The Marvair® MGA family of vertical exterior wall mount air conditioners are used primarily 

to cool electronic and communication equipment shelters. Due to the high internal heat 

load, these shelters require cooling even when outside temperatures drop below 60°F 

(15°C). Marvair air conditioners have the necessary controls and components for operation 

during these (less than 60°F [15°C) temperatures. All models use the non-ozone depleting 

R-410A refrigerant.

Marvair MGA air conditioners can be equipped with a factory installed economizer. When 

cool and dry, the economizer uses outside air to cool the shelter. The economizer provides 

temperature control, energy cost savings, and increased reliability by decreasing the 

operating hours of the compressor and the condenser fan. Marvair MGA air conditioners 

are problem solvers for a wide range of conditions and applications. To insure proper 

operation and optimum performance, all economizers are non-removable, factory installed 

and tested. In addition, factory and field installed accessories can be used to meet specific 

requirements.
