What is a squirrel cage in a furnace?
A squirrel cage furnace blower is a type of fans that is found in a furnace. It moves air through the furnace system to heat your house. Squirrel cage furnace blowers fit under the umbrella of centrifugal fans because they are shaped to force air away from the center of the fan.
Which direction does a squirrel cage fan turn?
The fan wheel rotates clockwise or counter-clockwise, with the small forward-curved blades scooping the airflow and slinging it out as the wheel rotates. It is designed to move high-volume airflow with very little static pressure.
What is a fan shaft?
In industrial settings, a fan shaft is a type of ventilation shaft used for maintaining air quality in an enclosed space, like a mine or other subterranean installation. A fan is mounted in the shaft in order to increase air flow as well as to move the flow in a certain direction.
Where is the blower compartment on a furnace?
One of the hardest-working parts of your home’s furnace is the blower motor. In a gas forced air furnace, it’s located in a box at the base of the furnace next to the air filter, where it draws return air through the filter.
What are squirrel fans used for?
A squirrel cage blower, also known as a centrifugal blower, is used to move air and gases in a variety of applications. This equipment is so named since its construction looks similar to that of a hamster wheel.
Is the blower motor in the furnace?
The blower motor is the component in a central HVAC system that consumes the most energy. If you already have a variable speed blower motor in your furnace, and the motor is not clogged with debris, the motor may be wearing down and approaching end of life.
Where is the blower located on a furnace?
The blower fan motor is normally supported on rails near the bottom of the furnace. Since the motor power wires are connected to a control board that is often located in an upper compartment, two access panels may need to be removed.
How do you open an oscillating fan?

How do you know the rotation of a blower wheel?
Use the hands of a clock for reference. If they’re tilted toward Clockwise Direction, as in the picture to the left, then you have a Clockwise Forward Curve Blower Wheel. That’s the direction the blower wheel will spin or operate, and that’s the direction of the intended air flow, as well.
How do I know if my blower is CW or CCW?
Wheel Diameter: Measure the diameter of the blower wheel – the longest distance from one side of the ring to the other side. From the appropriate perspective described above you will see the wheel is spinning clockwise (CW) or counter clockwise (CCW).
Why do they call it a squirrel cage?
Squirrel cage motors are a subclass of induction motors, which harness electromagnetism to generate motion. They are so-called “squirrel cage” motors because the shape of their rotor – the inner component connected to the output shaft – looks like a cage.
What kind of Freon is used in central air conditioning?
R22 is what is commonly known as Freon, and has been used as a central air conditioning system refrigerant for decades.
Is a blower motor and fan motor the same?
Unlike the condenser fan motor, the blower motor is located indoors. It’s the component that blows cool air through the ducts and into different parts of your home. … While a variable-speed or high velocity motor can adjust its speed to produce different levels of airflow.
