Continuous operation for over 30 minutes, and remains undamaged after 20 hours of continuous operation at a medium temperature of 100℃ under ideal fire protection conditions. This smoke exhaust system is an essential facility.

The performance listed in the fan's performance table is within the efficiency range, divided into five performance operating points according to airflow. Refer to the performance table for selection.

Factory-finished fans meet the quality standards with an air volume error of no more than ±5% under rated conditions. The performance selection table indicates performance at standard conditions, regardless of technology.

All file or order requirement performances are based on the standard condition.
