Buyer's Guide

How To Choose The Best Squirrel Cage Fan

What Is The Purpose Of A Squirrel Cage Fan?

The purpose of a squirrel cage fan is to provide air circulation within a room by moving warm air upward and cool air downward. In most cases, these fans are placed near windows or vents so that hot air rises and cold air falls. If there is no window or vent available, squirrel cage fans can be installed inside walls or ceilings to create natural ventilation.

How Does A Squirrel Cage Fan Work?

Squirrel cage fans consist of two parts: a motor and a set of metal bars called "squirrel cages." The squirrel cage design creates a series of small chambers where heat rises and cool air descends. As the wind blows across the squirrel cage, the blades rotate causing the squirrel cage to spin around its axis. Because the squirrel cage spins rapidly, it produces a strong updraft which pulls cooler air into the chamber. Conversely, because the squirrel cage rotates slowly, it causes a downdraft which pushes warmer air out of the chamber.

Advantages of Using A Squirrel Cage Fan

There are several advantages to using a squirrel cage fan. First, squirrel cage fans produce more airflow per unit of power compared with other types of fans. Second, squirrel cage fans are quiet. Third, squirrel cage fans are easy to install. Fourth, squirrel cage fans are inexpensive. Fifth, squirrel cage fans last longer than conventional fans. Sixth, squirrel cage fans require little maintenance.

Disadvantages of Using A Squirrel Cage Fan

Although squirrel cage fans are very effective, they are not suitable for rooms with high humidity levels. Also, squirrel cage fans cannot be operated continuously; therefore, they must be turned on periodically to maintain adequate airflow.

Where To Install A Squirrel Cage Fan

Most squirrel cage fans are designed to operate best when mounted above a ceiling or wall. However, if you prefer to mount a squirrel cage fan directly below a window, you can purchase a special mounting bracket specifically designed for this application. Another option is to hang a squirrel cage fan from the top of a door frame. Finally, you could simply remove the glass pane from the bottom of a window and attach the squirrel cage fan directly to the outside of the window frame.

Types of Fans

Each type has different characteristics and uses. For example, centrifugal fans blow air outward while axial flow fans push air inward. Mixed-flow fans combine both features. Centrifugal fans are typically used in large spaces since they generate greater volumes of air. Axial flow fans are generally smaller and quieter. Mixed-flow fans are commonly found in medium sized spaces.

Benefits of Using An Axial Flow Fan

Axial flow fans are ideal for cooling rooms with low humidity levels. Since axial flow fans pull air in rather than pushing it out, they consume less electricity than centrifugal fans. Furthermore, axial flow fans are easier to control than centrifugal fans. Lastly, axial flow fans are relatively inexpensive.

Cage fans are essential tools for anyone who wants to create a comfortable environment inside their homes. If you're planning on starting a small business, investing in a good cage fan could be the best thing you ever did. In fact, there are many reasons why you should invest in a high-quality cage fan.

Insects can cause serious health problems for humans. For example, cockroaches carry bacteria that causes diarrhea and other diseases. Cockroach droppings can also lead to allergies and asthma attacks. To avoid these issues, you must ensure that insects aren't living in your house. One way to achieve this goal is by using a cage fan. With a cage fan, you can effectively remove pests from your property while creating a more pleasant indoor atmosphere.

As mentioned earlier, air flow plays a vital role in maintaining comfort levels within our houses. Without adequate airflow, we might experience stuffy rooms, which can result in headaches and fatigue. Fortunately, a cage fan can increase air circulation throughout your entire home. That's enough air movement to cool down a room with a single occupant.

Features To Look For When Buying A Squirrel Cage Fan

The most important thing to know before purchasing a squirrel cage fan is whether or not it has a motor with variable speed control. If you're going to be using your fan frequently, it makes sense to invest in a fan with variable speed control so that you can adjust its output depending on the amount of air flow needed. The best fans with variable speed controls include those manufactured by BSH, Delta, and Dyson. Fans with fixed speeds are good enough for occasional use, but if you plan on using your fan regularly, you might want to go with a fan with variable speed control.

