Environmental
Temperature
   Operating: 0°C to 40°C
   Storage: -40°C to +85°C
Altitude
   Operating: 10,000 ft
   Storage: 30,000 ft
*CFM: 20 (at sea level)
Humidity: 10-90% non-condensing
Vibration: 0.003g2/Hz, based on 20-2000 Hz, 1 hr/axis
Shock: z-axis: 20g; x-, y-axes: 32g; 11 ms half-sine;  3-positive and 3-negative on each axis
Rugged options: Consult factory.

*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 temperature, altitude, frequency, and airflow. Consult factory for additional information.
