drum fans are made of all-metal construction,the high-velocity metal fan boasts outstanding durability built to withstand the dust and debris of busy workshops and garages
High energy efficiency: The super mobile fan has overcome the technical challenges of low speed and large air volume, and adopts a 220V permanent magnet DC brushless motor, completely resolving the contradiction between air circulation and high energy consumption. The stepless speed control controller makes it possible to precisely control the air volume.
