The PC-31 Portable Evaporative Cooler is an ideal when you’re dealing with sweltering heat, and you need a quick and simple cooling solution. Whether you’re hosting an outdoor event, or trying to make the workspace more comfortable in the warehouse, the PC-31 is an excellent choice.

These portable evaporative coolers work by pumping water from an onboard tank to the top of a filter-like cooling pad. A fan with a capacity of 3,100 CFM (cubic feet per minute) then pulls warm, environmental air over the filter, pushing out air with a cooling effect over 30+ feet. This process can cool an area of up to 950 square feet efficiently.

This portable evaporative cooler has a lightweight design and four lockable caster wheels that make it easy to transport and setup wherever efficient spot cooling is needed. Uses only water and standard 110V power supply to provide 3100 cubic feet per minute of cooling airflow.
