Ranger CB-30L (110V Model)

Portable Evaporative Air Cooler

To keep shops and workplace areas cool, the CB-30 110 Volt model uses ordinary tapwater combined with forced air to reduce air temperatures by as much as 26°F. Best of all, it’s a super-effective cooling device that costs about a dollar per day to operate. One large 30” diameter fan operates at three selectable speeds, and a thick cooling pad ensures even water distribution and reliable heat absorption. Automatic swinglouvers oscillate side-to-side and help circulate cold air more efficiently, providing a larger cooling area than traditional evaporative air coolers.

The CB‐30 Cool Boss™ swamp cooler, sometimes called an evaporative air cooler, provides a low‐cost, environmentally‐friendly way to keep shops cool and workplace areas comfortable, even during the hottest summer months.
