一、风机概述
SEF/WEXD/WEX/DWEX/WEF/WSP/BDWEX/FDWEX边墙风机采用先进的前掠型叶片、低噪音的外转子或内转子风机专用电机直联传动，方形外壳设计可以方便地安装在混凝土墙、砖墙或轻钢压型墙板上，方形防雨罩结构牢固，外形美观。具有噪声低、风量大、运行可靠、性能参数范围广、安装简便等特点，广泛应用于厂矿企业车间和民用、商用建筑工程的边墙壁式通风换气。根据输送介质的要求，可制成防腐、防爆型。
SEF/WEXD/WEX/DWEX/WEF/WSP/BDWEX/FDWEX边墙风机一般用于边墙壁式排风，配设45°防雨罩（或特殊制造成60°）和防虫网（夜间可防止昆虫循灯光飞入车间）。可按需要制成边墙送风机型号为DWSP(WSP)，配设90°防雨罩(防风、雨、尘)和防虫网（夜间可防止昆虫循灯光飞入车间）。
附件选配:重力式止回风阀（可确保车间在风机不开时保持与室外隔绝），订货时注明。
