Choosing the Best HVLS Fans

Investing in an HVLS (high-volume, low-speed) commercial, industrial or warehouse fan can bring numerous benefits to your company. Improved employee comfort, increased productivity, energy savings, and a healthier working environment are just a few advantages these fans offer. However, with the plethora of HVLS fans available on the market, selecting the most effective one can be a challenging task.

We will explore the key factors to consider when choosing the best HVLS fans for your warehouse.


When evaluating HVLS fans, their performance in circulating air throughout your building is a crucial consideration. While most HVLS fans can move large volumes of air, the specifics of their performance can vary significantly. To accurately assess a fan's performance for your specific building, it is advisable to request demonstrations from manufacturers. Companies like JSO MacroAir provide precise computer simulations to give you a clear idea of how their fans will perform in your warehouse.


The energy consumption of an HVLS fan is another important factor to consider. The motors, blades and other components can differ between fans, affecting their ability to operate with reduced electricity usage. Estimating a fan's energy consumption can be challenging due to various variables, but reliable HVLS fan manufacturers can provide detailed information and calculations to help you determine the fan's efficiency accurately.


For many buyers, minimizing noise disturbance is a significant concern when choosing an HVLS fan. Sound output can vary widely among different fan models, and some manufacturers provide decibel measurements for each fan. Direct drive motors generally tend to be quieter compared to standard motors with gearboxes. Taking noise levels into account ensures that your employees can benefit from the fan's advantages without any disruptions.


Consider the available options and additional features offered by HVLS fan manufacturers. These may include remote controls, integration with security systems, air purification equipment, building management system (BMS) integration, and even customization options such as different color choices. Assessing the available options allows you to select a fan that aligns with your specific requirements and preferences.

Technology Features:

The extent of computer technology utilized in HVLS fans can vary significantly between brands and models. The best HVLS fans incorporate advanced technology for efficient control, timing, security, monitoring, and integration with other systems such as HVAC and fire suppression. Assessing the technological features of an HVLS fan can help you determine its compatibility with your existing infrastructure and automation requirements.

Understanding Your Space:

Before contacting an HVLS fan manufacturer, gather specific details about your warehouse to ensure an accurate recommendation.

  1. Dimensions: Provide accurate measurements of your space, including ceiling height, width, and length. Consider the interior layout of the building, accounting for factors like industrial shelving, machinery, or any obstacles that might impact air circulation.

  2. Existing Systems: Communicate information about existing systems in your building that may need to integrate with or accommodate the HVLS fans. Common examples include HVAC, security, and fire suppression systems.

  3. Working Conditions: Be prepared to answer questions regarding the number of people in the building, their working and movement patterns, the overall atmosphere inside the warehouse, and any other relevant factors that may impact fan placement and performance.

Consulting with an Expert:

Engaging in a conversation with an airflow expert from a reputable HVLS fan manufacturer, such as JSO Macroair, can provide valuable guidance. These experts possess extensive knowledge, employ advanced tools like AirViz simulation software, and adopt a customer-focused approach. By leveraging their expertise, you can make an informed decision and select the ideal HVLS fan solution to enhance comfort and productivity within your warehouse.
