HVLS stands for High Volume, Low Speed, which refers to a type of fan designed to move large volumes of air at a low rotational speed. The main difference between wall-mounted HVLS fans and ceiling-mounted HVLS fans lies in their installation location, airflow direction, and the size of the area they can effectively cover. Wall HVLS fans are mounted on walls and provide horizontal airflow, whereas ceiling HVLS fans are suspended from the ceiling, generating a vertical airflow pattern to cool and circulate air in large spaces.
These wall fans are not your typical wall fan, the main difference lying in the Revolutions Per Minute (RPM) of the fan. To be classified as an HVLS fan, the RPM should be below 1000 RPM and would generally sit between 50-200 RPM.
Installation Location
Wall HVLS Fans
These fans are installed on the walls, typically at a height that allows them to blow air horizontally across the floor or other specific areas. They are commonly used in settings where ceiling space is limited or when a specific airflow pattern is desired. There are however different mounting brackets available for use which does make them reasonably versatile, mounting from an I-beam column for example.
Ceiling HVLS Fans
These fans are installed on the ceiling, typically suspended from the ceiling structure. They are designed to circulate air in large spaces from overhead, creating a downward flow that helps cool the entire area. Ceiling HVLS fans are often utilized in warehouses, manufacturing facilities, gymnasiums, and other large open spaces where maximum coverage is desired.
Airflow Direction
Wall HVLS Fans
Wall fans are primarily designed to create a horizontal airflow pattern, moving air parallel to the floor or specific areas. They can be positioned to blow air in a specific direction or to cover a targeted region. The horizontal airflow creates a good cooling effect; however, the area can be less than ceiling fans.
Ceiling HVLS Fans
Ceiling fans are designed to generate a vertical or downward airflow pattern. They move large volumes of air from the ceiling towards the floor, creating a gentle breeze throughout the space. The downward airflow helps with cooling, air circulation, and destratification; reducing temperature differences between the ceiling and floor.
Space Coverage
Wall HVLS Fans
Due to their horizontal airflow pattern, wall-mounted HVLS fans are effective in localized or targeted areas. They are suitable for applications where a specific zone requires air movement or where ceiling-mounted fans are impractical.
Ceiling HVLS Fans
Ceiling HVLS Fans: Ceiling-mounted HVLS fans are designed to cover larger areas and provide overall air circulation in expansive spaces. They are capable of moving air effectively across vast floor areas, ensuring consistent airflow throughout the entire space.
In summary, when it comes to choosing the perfect HVLS fan for your space, it's important to consider the installation location, airflow direction, and the size of the area you want to cover. Wall HVLS fans offer a unique solution by being mounted on walls, allowing for a strategic placement that maximizes airflow. With their horizontal airflow pattern, these fans effectively cool and circulate air, creating a comfortable environment in any room. On the other hand, ceiling HVLS fans provide a different approach. Suspended from the ceiling, these fans generate a powerful vertical airflow that efficiently cools and circulates air in large spaces. Whether you're looking to refresh a compact area or cool down a spacious room, the choice between wall HVLS fans and ceiling HVLS fans will depend on your specific needs and the desired airflow pattern.
