A fan powered is a type of ventilation system that uses fans to circulate air throughout a building or space. This type of system is typically used in commercial or industrial buildings, but can also be used in residential settings. Fan powered systems are typically more efficient than traditional HVAC systems, as they use less energy to move air throughout the space. Fan powered systems are also often quieter than traditional HVAC systems, as the fans are typically smaller and quieter than traditional HVAC systems. Additionally, fan powered systems are often more flexible than traditional HVAC systems, as they can be adjusted to provide the desired air flow and temperature in different areas of the building. Fan powered systems are also often more cost-effective than traditional HVAC systems, as they require less maintenance and are more energy efficient. Finally, fan powered systems are often more environmentally friendly than traditional HVAC systems, as they use less energy and produce fewer emissions.
