How They Work
Big Ass Fans are the highest quality, highest engineered HVLS fans on the planet. HVLS stands for High Volume / Low Speed. This means Big Ass Fans move a lot of air with their size (which is up to 24-ft. in diameter), not speed. Moving at a low speed means less energy used for operation, which translates into more energy saving for you. Big Ass Fans aren't just for when it's hot. Big Ass Fans can save you money and keep you comfortable year-round.
Summer Cooling
Nature put us on earth with a built in air conditioner: Smart. We engineer our Big Ass Fans to make the most of it: Smarter. Thanks to a steady, gentle breeze, Big Ass Fans "cool" by increasing the rate at which perspiration is evaporated from the skin's surface. In some cases, our fans make the surrounding area feel between 8 - 16ºF cooler! See what we're talking about.
Energy efficient and cost effectiveness: Smart.
You: Smartest.
Winter Heat Recirculation
It's not uncommon for the temperature to differ 20ºF from floor to ceiling especially in the winter. Say you have a building with a ceiling height of 30-ft. and it feels as though you’re in Nome, Alaska, yet you’re really just in your office. Install a Big Ass Fan and gently drive that hot air trapped at the ceiling down to the floor, while reducing your heating bills 25% or more. That's more than enough to make you feel all warm and cozy inside. Take a look.
