For heatstroke prevention and factory heat management! Even in large, spacious areas, we achieve comfort with cool air and airflow. The "Duct Cooler" is a commercial large cooling fan that creates a massive evaporation phenomenon with four evaporative filters and delivers it with a large airflow of three-phase 200V. A powerful airflow of 20m/s sweeps through hot work sites. We achieve comfort with cool air and airflow, even in large, spacious areas. Unlike spot coolers, the duct cooler does not emit heat, so there are no worries about humidity. It can be adopted in metal, plating, and film factories. 【Features】 ■ Intense airflow ■ Extremely cool ■ Air direction can be freely changed with duct modifications (optional) ■ Heat management ensures labor safety and health in factories and work sites ■ After outdoor installation, cool air can be directed to targeted areas via ducts.
