A fan powered box is a type of HVAC system component that uses an electric fan to draw in outside air and distribute it through the building. This type of system is often used in commercial buildings, as it provides an efficient and cost-effective way to maintain comfortable temperatures. The fan powered box works by drawing in outside air, which is then heated or cooled as needed and distributed throughout the building. This type of system is typically more efficient than traditional HVAC systems, as it does not require a large amount of energy to operate. Additionally, the fan powered box is often quieter than other HVAC systems, making it a great choice for buildings that require a quiet environment. This type of system is also beneficial for buildings that have high ceilings, as the fan powered box can effectively distribute air throughout the entire building. Overall, the fan powered box is an efficient and cost-effective way to maintain comfortable temperatures in commercial buildings.
