HVLS fans are quieter, are energy-saving high-speed small ceiling or drum fans.

Traditional fans commonly operate in high speed that may cause many challenges. These challenges include energy costs, temperature control, air quality and safety/comfort issues. In an effort to mitigate these challenges, more and more business owners are installing high-volume, low-speed (HVLS) fans. HVLS fans can significantly improve the comfort and health of workers, guests and mechanics. On top of that, they can save building operators substantial amounts of money by making existing heating and ventilation systems more efficient, while providing additional benefits in buildings with no air conditioning.

HVLS VS other types of fans

High-speed ceiling or floor fans can help increase air movement, but they have several disadvantages when compared to HVLS ceiling fans. HVLS fans can move larger volumes of air; a single fan can cover an area up to 132000 square feet; and can replace as many as 10 to 20 floor (or smaller) ceiling fans.

HVLS fans are quieter, less disruptive and consume less energy than traditional, high-speed ceiling or floor fans. Reducing the amount of floor fans can reduce clutter on the ground and minimize the chance of an accident.

HVLS complements HVAC

The key to HVLS fans is that their big size long blades (up to 24ft total fan diameter) spin much more slowly than a traditional ceiling or floor fan. Their unique blades are specially designed to capture the maximum amount of air possible and push it softly to the floor.

In the summer, the gentle breeze created by an HVLS fan keep employees and visitors cool by quickening the evaporation of sweat. In winter, in a process called destratification, the fans take the warm air created by an HVAC heater and pull it down from the ceiling to the floor level, allowing people inside to be more comfortable with a lower thermostat setting. Energy savings add up

A 24ft diameter model uses 1.5KW per hour for cooling and as little as 0.1 watts for destratification, making HVLS fans extremely energy efficient. This translates to operating costs of as little as a few cents per hour. During the winter months, HVLS fans can reduce energy consumption by up to 30 %. When used to supplement air conditioning, the fans help lower the perceived temperature- which means thermostat set-points can be raised. Because energy costs are reduced roughly 4 percent for every degree the set-point is raised, a 3 to 4 degree increase in the set-point can reduce energy consumption by 12 to 16 %. With year-round use, HVLS fans can pay for themselves in as little as six months.


Advantages of HVLS fans

1. Human Comfort

HVLS fans distribute that incoming air, driving it quietly but forcefully to the floor where it jets to the walls before it rises to blend with the incoming air. HVLS fans not only move the air, but they also effectively de-stratify the air.

2. Energy Savings

A single 24-foot diameter fan can run for eight hours at 31¢ per day. The aerodynamic blades even cool the fan motors to reduce temperature and stress.

3. Risk Management

The fans have the power to restructure the air so that it evaporates moisture and disperses it within the volume of the space.HVLS fans don’t waste energy trying to dry things or reduce humidity; they make humidity within that space remain equally dispersed opposed to migrating down onto the things that might be at dew point.
