Product Details

The Axial Smoke Exhaust Fan features a specialized impeller constructed with meridional-acceleration tapered twisted blades welded onto the hub. The air inlet incorporates a streamlined trumpet-shaped silencer integrated seamlessly into the casing. Equipped with internal guide vanes, the unit delivers superior airflow distribution and stable static pressure performance, representing an advanced hybrid fan technology bridging axial and centrifugal blower designs.Powered by a high-temperature resistant motor, the fan can operate continuously for over 60 minutes at 280℃ during fire smoke emergency duty, and run non-stop for over 20 hours at 100℃ without mechanical or electrical degradation, making it ideal for dual-duty application (general ventilation and emergency smoke exhaust). Single-speed units are available in 14 standard impeller diameters ranging from 250 to 1,000 mm.This fan series is widely deployed in high-rise buildings, industrial and mining enterprises, hotels, restaurants, museums, gymnasiums, and underground basements. It is exceptionally well-suited for inline duct pressurization, fresh air supply, smoke extraction, and general ventilation across high-rise and commercial architecture.
