[Ambient temperature for use]

The ambient temperature range to ensure you reach the ultimate pressure is 10-23℃. The permissible ambient temperature is 10-32℃ for air cooling type and 10-40℃ for water cooling type. The maximum temperature for the cooling water which ensures the ultimate pressure is 30℃ and the allowable temperature range for cooling water is 10-35℃.

[Corresponding gases]

Some types of gas to be evacuated may damage the pump. Contact Osaka Vacuum for a list of applicable gas types.
