4. 安装方便：低噪音风箱机采用全金属可拆卸框架和内帖隔热吸声板，可直接与风管连接或墙 壁安装，安装形式可采用垂直或水平式。很大程度地节省了占地面积。可现场拆装，安置灵活，很大程度地节省了占地面积。
The low noise centrifugal fan is a new type of force source compared with the common centrifugal fan. It has the advantages of large air volume, low noise, saving electricity and convenient disassembly in the field.
1. large air volume: low noise centrifugal fan equipped with multi-directional inlet and outlet, with wide selection of air volume and wind pressure. Meet a variety of needs.
2. low noise: This is an important difference between low noise centrifugal fan and ordinary centrifugal fan. Low noise centrifugal fan adopts low noise centrifugal fan, which has the characteristics of low noise, small vibration and low noise, thus reducing the noise to the lowest.
3. high efficiency: the low noise centrifugal fan is developed by multi-objective optimization design with advanced CAD software. After testing, the fan efficiency is higher than 80%, and the efficiency curve is flat. It is beneficial to energy saving.
4. installation is convenient: the low noise air box machine adopts all metal detachable frame and inner insulated sound absorption board, which can be connected directly with the wind pipe or wall installation, and the installation form can be used vertically or horizontally. The area is saved to a large extent. It can be disassembled and installed at the scene, and the placement is flexible. It saves the floor area to a large extent.
