Product Overview
The portable fan duct surface uses electrostatic spraying technology, the impeller is made of aluminum alloy, with a galvanized mesh cover, a glass fiber reinforced nylon material injection molded handle, and an aluminum shell motor structure. It is lightweight, easy to move, performs excellently, has strong suction power, is safe and durable, and has a reasonable structure. It is a professional fan for shipbuilding, machinery, and underground engineering, and can be used with retractable ducts. It is widely used in basements, tunnels, municipal pipeline projects, mechanical shipbuilding projects, mining ventilation equipment, fire smoke exhaust, and other harsh air environments, as well as for discharging harmful gases, smoke dust, and hot air generated during welding operations. It is also used for exhausting waste gas in confined narrow spaces.
