Large HVLS Fans
HVLS (High Volume Low Speed) fans blanket a very large area with constantly moving air to create an expansive comfort zone. As a result, this large ceiling fan can create an evaporative cooling effect of 37-39°F (3 to 4°C) throughout the facility. Our product line includes three different models a heavy-duty durable model for maximum air movement, a sleekly designed commercial model for high visibility applications, and the affordable HVLS fan that gets the job done. Providing years of reliable airflow on any budget, this line of well-designed, quiet overhead fan keeps your environment ventilated and your energy bills low
When used in the summer to encourage evaporative cooling, HVLS fans are run forward, blowing air at the floor. When used for destratification in the winter, the fans are run in reverse, blowing air towards the ceiling, which then circulates around the room. The height at which HVLS fans can be effective is limited in comparison to axial destratification fans.

Frequently Asked Questions
Quick Links
What is an HVLS fan and how does it work?
HVLS (High Volume Low Speed) fans are large-diameter ceiling fans designed to move substantial volumes of air at relatively low rotational speeds. Unlike conventional high-speed fans that create concentrated airflow, HVLS fans generate a broad column of air that circulates throughout a large area. During warmer months, the fans operate in forward mode to create an evaporative cooling effect that helps occupants feel more comfortable. During colder months, they can operate in reverse to circulate warm air trapped near the ceiling back into the occupied space.
Where are HVLS fans commonly installed?
HVLS fans are widely used in warehouses, manufacturing plants, distribution centers, gymnasiums, agricultural facilities, retail spaces, commercial buildings, aviation hangars, and other large open environments. They are particularly effective in facilities with high ceilings where air stratification and uneven temperatures can become significant issues. Commercial models are also available for customer-facing environments where aesthetics are important. The ideal fan size and configuration depend on building dimensions, ceiling height, and airflow requirements.
What are the differences between the SAILFIN, Alite 3, and Jazz fan models?
The Direct Drive Altra-Air SAILFIN is a heavy-duty, industrial-grade HVLS fan designed for maximum airflow and durability, featuring a gearless design and minimal maintenance requirements. The Alite 3 is a cost-effective three-blade solution that delivers significant airflow while minimizing weight and operating costs. The Jazz fan is designed for highly visible commercial applications and combines modern aesthetics with efficient airflow, integrated controls, and optional LED lighting. Each model is engineered to serve different facility requirements, budgets, and design objectives.
Can HVLS fans help reduce energy costs?
Yes. HVLS fans can help improve the efficiency of existing HVAC systems by promoting more consistent air circulation throughout a facility. In the summer, increased air movement may allow facilities to maintain occupant comfort at higher thermostat settings. In the winter, reverse operation helps destratify warm air that naturally collects near the ceiling, reducing temperature imbalances. By improving airflow and thermal consistency, HVLS fans can contribute to lower heating and cooling demands in many applications.
What control options are available for HVLS fan systems?
Multiple control platforms are available depending on the application and number of fans being managed. Options include single-fan variable frequency drive controls, centralized control systems capable of managing dozens or even hundreds of fans, and solutions that integrate with building automation systems using BACnet communication. Advanced control systems support features such as fan grouping, variable-speed adjustment, remote diagnostics, daisy-chain communication, and simplified facility-wide fan management. These capabilities allow operators to optimize airflow performance across the entire building.
