simply looking to move air in a sealed room, a fan may be more efficient. 

Swamp coolers are the top choice for commercial spaces which have access to outside air, such as: 

• Drum manufacturing facilities
• Welding shops
• Heavy machine shops   

Portability: Tie 

Swamp coolers and fans come in a range of sizes and designs. Most evap coolers can be moved around on wheels, giving them the name portable coolers. Some industrial fans might have to be mounted to the walls or ceiling, but you can also find fans that move on wheels. 

Both evaporative coolers and fans need to be plugged into a power source. Swamp coolers also need water, and you can add it by filling up the water reservoir or connecting the cooler to a water source. 

Swamp coolers deliver targeted cooling, whenever and wherever you need it. That’s why car racing pits and bike shops use swamp coolers to fit their tight spaces. 

Environment: It depends 

Swamp coolers and fans are ideal for different environments.  

Swamp coolers are better if: 

• You operate in a hot, dry climate
• Your facility has open air access (bay doors, vents)
• You need to lower air temperatures, not just improve comfort 

Fans are better if: 

• You’re in a mild or humid climate
• Your facility is fully enclosed
• You only need to circulate air, not cool it 

Swamp coolers are life-savers for manufacturing plants in hot, dry environments. 

So… Are Swamp Coolers Better Than Fans? 

It depends on your needs: 

When to Choose a Swamp Cooler:

• You need to actively cool a space (not just move air)
• Your environment is hot, dry, and has good airflow
• You want a cost-effective, energy-efficient cooling solution 

 When to Choose a Fan: 

• You need to improve airflow in a mild or humid space
• Your space is enclosed or lacks fresh air access
• You need basic ventilation without temperature reduction
