品特点：该产品采用多羽式离心风轮及引进美国LAU的先进技术精心设计制作而成。它具有风量大、风压较高、噪音低、性能稳定等特点，是目前空调及工业送风的主要设备之一。 应用范围： 1. 厨房排烟必备抽气设备。 2.工业厂房换气排风主要设备。 3.消防排烟主要设备。 4.宾馆酒楼、地下室通风主要设备。 5、商场、影剧院、也可用做空调送新风。 注：表格中的风量和风压是在一个测验转速下的最大和最高取值数，并非对应比值，表格中的该风机箱体由框架，面板，消声/隔音材料组成。框架采用铝合金型材或镀锌钢板折边成型，面板中间层填有聚氨脂发泡，玻璃纤维等，具有良好的消声/隔音性能。表面经过喷涂处理，外表美观，根据安装位置不同，可分为A型电机外置和 B 型电机内置两种，电机外置式为消防通风用，电机内置为通风用。 此风机广泛使用于宾馆，体育馆，学校，酒楼，影剧院，礼堂，高级民用住宅和工矿企业等消防通风的场合。输送空气和其它不自然，对人体无害，无腐蚀性气体，气体内不允许有粘性物质，所含的尘埃硬质颗粒物不大于150mg/m3，作通风换气时进入气温度不得超过 80℃，A型系列作消防用时，烟气温度在 280℃情况下能连续运行三十分钟以上。 This fan case is made up of the frame, the panel, the noise elimination / the sound insulation materials. The frame is made from aluminum alloy material or zinc-plated steel with folded edges, and the middle layer of the panel is filled with polyurethane foam and reinforced glass so as to achieve a better noise elimination /sound insulation performance. The surface is treated with spray painting, and the appearance is beautiful. Based on the installation site, the fans can be divided into two kinds: Model A with electrical motor fixed outside and Model B with the motor fixed inside. Model A is for the use of fire control ventilation while Model B is for the use of ventilation ,This fan is used as fire control ventilation extensively in the hotel, the gymnasium, the school, the saloon bar, the theatre, the auditorium, and high-graded civil houses and industrial and mining enterprises. It is used to transmit air and other unnatural, non-corrosive gases that are harmless to the human body. No adhesive materials are allowed in the gases, and the hard dust particles contained shall not be greater than 150mg/m3. As ventilation and air exchange, the incoming air temperature shall not exceed 80℃. When the Model A series are used for the fire control purpose, they can continue to runmore than 30 minutes under the condition of smoke temperature at 280℃. 风速是在未接管时(流量最大时)的取值数。设计选型考虑实际情况。
