Explosion-proof) HTFC Fireproof Cabinet-type Dual-purpose Centrifugal Fan Unit Detailed Introduction: The HTFC fire ventilation low-noise cabinet-type centrifugal fan is a dual-purpose, high-efficiency, low-noise cabinet-type centrifugal fan successfully developed by our company. It features significant advantages such as low noise, excellent high-temperature resistance, novel and compact structure, minimal vibration, light weight, and convenient installation and maintenance. It is widely used in hotels, restaurants, auditoriums, theaters, basements, industrial and mining enterprises, office buildings, and other occasions requiring fire smoke exhaust, kitchen fume extraction, and ventilation (suitable for both ceiling-mounted and floor-standing installations). It can be used for both air supply and exhaust and has been widely adopted across the country, receiving high praise from users. It is currently an ideal product for high-rise building fire smoke exhaust and ventilation.

This product series is divided into two types: Type A and Type B. Type A has the motor installed outside the cabinet and, after high-temperature testing, can operate continuously for over 40 minutes under high-temperature conditions with smoke temperatures exceeding 280°C, achieving the purpose of fire smoke exhaust. Equipped with a dual-speed motor, it can be used for ventilation at low speed and fire smoke exhaust at high speed, serving dual purposes. Type B has the motor installed inside the cabinet and is generally used for air supply and exhaust ventilation.

V. GXF Ducted Mixed Flow Fan Application: Utilizing the mixed flow meridional acceleration design method, it adopts a drum-shaped or straight air duct and a twisted airfoil blade structure. It combines the high-pressure coefficient of centrifugal fans with the large flow coefficient of axial fans, featuring low noise, energy savings, and a compact structure. It can be installed either horizontally or vertically and is widely used in industrial and civil building air supply and exhaust systems.
