Building Fire Smoke Exhaust Fan

In building a fire smoke exhaust fan, the Axial flow mechanism, the gas flows parallel to the axis of the fan and has the characteristics of large air volume and low noise. The insulation class is an F-class motor, equipped with a motor cooling system to avoid direct contact between the airflow and the motor, and reduce the damage of harmful gases and high-temperature gases to the motor.
Excellent performance: The fan test meets the requirements of the GBJ45-82 fire protection standard. The fan is designed and manufactured, the motor is built in, and an independent motor cooling system is set. 300℃ can run continuously for more than 120 minutes, 100℃ can run continuously for 22 hours without failure, and the performance is higher than the standard.
According to the different requirements of users, single-speed, two-speed, and multi-speed types can be used to achieve the purpose of one machine for dual purposes (that is, common ventilation and exhaust air and high-temperature smoke exhaust during a fire); the shape of the blade is divided into the axial flow and mixed flow. Mode. , It can be made into roof smoke exhaust type and noise reduction type.
The fan efficiency is greater than 85%, and some models are greater than 90%, and the efficiency curve is flat, which is conducive to energy conservation and environmental protection, and promotes green and low carbon;
It is easy to install and has a smaller footprint than a centrifugal fan, and can be directly connected to the air duct or installed on the wall. The installation form can be linear and horizontal floor installation and hoisting, and the floor installation needs to be equipped with a damping system; high-strength spring damping pads and rubber damping pads are hoisted with spring damping hangers and fixed with screw rods. Equipped with a shock absorption system to weaken the vibration of the machine itself, reduce the external transmission of vibration force, prevent the introduction of vibration force, and ensure the normal operation of the fan.
