Fire-resistant high-temperature exhaust fans are suitable for high-rise buildings, underground structures, tunnels, drying rooms, and other ventilation or smoke exhaust applications. They can operate under high temperatures of up to 280℃.

Operates continuously 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 performance table is within the efficiency range, divided into five performance operating points by air volume. The performance table should be referred to when selecting.

The factory-certified fans meet the specifications with an air volume deviation of no more than ±5% under full pressure, and the performance selection table represents the performance under standard conditions, regardless of technology.

Performance of documents or order requirements is based on standard condition.
