This Burnham Commercial assembly unit is a combination of a protective covering and an air circulation device. The protective covering, also known as a canopy, is designed to shield the internal components of the system from external elements such as dust, debris, and weather conditions. The air circulation device, commonly referred to as a blower, is responsible for maintaining airflow within the system. It ensures that heat is evenly distributed throughout the system and prevents overheating by pushing out excess heat. This assembly unit is specifically designed for use in commercial heating systems and has been manufactured using high-quality materials to ensure durability and longevity.
