The Ranger Products Cool‐Boss evaporative air cooler, No. CB-30L, provides an environmentally‐friendly way to keep shops cool and workplace areas comfortable even during the hot summer months. The CB‐30L uses tap‐water combined with forced air to reduce air temperatures by as much as 26 degrees F. The CB‐30L features a micro‐computer programmed control panel with LCD display and comes with a convenient remote control. Built‐in timer allows the unit to be programmed to turn on or off at pre-selected times. A large 30" diameter fan operates at three selectable speeds and a thick cooling pad ensures even water distribution and reliable heat absorption.
