Industrial ventilation refers to the system used in factories and other workplaces to control air quality and temperature. It helps remove harmful pollutants, dust, and excess heat from the air, ensuring a safer and more comfortable environment for workers. These systems can be natural or mechanical. Natural ventilation relies on windows and vents to allow fresh air in, while mechanical ventilation uses fans and ducts to circulate air. Proper ventilation design is crucial for maintaining health standards and improving productivity in industrial settings.
