Produce twice as much cool air as standard mobile evaporative air coolers. Also known as swamp coolers, use these air coolers wherever air conditioning is impractical. They take in water, which soaks into pads. When air is blown through the wet pads, the evaporation produces cool air.

Replacement pads are sold separately.

Mobile Evaporative Air Coolers

Nema 5-15

Also known as swamp coolers, use these air coolers wherever air conditioning is impractical. They take in water, which soaks into pads. When air is blown through the wet pads, the evaporation produces cool air. These air coolers have a direct-drive motor, which has fewer moving parts than belt-drive motors for less maintenance. All have a NEMA 5-15 plug, which is a standard three-prong plug.

Hazardous Location Mobile Evaporative Air Coolers

These air coolers are rated for environments where hazardous material is present. Also known as swamp coolers, they take in water, which soaks into pads. When air is blown through the wet pads, the evaporation produces cool air. Coolers have leads for hardwiring or use with a hazardous location electrical plug. Replacement pads are sold separately.

Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.
