   Minimum airflow/slot: 38 CFM at sea level
Temperature
  Operating: 0°C to 35°C
Altitude
   Operating: Sea level to 10,000 ft*
MTBF
   Calculated using MIL Standard 217F
   (Consult the factory for Ground Benign 30C Mil 217F data)

*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.
