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

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 exhaust system is an essential facility for fire safety.

The performance listed in the fan's 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-finished fans meet the standard with a full pressure value error not exceeding ±5% under the rated airflow, and the performance selection table represents the performance under standard conditions, regardless of the technology.

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