HVLS stands for High-Volume, Low-Speed. These are large-diameter ceiling fans designed to move massive amounts of air at low speeds, creating a comfortable breeze across large areas.

They destratify air—mixing hot and cool layers—to keep temperatures even, which means your HVAC doesn’t work as hard. This can reduce energy use by 20–30%.

Anywhere with open space and high ceilings: warehouses, barns, gyms, production floors, sports facilities, even large retail spaces.

Cool Boss HVLS fans are built to deliver the same high-volume airflow as competitors like Big Ass Fans but at a value that keeps ROI high. Our focus is durable construction, energy efficiency, and ease of installation.

A single HVLS fan can move up to hundreds of thousands of cubic feet of air per minute, covering areas that would need multiple small fans.

Yes. HVLS fans push warm air down in winter and circulate cool air in summer, helping stabilize temperature year-round.

No. Despite their size, they run quietly thanks to precision motors and balanced blades.

Most install on standard power and can integrate with building systems. Larger units may need three-phase power.

Minimal. Occasional inspection and cleaning of blades and motor housing is usually all that’s required.

It depends on your square footage and ceiling height. Cool Boss experts can recommend the right diameter and quantity to maximize efficiency.
