宠物垫丝网除沫器安装摘要:Flexible fan blades which decamber with increasing speed of the fan are mounted to a casting. The hub and spider arms are defined by the casting. The spider arms are thick and aerodynamically shaped to reduce the tendency of the fan to stall. The arms support the blade along its entire length to prevent lateral vibrations.
