Squirrel Cage Blower How It Works

How a Squirrel Cage Blower Works squirrel cage blower how it works

If you’re wondering how a squirrel cage blower works, then you’re in the right place. This article will walk you through what to look for when choosing one. Learn how the impeller works, the differences between centrifugal and axial fans, and what type of pressure it can handle. Then, use the tips from this article to find a squirrel cage blower that meets your needs. You’ll be glad you did!

115V or 230V motor

There are two main types of motors for squirrel cage blowers: 115V and 230V. Choosing the right motor for your squirrel cage blower will depend on its purpose and your needs. Both of these types of motors can be used with the same model of squirrel cage blower, but choosing the right one will determine the efficiency of your system. Listed below are some benefits of using a 230V motor for your squirrel cage blower.

Identify the direction of rotation of your motor before buying it. Modern electric motors are tagged to indicate whether or not they can reverse direction. If they do not, simply reverse the direction of rotation of the shaft. You can also look for a reversible motor that includes the CCW end of the rotation shaft. A non-reversible motor can be flipped by swapping the starting winding wires.

Centrifugal fan

A centrifugal fan for a squirrel cage blower is a simple and inexpensive way to provide airflow for a variety of applications. These fans are commonly used in industrial settings, where they are safer and more effective than axial fans. However, in hazardous environments, they may not be as effective and might degrade more quickly. In such cases, a squirrel cage blower may be a better option.

A centrifugal fan for a squirrel cage blower is similar to a hamster wheel, and uses kinetic energy to increase air velocity and capacity. The difference between a centrifugal fan and a positive displacement fan is the way they direct air. These fans have more powerful motors and are more energy-efficient. If you’re looking for a squirrel cage blower, consider investing in a Lasko Pivot-Pro model. It features an ETL-listed circuit breaker and reset button, as well as patented Blue Plug safety fuse technology.

Blade configurations

A squirrel cage blower’s blade configuration determines the airflow. The higher the pitch, the more air it will move. To achieve maximum air flow, the pitch should be between 4,000 and 5,000 RPM, depending on the size of the cage. Also, consider the angle of attack of the fan blades. If the angle is too high, the fan will not produce enough airflow and will eventually fail.

The squirrel cage blower has several different configurations. A single or double-inlet design can reduce noise. Double-inlet systems are best for confined areas. Some of these blowers feature tangential crossflow or backward curve designs. In addition, they are tabbed riveted for durability. The blades of a squirrel cage blower rotate CW or CCW to create different airflow patterns.

Pressure capability

Unlike other types of fans, a squirrel cage blower has adjustable output. Its low noise and high efficiency make them a popular choice in environmental chambers. Other features that make them ideal for these applications include adjustable output and a variable-speed motor. A squirrel cage blower’s impeller axle is steered by bearings, which help reduce resistance and increase efficiency. Bearings must be properly lubricated and designed to minimize friction to maintain a high level of efficiency.

To increase the pressure capability of a squirrel cage blower, the impeller must be shaped like a half-cone. Cho et al. employed particle image velocimetry to study the impeller’s flow status. They found that this shape improved efficiency and pressure capabilities. This study has a number of implications for the design of squirrel cage blowers. Ultimately, a squirrel cage blower should be able to achieve its intended purpose, but determining the precise pressure capacity is crucial.


If you notice a slow air conditioner operation, you might have a squirrel cage blocking the air flow. The easiest way to fix this problem is to replace the squirrel cage blower. Before you attempt to replace the squirrel cage blower, you should unplug the unit from its power source and unscrew two screws at the back of the motor shaft. Read this article for tips on how to remove the squirrel cage blower.

The squirrel cage blower is located inside the air handler assembly. The device collects air and directs it to the ducts. Rust and other defects can prevent the squirrel cage blower from performing its job, but a replacement will solve the problem. Moreover, the squeaking noise will be solved. If you are not comfortable installing the squirrel cage blower yourself, here are some tips to help you.
