In today's climate, the "new normal" emphasizes prioritizing the safety of customers and employees. One critical aspect to consider is air ventilation; keeping air circulating prevents unhealthy air from stagnating within a building. Commercial HVLS fans can improve ventilation significantly by creating a consistent airflow throughout your facility. Enhanced air quality is just one of the many advantages offered by high-volume, low-speed HVLS fans.
What are HVLS fans?
HVLS fans are industrial ceiling fans with diameters greater than 7 feet. Unlike personal fans commonly used at home, HVLS fans rely on their size rather than speed to move large volumes of air. They create columns of air that descend and flow horizontally until they reach a side wall or another fan that further distributes the air.
Some HVLS fans are equipped with gearbox motors, while others utilize direct-drive motors. Direct-driven HVLS fans are generally more cost-effective than gearbox-driven fans.
What are the benefits of HVLS fans?
The benefits of HVLS fans extend beyond financial savings to include improvements in employee welfare. Below are some key reasons to consider installing HVLS fans in your buildings, whether a distribution center, factory, warehouse, or similar industrial setting.
HVLS fans enhance air circulation and promote employee health.
Indoor air quality is crucial for employee health. Unlike traditional ceiling fans, HVLS fans use large blades and low speeds to effectively move air quietly throughout a space.
This prevents stagnant air, which can be detrimental to employee health. The Centers for Disease Control and Prevention (CDC) emphasizes that improving ventilation is one of the most effective strategies to prevent viruses in buildings. An industrial HVLS fan can significantly increase airflow within a facility, greatly enhancing air circulation.
Commercial high-volume low-speed fans boost productivity and ensure safer working conditions.
Uncomfortable temperatures can lead to decreased employee productivity. Research by the National Aeronautics and Space Administration (NASA) shows that even slight temperature increases can profoundly impact worker accuracy and productivity. For instance, their study found a 400% increase in employee inaccuracies as temperatures rose from 90 to 95 degrees. Comfortable employees tend to be happier and more productive.
Commercial HVLS fans are installed in the facility's ceiling, eliminating the need for bulky fans and reducing trip hazards like extension cords. This allows employees to move freely in a safer environment.
HVLS fans help achieve energy efficiency goals in all seasons.
In summer, fans help lower the effective temperature in a building, resulting in less energy consumption. HVLS fans can make the perceived temperature feel 6 to 8 degrees lower than the actual temperature, allowing you to set the thermostat higher without compromising comfort, thus saving energy.
High-volume low-speed fans balance temperatures in winter, significantly reducing heating costs.
HVLS fans can run in reverse to promote destratification, mixing warm air trapped at the ceiling with cooler air at floor level, creating an even temperature throughout the space.
A commercial HVLS fan can potentially save up to 30% on HVAC heating costs by minimizing thermostat activation and reducing heat loss through the roof.
Rick Krug, a business owner, experienced these cost-saving benefits firsthand in his Northern Arizona restoration service company, where he stored trucks in a large warehouse. After installing HVLS fans, he noticed a dramatic reduction in his electricity bill, realizing his heating costs dropped by at least 25%, sometimes even 50%, just by effectively moving air.
HVLS fans operate daily for minimal costs.
HVLS fans are both affordable and cost-effective. They function optimally at low speeds, requiring minimal energy to operate. Many models come with a touchscreen controller that allows you to adjust fan speed based on specific needs, leading to greater savings.
Pro Tip: Maximize savings by choosing an HVLS fan with a direct-drive motor instead of a gearbox-driven model. Direct-drive motors require less maintenance, eliminating concerns about servicing, oil changes, or seal replacements.
HVLS fans offer numerous applications across various industries.
HVLS fans enhance value and comfort across a broad range of operations. They help keep insects and odors away in agricultural applications, improve employee health and morale in warehouses and factories, reduce condensation, and mitigate rust on equipment. In food and beverage manufacturing, HVLS fans prevent spoilage and maintain crucial temperature control. They can also deter birds from nesting in facilities where doors are frequently open.
