Our high performance Rotary-Type Evaporative Cooler is a self-contained unit with a cylindrical evaporative media constructed from layers of corrugated bronze screening. Continuously rotating in a stainless steel water reservoir, the media is wet and washed while air is drawn through the media. This process draws off minute films of water for efficient evaporation. The evaporative efficiency is minimum 85% at 20F wet bulb depression. The rugged constructions of Westaire CFR Units comply with the United States Military Specifications (MIL-OC-22948C) and have a minimum life expectancy of twenty years.

Capacity for standard units range from 2,000 to 30,000 CFM. For larger capacities consult with the factory.
