HLVS fans are huge ceiling fans. They are greater than 7 feet in diameter. Unlike the personal fans you use at home, HVLS fans rely on their size, not speed, to move a large amount of air. HVLS fans produce columns of air, which flow down and horizontally along the floor until the column hits a side wall or another fan that carries it further.

Some HVLS fans have gearbox motors, others are equipped with direct-drive motors. Direct-driven HVLS fans are more cost efficient than gearbox-driven fans.

HVLS fans help you maintain moderate temperature, and help circulating the fresh air. The fan will mix the fresh air with the stale air and gradually ventilate your working environment.

HVLS fans work on the principle that cool air brakes up the moisture-saturated boundary layer surrounding the body and accelerates evaporation to produce a cooling effect. Ceiling fans produce a column of air as they turn.

Unlike traditional ceiling fans, HVLS fans rely on large fan blades and low speed to quietly and effectively move air throughout a facility. This helps eliminate stagnant air, which can be extremely unhealthy for your employees, from within your facility. The Centers for Disease Control and Prevention (CDC) says one of the number one things you can do to prevent viruses in your building is to improve ventilation. A  HVLS fan can increase airflow supply within a building, which plays a huge part in increasing air circulation. 

Uncomfortable temperatures in your building can cause alarming rates of unproductive employees. The National Aeronautics and Space Administration (NASA) found slight increases in temperatures can make a huge impact in worker productivity and accuracy rates. For example, in their study they found a 400% uptick in employee inaccuracies when the temperature rose from 90 to 95 degrees. When employees are comfortable, they’re happier and more productive.

In the summer, the fans drop the effective temperature in a building allowing you to use less energy. High volume low speed fans make the “feel like” or perceived temperature six to eight degrees lower than the actual temperature in the building, thus allowing you to use less energy to cool the area down. The fans circulate the air, producing an evaporative cooling effect on the human skin. This means your thermostat can be set to a higher temperature and won’t need to use as much energy.

High-volume low-speed, or HVLS fans, are starting to become an energy-saving staple in industrial, commercial, and residential spaces. They are growing to become a major player in warehouses and factories due to their ability to lower energy costs, increase quality control, and improve air circulation, among other benefits.

HVLS fans are an effective solution to your ventilation and air quality pitfalls. They will lower your high heating and cooling bills, decrease your energy usage, create a comfortable environment for your employees increasing their productivity levels, and fulfil the need for better ventilation. 

In early 2022, we received an order from Willing Hearts for 2 units of HVLS fans for their central kitchen in their Telok Kurau facility.

Willing Hearts is a secular, non-affiliated charity, Willing Hearts is wholly run by volunteers, apart from a handful of staff. It operates a soup kitchen that prepares, cooks and distributes about 11,000 daily meals to over 70 locations island wide, 365 days a year…


Installation at Willing Hearts was a challenge.
Since they are already operating in their current facility, measurement and cabling has to be done after their operation hours, i.e., after 6pm.

Both installations were completed within 2 evenings.
