The Cool Boss Portable Evaporative Air Coolers Line from BendPak includes seven energy-efficient models designed to cost-effectively keep workers cool and safe from heat-related injuries. All Cool Boss air coolers are equipped with oversized pumps and fan motors, as well as automatic low-level shutdown valves to prevent pump burnout. The Cool Boss lineup consists of two series. The four COOLBREEZE portable air coolers are compact and feature automatic swing louvers to provide complete control over where the chilled air goes. The larger COOLBLAST commercial-grade models have fixed louvers for precise directional cooling. All units have a soft-touch LED control panel.
