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EXdl或EXdI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。

(B)F4-72(C式)型玻璃钢离心通风机是叶轮采用水冷座或油冷座经角带与电机传动。其好处是减少腐蚀电机、减速、降低电机负荷等作用，从而增加风机使用寿命。

BF4-72 glass fiber reinforced plastic explosion-proof centrifugal fan accordingto the conditions of use the configuration EXdl or EXdll class A, B grade Exmade of isolated motor can deliver containing methane, ethane, propanestyrene,toluene, and second,toluene,carbon monoxide, acetic acidkerosene, gasoline, furans and other flammable,explosive, volatile gases.ltsperformance parameters and mounting dimensions are consistent with F4-72FRP centrifugal fan.

(B)by the F4-72 (C type) FRP centrifugal fan impeller water-cooled seator oil cooled by the angle with the motor drive. lts benefit is to reduce thecorrosion of motor, reducer, reducing the role of motor load, therebyincreasing fan life.
