4—72型离心通风机可作为一般工厂及大型建筑物的室内通风换气用，输送空气和其他不自然的、对人体无害的、对钢材无腐蚀性的气体。B4—72型风机可输送易燃易挥发性气体，但温度不得超过80℃。
B4—72型风机的性能与选用件及地基尺寸与4—72型一致，可按其样本选择。该风机结构基本与4—72型相同，№2.8～6A采用B35型带法兰与底脚的电动机，№6～12C、D电动机选用该表中与Y系列对应的YB系列，安装型式为B3。
№2.8～6出厂时均做成1种型式，使用单位根据要求再安装成所需要的位置，订货时不需注明，№2.8出风口位置调整范围0°～225°，间隔是45°。№3.2～6出风口位置调整范围0°～225°，间隔是22.5°。№8～12出风口位置调整范围0°～225°，间隔是45°。№16、20出风口位置制成固定的三种0°、90°、180°，不能调整，订货时须注明。
风机的传动方式有A、B、C、D四种。
4—72型风机中，№2.8～6采用A式传动，№8～12采用C、D式传动，№16～20采用B传动。
