Industrial-Grade Cooling
Each unit comes equipped with a high-powered axial-flow fan that moves serious air while keeping engine drag low, even at higher speeds. Perfect for warehouses, garages, and outdoor work zones.
Evaporative Cooling
Swamp Coolers
Move a lot of air without installing traditional refrigerated air conditioning. Cool Boss portable swamp coolers combine water, evaporative media and high-volume airflow for shops, warehouses, work areas and other open or well-ventilated spaces.
Direct Evaporative Cooling
Big Airflow. Simple Cooling.
A swamp cooler—also called an evaporative air cooler—uses the natural process of evaporation to cool moving air. Warm air is drawn through water-saturated evaporative media before a fan directs the conditioned airflow into the surrounding area.
Unlike refrigerated air conditioning, the process does not rely on a compressor to cool and recirculate enclosed indoor air. Direct evaporative cooling works with fresh air and adds moisture as it operates.
That makes temperature, relative humidity, ventilation, airflow and placement important when choosing and positioning a swamp cooler.

Swamp Cooler FAQs
How It Works
Water. Airflow. Evaporation.
Direct evaporative cooling uses a straightforward process to condition incoming air.
Wet the Media
Water is distributed across the evaporative media inside the cooler.
Draw In Warm Air
The fan pulls surrounding air through the water-saturated media.
Move Conditioned Air
As water evaporates, it absorbs heat before the fan moves the resulting airflow toward the occupied area.
Conditions Matter.
Evaporative cooling generally has greater cooling potential when the air is hot and dry. As relative humidity increases, the air can accept less additional moisture and cooling potential decreases. A fresh-air path and adequate exhaust are also important when using direct evaporative cooling indoors.

Cooling Powered by Air and Water.
Cool Boss uses evaporative media, water and high-volume airflow to condition incoming air. See the cooling process in action before comparing the individual models.
Cool Boss Features
Designed to Move Air.
Cool Boss offers swamp coolers in multiple sizes and configurations. Exact airflow, controls, lighting, audio, water capacity and other features vary by model.
01 / AIRFLOW
High-Volume Air Movement
Cool Boss models use axial-flow fan designs to move conditioned air toward work areas, occupied zones and other spaces that need additional airflow.
02 / MEDIA
Honeycool™ Evaporative Media
Water is distributed across evaporative media so incoming air can interact with a large wet surface area before leaving the cooler.
03 / SCALE
Multiple Cooler Sizes
Choose among multiple Cool Boss models based on the size of the application, desired airflow, available space and operating conditions.
04 / MOVE
Portable Cooling
Portable models can be repositioned as cooling needs change, helping direct airflow toward different work areas instead of permanently conditioning one location.
Applications
Put the Airflow Where It's Needed.
Portable evaporative cooling can be useful across a range of open and well-ventilated applications.
Garages
Position airflow near service bays and active work areas.
Warehouses
Add portable airflow around occupied zones in large facilities.
Manufacturing
Direct conditioned airflow toward production and assembly areas.
Outdoor Work
Bring additional airflow to covered or open-air work zones where conditions are suitable.
Frequently Asked Questions
Swamp Cooler Questions?
Here's what to know about evaporative cooling, humidity, ventilation and choosing the right Cool Boss for your application.
Is a swamp cooler the same as an evaporative air cooler?
Yes. “Swamp cooler” is a common name for a direct evaporative air cooler. Both describe a system that uses water evaporation and moving air to provide cooling airflow.
How does a swamp cooler work?
A fan draws warm air through water-saturated evaporative media. As some of the water evaporates, it absorbs heat from the air. The fan then moves the resulting airflow toward the surrounding area.
Is a swamp cooler the same as air conditioning?
No. Conventional refrigerated air conditioning typically uses a compressor and refrigerant to condition and recirculate indoor air. A direct evaporative cooler uses water evaporation and airflow, introduces fresh air and adds moisture while operating.
Do swamp coolers work better in dry climates?
Generally, yes. Evaporation can occur more readily when the surrounding air has lower relative humidity. As humidity increases, the amount of additional moisture the air can accept decreases, reducing evaporative cooling potential.
Do swamp coolers need ventilation?
Direct evaporative cooling works best with a supply of fresh air and a path for warmer, moisture-laden air to leave the space. In an enclosed area, adequate ventilation helps prevent humidity from building up and reducing cooling performance.
Do swamp coolers work in very hot weather?
They can, but temperature alone does not determine performance. Relative humidity, ventilation, airflow, water conditions, placement and the specific cooler all affect the amount of evaporative cooling available.
How much can a swamp cooler lower the temperature?
There is no single temperature reduction that applies to every installation. Evaporative cooling potential changes with the incoming air's temperature and relative humidity, along with airflow, placement and equipment configuration.
Can I use a swamp cooler indoors?
Yes, when the application provides adequate fresh-air intake and an exhaust path. Because direct evaporative cooling adds moisture, tightly enclosed spaces without ventilation are generally not a good fit.
What size swamp cooler do I need?
Start with the size and layout of the area, desired airflow, occupied work zones, ventilation and expected temperature and humidity. Then compare those requirements with the airflow and operating specifications of each Cool Boss model.
Which Cool Boss swamp cooler should I choose?
The right model depends on the application. Compare physical size, airflow, water capacity, available electrical service, portability and model-specific features rather than choosing by square footage alone.
