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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
