D: Features
There is a positioning joint between the first and the second sections of the external supporting arm structure. When the extraction arm is pulled down, it can be positioned to prevent the extraction arm from falling. There is a movable joint between the second and the third sections of the external supporting arm structure, it can adjust and fix the angle of the extraction arm appropriately. The hose reducer and the flexible hose also have the function of adjustment, guaranteeing convenient placement of the extraction arm hood close to the source of pollution and capturing different gases and dust avoiding their expansion in the room. This unit can be easily retracted and positioned after not in use, to facilitate the cleaning of the workplace. Additionally, the base of the extraction hose can be 180° rotation and the extraction hood has a damper device to control the airflow by switching the knob.
