HVLS stands for High Volume Low Speed. These are large-diameter fans (usually 7 feet or more) that move massive volumes of air at low rotational speeds, ideal for cooling large spaces efficiently.
HVLS fans improve air circulation, which reduces the load on HVAC systems. They help maintain consistent temperatures, allowing you to raise the thermostat setting while still keeping spaces comfortable—resulting in up to 30% energy savings.
Yes! HVLS fans complement HVAC systems by distributing cooled air more evenly across large spaces. This leads to more consistent temperatures and improved overall efficiency.
Our fans can be installed on ceilings, trusses, or special mounts. We provide expert installation guidance and support to ensure safe and optimal placement for maximum airflow.