Variable Speed Control

Fans with variable speed controls allow you to change the airflow rate while maintaining constant noise levels. Variable speed fans are ideal for situations where you want to conserve electricity because they reduce power consumption during periods of low demand. In addition, these fans run quieter than standard models because they operate at lower RPMs. Most variable speed fans start between 1, 500-2, 000RPM and reach maximum speeds around 3, 000-4, 000RPM. Some fans can reach higher speeds, but only if you pay more money for them.

Airflow Rate

Another factor to consider when choosing a fan is the size of the fan blades. Smaller fans produce greater air volume per unit of electrical input, which translates into increased cooling capacity. However, larger fans generate more static pressure, which increases comfort level. Generally speaking, fans with smaller blades are preferred for small rooms and offices, whereas fans with large blades are suitable for medium sized spaces.

Noise Level

Fan noise isn't always bad; sometimes it's necessary. But excessive noise can cause problems. So, if you're planning on installing a fan in a room where others live or sleep, choose a model with a quiet operation.

Cord Length

Some fans require long cords to connect them to AC outlets. Others can be plugged directly into wall sockets. Cord length is measured in inches, so check the specifications carefully before making your purchase.


Most fans last anywhere from 5-10 years. But if you're concerned about durability, opt for a fan with a longer warranty period. Manufacturers typically provide warranties ranging from 2-5 years.

Energy Efficiency

It doesn't matter how powerful a fan is if it uses too much electricity. Energy efficiency ratings range from 0.7W/CFM to 4.0 W/CFM. Higher numbers indicate a fan that consumes fewer watts of electricity.

Installation Type

There are two types of installation methods available for fans: ceiling mount and floor stand. Ceiling mounts generally consist of a bracket attached to the ceiling. Floor stands attach to the ground via a base plate. Both options are useful, but there are pros and cons associated with each method.

Different Types Of Squirrel Cage Fan

There are different kinds of fans available in market. The most common type of fans we see today is the squirrel cage fan. But there are other types of fans which are more efficient and powerful. So here we discuss different types of squirrel cage fans with its advantages and disadvantages.

Types Of Fans

The main advantage of these fans is that they produce higher volume of air flow compared to others. There are two types of squirrel cage fans namely single speed and variable speed. Single Speed fans run only at one speed whereas Variable Speed fans runs at multiple speeds.

Advantages & Disadvantage

Single Speed fans are cheaper and easy to install. However, they cannot be controlled manually unlike variable speed fans. Also, they are noisy and require frequent maintenance. Whereas Variable Speed fans are expensive and difficult to maintain. They provide greater control over airflow and noise level.


Squirrel cage fans are very simple to install. All you need to do is screw the motor into the base plate and attach the blades onto the shaft. If you wish to change the direction of rotation, simply unscrew the old blade and reattach it to the opposite end of the shaft.


It is recommended to regularly check the bearings and replace them once in six months. Bearings are located inside the housing where dust accumulates quickly. Dust accumulation causes friction between the bearing and the rotor causing heat build-up. Heat build-up reduces efficiency and eventually leads to failure of the fan.

Fan Blades

These fans consist of three parts; the hub, the frame and the blades. Hub is attached to the motor shaft while the frame holds the blades. The blades are fixed to the hub by screws. Each set of blades has four blades. Two of the blades are fixed to the hub while the remaining two rotate freely.

Blade Diameter

This refers to the diameter of the fan blades. Smaller diameter blades create lower pressure and hence consume lesser power. Larger diameter blades create high pressure and thus generate more force.

Airflow Rate

This refers to the amount of air produced per unit of time. Higher airflow rate results in increased cooling capacity.

Noise Level

Fans produce sound due to the action of moving air. Noise levels vary depending upon the design of the fan. High quality fans produce low noise levels. Low quality fans produce loud noises.


High quality fans are expensive because they contain advanced technology. In contrast, low quality fans are inexpensive because they lack features like adjustable speed controls and anti-vibration mounts.
