Operates continuously for over 30 minutes and remains undamaged after 20 hours of continuous operation at a medium temperature of 100℃ under ideal fire prevention 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 by air volume. Refer to the performance table for selection.

Factory-assembled fans are qualified under the rated air volume with total pressure deviation not exceeding ±5%, the performance selection table is the performance under standard conditions, regardless of technology.

All performance specifications for documents or order requirements are based on standard conditions.
