What is a High CFM Outdoor Ceiling Fan
Outdoor spaces like patios, decks, and pergolas are great for entertaining guests or simply relaxing on a nice day. However, things can get uncomfortable fast when the weather is hot and humid. This is where a high CFM outdoor ceiling fan comes in handy.
A high CFM (cubic feet per minute) rating means the fan moves a substantial volume of air. This increased airflow circulates fresh air and cools people below much more effectively than standard fans. But what exactly qualifies as "high CFM," and what should you look for when choosing an outdoor ceiling fan to keep your patio or pergola comfortable?
What is CFM?
CFM is an abbreviation for "cubic feet per minute." It refers to the amount of air a fan can move in one minute. For example, a fan with a CFM rating of 6,000 can move 6,000 cubic feet of air per minute.
Higher CFM equates to more airflow and increased cooling capacity. Outdoor ceiling fans with CFMs ranging from 6,000 to 8,000 or more are generally considered "high velocity." They have the power to keep large outdoor living spaces cool and comfortable.
Benefits of High CFM Outdoor Ceiling Fans
There are several key reasons you may want to choose a high CFM outdoor fan over a standard model:
- Increased airflow: The whole point of a high CFM fan is moving large volumes of air for superior cooling power.
- Suitable for large spaces: High CFM fans are necessary to properly circulate air in big patios, pergolas and sitting areas.
- Energy efficiency: The motors in high CFM outdoor fans are designed for optimal airflow without high energy bills.
- Adjustable speeds: Most high-powered outdoor fans feature settings from low to max CFM output.
For porches, patios, decks, and pergolas larger than 300 square feet, a standard fan just won't provide enough power. The minimal airflow will leave people feeling hot and frustrated rather than relaxed.
How Ceiling Fan CFM is Measured
An anemometer is used to precisely measure the airflow generated by a ceiling fan in cubic feet per minute. Tests are performed in a specialized laboratory environment under strict guidelines. This ensures accurate CFM readings that allow consumers to compare different brands and models.
Factors like blade angle/pitch, size, motor, and speed all impact ceiling fan CFM. Manufacturers design the parts to work together for optimal airflow without excessive energy use. Of course, higher maximum speeds equate to more cooling power but may require a higher voltage power source.
What to Look for in a High Airflow Outdoor Fan
Once you decide that a standard fan won't properly cool your outdoor living space, the challenge becomes choosing the right high CFM ceiling model. Keep these key factors in mind when evaluating your options:
Powerful, Energy-Efficient Motor
The motor powers the spinning blades that create airflow. Brushless motors provide peak efficiency compared to outdated brushed motors. Make sure your outdoor ceiling fan has an energy-efficient motor with enough horsepower for the CFM rating.
Blade Design
The blade quantity, size, angle/pitch and shape impact performance. More blades don't necessarily equal more airflow. The design of each individual blade matters most. Curved blades with an efficient angle between 12 and 14 degrees work well for high CFM fans.
Durable Materials
Outdoor ceiling fans endure all sorts of weather conditions from sun exposure to rain, snow, and salt air near oceans. Quality manufacturing includes weather-resistant materials like tempered glass globes, sealed motors, and durable polymeric blades.
Variable Speeds
High CFM fans should include adjustable speed settings from low for gentle breezes to max for really hot days. Wall units, remotes, or pull chains allow easy control of airflow. Plus, variable speed equals energy savings during mild weather.
Reputable brands like Hunter and Minka Aire specialize in outdoor ceiling fans to suit different size spaces and design aesthetics. Consult an experienced retailer like Hansen Wholesale to pick the right model.
Where to Install Your High Airflow Outdoor Fan
Positioning your high velocity outdoor ceiling fan is almost as important as choosing the right model. Consider the size, typical uses, and layout of your outdoor space. Also factor in optimal positioning for airflow that reaches people without obstructions.
Patio and Porch Areas
Most homeowners install ceiling fans in covered patio and porch areas used for entertaining, dining, or relaxing. For spaces up to 300 square feet, a fan with 6,000+ CFM works great. Go bigger for larger gatherings and big patios.
Pergolas and Gazebos
Another prime spot is a pergola or gazebo with an overhead structure suited for fan installation. Just make sure there's enough clearance for spinning blades. These "outdoor rooms" also call for high powered fans around 6,000 CFM or more.
Covered Sitting Areas
Shaded sitting spaces adjacent to decks, pools, gardens and other activity areas stay cooler with a high velocity fan circulating fresh air. Go for ceilings fans with CFMs between 4,000-6,000 for sitting areas under 300 square feet.
Work with an experienced installer to choose mounting locations optimal for circulating air properly around the space without obstructing foot traffic patterns or vehicle access points.
How to Choose the Best High Airflow Outdoor Fan
The range of outdoor ceiling fans on the market today provides options for all types of outdoor spaces. As you evaluate models, keep an eye on CFM ratings, size for your area, and brand reputation.
CFM Ratings
Compare cubic feet per minute measurements tested under laboratory conditions rather than vague marketing claims. This gives you an accurate picture for comparing true cooling capacities.
Blade Span
The blade span or diameter (measured tip-to-tip across the blade set) matters for optimal coverage. Spans from 44-60 inches work for small to mid-size spaces. For larger patios and pergolas, look for blade spans from 60-72 inches.
Quality Brands = Better Performance
Well-known manufacturers like Hunter, Hampton Bay and Minka Aire invest in product design, testing and warranties. Review industry awards, customer reviews and specialized publications to compare brands.
Professional Installation
An expert electrician ensures proper wiring, fittings and mountings tailored to your outdoor space and local building codes. This avoids safety issues while maximizing your fan's functionality and lifespan.
Once your new high CFM outdoor ceiling fan is professionally installed, take steps to operate it safely while keeping it in optimal condition:
- Run on the lowest speeds needed for sufficiently cooling your space to conserve electricity.
- Use the reverse mode to change airflow direction as the seasons change.
- Turn off fan when not needed and safeguard electrical components from rain and snow.
- Follow the manufacturer's instructions for cleaning fan blades and motors.
- Lubricate moving parts and tighten fittings over time.
- Replace frayed cords and faulty electrical components immediately.
With sizes exceeding 72-inch blade spans and CFMs over 7500, today's high velocity outdoor ceiling fans deliver enough cooling power for practically any porch, patio or outdoor living space a homeowner could want. Just choose a durable, energy-efficient model suited to your specific area and activities.
And don't forget - a professional installation tailored to your unique outdoor structures ensures your fan provides comfort, beauty and functionality for years of backyard entertaining to come.
