Much like the rest of the Cool Boss lineup, the COOLBLAST Series is capable of dropping ambient temperatures by as much as 26°F, and it can do so without relying on chemicals. That being said, the COOLBLAST Series isn't just about cooling; it's a feature-rich solution for your convenience. Let time never limit your work. COOLBLAST units feature 4000 lumens of LED floodlights to brighten up your night, and every COOLBLAST model boasts a Bluetooth® audio player for music to accompany your cool, refreshing air.
