When choosing a ceiling fan for your greenhouse, choose a high quality one that is sturdy. Cheap ones are often made of inferior materials and have weak airflow. Invest in a heavier one made of stronger and more durable materials, such as galvanized steel. These fans have thick blades and are quite efficient.
J&D Manufacturing produces exhaust and circulation fans, aluminum shutters, evaporative pad cooling systems, and other ventilation equipment for nurseries and greenhouses. They are renowned for providing quality products at competitive prices. Designed for optimal performance and durability, they are available with an automatic thermal protection system to prevent overheating and corrosion.
When choosing a fan for a greenhouse, the CFM, or cubic feet per minute, rating is very important. CFM measures how much air is moved by a fan in a minute, so you need to choose one that moves a similar volume of air to the total cubic feet of your greenhouse. One CFM is equivalent to approximately two litres of air per second.
Galvanized Box Fans
If you’re looking for a fan to cool your greenhouse, consider a Galvanized box ceiling fan. These ceiling fans offer superior cooling while requiring minimal maintenance. They’re also UL507 certified for safety and durability. And because they’re pre-wired, they’re ready to install instantly.
Galvanized box fans are made from durable materials and offer high air output. They are ideal for greenhouse applications, livestock barns, and industrial facilities. They’re compact and easy to install, and the direct-drive design means they use less energy than other, belt-driven fans.
Vertical Air Flow (HAF) fans
A horizontal airflow system provides even temperatures, better fog coverage, and better penetration of foliage. Using a HAF system also saves on heating costs. Depending on the electricity rate, an HAF fan can operate for as little as $0.24 per day. This type of air circulator is a great choice for greenhouses that require high levels of air circulation.
The placement of HAF fans depends on the greenhouse’s layout. A fan in front of a wall can be installed at one end, blowing the air toward the louvers and vents on the opposite wall. A mid-range fan is best placed below the basket level and about 40 to 50 feet away from the end wall.
Solar-powered exhaust fans
A solar-powered exhaust fan is an excellent solution for greenhouses without electricity. These devices are designed to work with a solar panel and include a shutter and thermostat to control fan speed. They are also available with manual louvers to complete the package. These units are available in three different sizes.
An AntPay fan is the most durable solar fan available. It is especially great for arctic tundra greenhouses. Its double-layered metal protection net helps protect against animals getting trapped inside the fan. However, it is not a continuous fan and requires plenty of sunlight to run.
HVLS ceiling fans for greenhouses are designed to move air efficiently and effectively. Their large diameter enables them to cover a much larger area than smaller ceiling fans. This improves air circulation, reducing humidity. Too much humidity promotes the growth of pathogens and pests. A HVLS fan is ideal for these applications, because it can move big amounts of air without creating a huge noise level.
The HVLS ceiling fan can move air up to 85 feet (26.0 m) from its center. This large area of movement helps to reduce energy bills and improve comfort in large agricultural facilities. Compared to a high-speed fan, HVLS ceiling fans run at very low speeds, which reduces strain on the motor. They also reduce condensation on floors and improve the indoor air quality in agricultural buildings.
DC Infinity fans
The DC Infinity ceiling fan is a smart design from Fanco. It is suitable for coastal and covered outdoor areas and provides gentle rotation for quieter areas. The motor of this fan moves up to 9,409 cubic metres of air per hour at its highest speed. It features ABS and electroplated metal components, and can be installed indoors and outdoors.
DC Infinity ceiling fans are available in six speeds. They can be manually operated with a remote control. They should be installed 1.5 meters from the perimeter of the roof, eaves, and apex. The Fanco Infinity-ID DC ceiling fan comes with a three-year motor warranty and is suitable for coastal or covered outdoor applications.
