The FCA 5-20 is designed to assist in climate control in a small to large facility and serve multiple uses. You can circulate, refresh and cool the air in a room by placing it on a stand with wheels, a wall mount, or you can mount it in a window or other ventilation opening. The evaporative cooling design also makes it possible to use the units in a semi closed or open environment with optimal cooling effect. The unit is operated by a hand held remote and can be connected to an external water source for extended run-time and convenience. We have purchased one of these for store use to keep things cooler from now through the summer.
