This application also claims priority to U.S. Provisional Application No. 63/539,536, titled “Leaf Blower Fan,” filed on September 20, 2023, the entirety of which is incorporated herein by reference. The present disclosure generally relates to an air moving device, more specifically to an air moving device equipped with a multi-fan system, and even more specifically to a leaf blower equipped with a multi-fan system. Air movement devices are used for various purposes. Examples include drying, cooling, debris transport, ventilation, thrust generation, and hovering. Air movement devices may not be able to provide the function of controlling airflow. A leaf blower is a type of air movement device that may not be able to provide the function of controlling airflow, and as a result, the ideal operation of the leaf blower may not be realized. The following summary provides a general overview of various aspects of the present disclosure. This summary is not an inclusive description of all aspects of the present disclosure and should not be understood as identifying key or important elements. In one aspect, the present disclosure provides an air moving device configured to propel air. The air moving device may comprise a housing having a first chamber, a second chamber adjacent to the first chamber, an intake end, an exhaust end, and an exhaust region. The air moving device may also have a plurality of independently controllable fan systems, wherein the fan systems may include a first fan system configured to propel a first airflow having a first flow characteristic through the first chamber, and a second fan system configured to propel a second airflow having a second flow characteristic through the second chamber.
