Altitude
   Operating: Sea level to 10,000 ft
MTBF
   Calculated using MIL standard 217F

*As altitude increases, air density decreases and, therefore, the cooling effect of a particular number of CFM decreases. Different limits can be achieved by trading among altitude, temperature, performance, and airflow. Contact Mercury for more information.
