When purchasing an HVLS (high-volume, low-speed) fan for the first time, you may be unsure which model will work best for you and your building. If you're like the average buyer, you'll have a few basic questions, such as...

What is the distinction between a direct drive motor and a standard motor? What exactly is an IP rating? How much power do you require? Is it true that size matters? Should you get a 1 or 2-horsepower motor? What exactly is a Fan Chief controller?

Fan Specifications For HVLS

Every HVLS fan model is built with features that set it apart. Here's a rundown of the key features you can expect to find on every HVLS fan model.

Important Features

The room temperature is not lowered by HVLS industrial fans. Instead, they create pressure, which circulates air throughout the structure. The breeze from the fan makes a person feel cooler by blowing across their sweaty skin. So, while the thermometer reads 86° F (30° C), it feels closer to72° F (22° C).

Diameter

Diameter refers to the width of the fan from one end of an air foil to the other. While the fan is spinning, it is the total size of the fan. The size you select is determined by the dimensions of the room where the fan will be installed as well as the volume of air that must be circulated.

Motor

Every HVLS fan includes a motor that powers the fan. Motors typically range in horsepower from 0.5 to 2.0. (HP). Direct-drive motors, such as the Neodymium magnet motor that powers the AmeriWind Fans, are designed to run virtually silently and to last for decades with no maintenance.

Mounting

The location of your fan has a significant impact on its effectiveness in your building. It must be centered in the best possible location for maximum airflow, as well as the proper height from the ground and distance from the ceiling. AmeriWind Fans specification sheets indicate which mounting options are available for each fan model, such as I-beams or bar joists.

Warranty

The specification sheet will also tell you what kind of warranty comes with the fan. Higher-end models typically have longer warranties that cover the electrical and/or mechanical functions of the HVLS fan.

Technical Description

While it's not surprising that engineers are drawn to an HVLS fan's technical specifications, these details can be quite useful in informing you how the model will perform in your environment.

This section is especially useful for determining the best fit for your building. The dimensions, weight, speed, electrical requirements, motor horsepower, height clearance, and maximum operating temperature of a fan are all precisely measured.

Features Of The Construction

This section also includes various industry ratings for each required part. For example, IP ratings (ingress protection) indicate how well the casing will protect against elements such as dirt and water. The Power foil®X gearbox has an IP56 rating, which means it offers level 5 protection from solid matter (such as dust or tools) and level 6 protection from liquids. The greater the number, the greater the level of protection.

HVLS fans require controls because they are installed high and out of reach. The specification sheet specifies the type of controls included with each model (whether standard or optional) and the industry protection rating.

You'll also discover whether the controls are compatible with other automated building systems, such as fire suppression.
