F4-72型玻璃钢离心通风机
F4-72型玻璃钢离心通风机是参照金属4-72型通风机性能参数而采用玻璃纤维和树脂模压而成。该系列风机可输送含酸碱成分及化学成分的腐蚀性气体。所输送气体不允许含有粘性物质、所含粉尘及硬质颗粒≤150mg/m、气体温度≤60℃相对湿度≤100%。该系列风机具有强度高、重量轻、不易老化、耐腐蚀性能良好、噪音低、运转平稳等特点，是一种较为理想的通用型防腐风机。该系列风机广泛应用于化工、电镀、氧化发电厂、化验室、线路板、环保设备等含有腐蚀性气体的场所。
BF4-72型玻璃钢防爆离心通风机是根据客户的使用条件配置EXdI或EXdII类A、B等级防爆隔离型电机制作而成。可输送含有甲烷、乙烷、丙烷、苯乙烯、甲苯、二甲苯、一氧化碳、醋酸、煤油、汽油、呋喃等易燃易爆挥发性气体。其性能参数和安装尺寸与F4-72型玻璃钢离心通风机一致。

The F4-72 type FRP centrifugal fan
The F4-72 type FRP centrifugal fan is made of glass fiber and resin molding with reference to the performance parameters of the metal 4-72 type fan.The series of fans can transport corrosive gases containing acid and alkali components and chemical components. The gas is not allowed to contain viscous substances,dust and hard particles is less than or equal to 150mg/m’,the gas temperature are less than 60, the relative humidity is less than100%. This series of fans is characterized by high strength, light weight, no ageing,good corrosion resistance,low noise and smooth operation. It is an ideal universal anti-corrosion blower. This series of fans are widely used in chemical,electroplating. Oxidation, power plants,laboratory,circuit board, environmental protection equipment and other sites containing corrosive gases.
BF4-72typeglass FRPexplosion-proof centrifugal fan is made from Exdlor Exdll class Aand B grade explosion-proofisolation motor according to the customer's use conditions.lt can transportinflammable and explosive volatile gases includingmethane,ethane,propane styrene,toluene,xylene,carbon monoxide,acetic acid,kerosene,gasoline and furan. The performance parameters and installation dimensions are consistent with the F4-72 type FRP centrifugal fan.
