Re-environmental protection The welding fume purifier designed to control the fine metal particles that are currently suspended in the air and is harmful to the human body during welding can be installed on the ground, on the ground or on the movable cart. Different types of movable arm tubes and exhaust fans can be selected, which can be called high-efficiency dust collecting equipment during long-time large-scale electric welding operations. The use of a flexible arm that is freely movable, inhaling and capturing smoke at the source of the source, protects the health of the worker and increases work efficiency. The mobile welding fume purifier has the option of removing the odor from the active carbon fiber filter. Three filters are used to capture from mist to smoke. It is equipped with wheels and moving handles for easy movement. The welding fume purifier is mainly used for the treatment of odors in laser jet printers, cutting plotters and plastic processing. Small in size and high in dust removal efficiency, it can be used anytime, anywhere.
