1、 Hood type smoke exhaust fan

Hood type smoke exhaust fan is a device that integrates smoke exhaust hood and fan, suitable for scenarios where smoke and exhaust gas need to be pumped outdoors. The hood type smoke exhaust fan has a simple installation and maintenance process and is suitable for various industrial and commercial buildings. At the same time, the hood type smoke exhaust fan has certain noise and air resistance, and relevant inspections and maintenance need to be paid attention to.

2、 Pipeline smoke exhaust fan

The ducted smoke exhaust fan leads smoke or exhaust gas out of the room through a series of pipes. It is suitable for scenarios that require the removal of top smoke and high-temperature exhaust gases, including commercial centers, hospitals, schools, and hotels. The ducted smoke exhaust fan has excellent performance and efficient smoke exhaust effect, but the installation and maintenance costs of the pipeline are high, requiring regular inspection and cleaning.

3、 Mixed flow smoke exhaust fan

A mixed flow smoke exhaust fan is a device that converts exhaust gas or smoke into heat energy by using an absorption smoke exhaust hood, mixed flow fan, and rotating radiator. This device is suitable for scenarios that require the elimination of small indoor smoke and exhaust gases, such as commercial centers, small factories, and workshops. The mixed flow smoke exhaust fan has advantages such as small volume and low power consumption, but its smoke exhaust efficiency is relatively low and needs to be selected according to the situation.
