![]() ![]() Anything below will result in less airflow, and anything higher will be more powerful. The number measures the fan alone, not including a fan’s light fixture (if it has one). Similar to light bulbs, a fan’s electricity is measured in watts. Your average fan moves about 4,000 CFM, while the most powerful fans move around 10,000 CFM. It’s the key metric when comparing ceiling fans. Measured in Cubic Feet per Minute (CFM), airflow is the volume of air a fan moves at high speed. All data is gathered by testing fans at high speed - a requirement by the EPA. Much like many lighting labels, the ceiling fan Energy Information Label provides details on energy efficiency and airflow. Every ceiling fan on Lightology includes this label in the product images. If you’re unsure, Wet Rating is probably the safest bet.Īs of January 2009, the EPA requires ceiling fan manufacturers include an Energy Information Label with each product (excluding some specialty and decorative fans). If the fan is more exposed to rain or snow, you’ll want to go with a Wet Rated-fan. For outdoor environments, if fully covered and only slightly open to the elements, a Damp Rated-fan may be all you need. This ensures the fan is suitable to withstand frequent condensation. However, if you have a bathroom that’s particularly steamy, or you’re outfitting a spa with ceiling fans, look for the Damp Rating. Most bathrooms can use a standard ceiling fan, you’ll just want to make sure the size is right. You want a minimum of 1 foot between the blade and the ceiling, and if your fan blades are too close to the ceiling, you may need to buy a downrod extension for that extra clearance.Īre there fans for damp or wet environments, like a bathroom fan or outdoor fan? The other thing to consider is how close your blades come to the sloped ceiling. For more extreme slopes (higher than 30 degrees), you may need a slope-ceiling adapter. Anything under 30 degrees will typically work with your standard downrod fan. Non flush-mount ceiling fans come with a downrod, which many times has a ball at the top of the downrod that pivots to accommodate a slope. You can immediately rule out any hugger or flush-mount ceiling fans - those are not meant for sloped ceilings. In fact, most ceiling fans will work on a sloped ceiling. Will a ceiling fan work on a sloped or vaulted ceiling?Ĭeiling fans for sloped or vaulted ceilings are - surprisingly - a dime a dozen. ![]() Always look at the CFMs on the label to get the airflow you’re looking for, then select how many blades you want, aesthetically speaking. The main determining factor in airflow is the pitch of the fan blade: The more exaggerated the angle, the higher the airflow. Not at all - blade number is purely aesthetic. Your average fan is around 4,000 - 5,000 CFM at high speed. The higher the CFM, the more powerful the fan. ![]() Are you looking for something powerful, or a calm, gentle breeze? Each ceiling fan comes with an Energy Information label (see below) which measures airflow in CFM. ![]() Many fans will work with vaulted and sloped ceilings, they may just require an extended downrod for clearance. You’ll also want to take into consideration the ceiling slope. Most building codes require ceiling fans be at least 7 feet above the floor. For larger, commercial applications, you’ll want an extra large (60” and over) commercial-size fan. For more open spaces, a large (50” - 60”) should do the trick, or a few fans if you’re working in a longer, more narrow layout that has more than one junction box. My rule of thumb: If a room is 11 x 11, go with a small (under 30”) or medium (30” - 50”) size. Ceiling fans are not a one-size-fits-all item. You’ll want to measure length, width and ceiling height.
