An Engineered Air Make Up Air Unit is a device designed to bring fresh air into a building or other enclosed space. It is typically used in industrial and commercial settings, such as factories, warehouses, and restaurants, to ensure that the air inside the space is clean and safe to breathe. The unit works by drawing in fresh air from outside and then filtering it before it is released into the space. This helps to reduce the amount of pollutants, dust, and other airborne particles that can accumulate in the air. Additionally, the unit can also be used to regulate the temperature and humidity levels inside the space, providing a comfortable and healthy environment for those inside. The unit is typically powered by electricity and is relatively easy to install and maintain.
