Galvanized steel, aluminum, aluminized steel, stainless steel. CW or CCW rotation. Basic Types of Centrifugal Fans. Below are the six most common types of centrifugal fans, each with a unique blade configuration. Forward Curved Fan – Also known as a squirrel cage fan due to the wheel type, this fan’s impeller is forward and somewhat small. In addition, the blades curve in the same direction as the rotation of the wheel. The propeller or axial flow fan propels the air in an axial direction (Figure 1a) with a swirling tangential motion created by the rotating impeller blades. In a centrifugal fan the air enters the impeller axially and is accelerated by the blades and discharged radi- ally (Figure 1b).Sep 08, 2017 · Blower / squirrel cage fans are same design and are centrifugal fans. The fans we normally use are axial fans. While blower fans make way more pressure and can overcome much more resistance, for our applications they make way too much pressure to airflow volume .. like 10-20 times as much pressure as needed .. even for extreme resistance like CLC radiators. May 26, 2002 · Different types of fan/blower designs have different shaped curves. The types of designs are forward curved (FC) centrifugal (this is the very common squirrel cage fan), backward inclined (BI), BI air foil, vaneaxial and propeller. The most common types that are used in residential applications are FC and propeller. For static pressure, run the fan blowing into a closed box with a pressure guage on it. Keep increasing fan speed until the pressure drops instead of rises. Check the current and rpm of the motor and compare it to the motors capacity/rating. Change motors (larger if fan doesn't top out on static pressure) if necessary.Vibration occurs during fan operation and may have many causes, one of which could be imbalance. Other causes of vibration include mechanical looseness, coupling misalignment, defective bearings, insufficient flatness of bearing mounting surfaces, rotor cracks, driver vibration, and V-belt slippage.

A centrifugal fan can be referred to as a blower fan, squirrel fan, squirrel cage fan, squirrel cage blower, or squirrel cage blower fan. Regardless of what you call it, centrifugal fans get their name from the output of air using centrifugal force. As air is extracted perpendicularly through the blower, it is spun out using centrifugal force. The air enters the fan wheel through the housing inlet, turns 90 degrees and is accelerated radially and exits the fan housing. Centrifugal fans are typically used for lower flows and higher pressures. Axial fans use a propeller, having two or more blades, to move air in an axial direction through a cylindrical housing or formed orifice panel.Different types of fan/blower designs have different shaped curves. The types of designs are forward curved (FC) centrifugal (this is the very common squirrel cage fan), backward inclined (BI), BI air foil, vaneaxial and propeller.

In addition, the blades curve in the same direction as the rotation of the wheel. Squirrel Cage Fans. The squirrel cage fans are the 'old fashioned' way to move air before the centrifugal fans came out. If you mount them "free-flowing" so they don't have any restriction (like carbon filters, reflectors, or any length of ducting) they work OK. They are inexpensive, and they do have some good applications. Centrifugal Fans The air enters the fan wheel through the housing inlet, turns 90 degrees and is accelerated radially and exits the fan housing.

Forward Curved Fan – Also known as a squirrel cage fan due to the wheel type, this fan’s impeller is forward and somewhat small. In addition, the blades curve in the same direction as the rotation of the wheel. Centrifugal fans blow the gas radially outwards from the axis of the impeller. They are also known as Squirrel cage fans due similarity in appearance to the exercise cage used for pet squirrels. Gas sucked in from the cavity present in the centre of the impeller is driven outwards by the centrifugal force acting on the gas due to rotational motion.Centrifugal fans are also referred to as blower fans or "squirrel cage" fans because the fan wheel resembles a hamster wheel. The impeller of a centrifugal fan consists of a casing with a central shaft surrounded by blades that form a spiral. As the impeller rotates, the air moves in a perpendicular motion from the shaft to the fan casing ...A very common type of centrifugal fan, typically referred to as a centrifugal blower, uses a squirrel cage type wheel with many FC blades ( Figure 1 ). The blades are shallow with a substantial curvature in the direction of rotation that results in a higher blade tip speed than a BC blade.Centrifugal fans are sometimes called "squirrel cage" fans because of the shape of the impeller wheel. They are widely used in HVAC/R applications to distribute conditioned air through ductwork. There are several types of centrifugal fans, categorized according to how the blades are fixed to the impeller. The three most common impeller ...Forward curved centrifugal STRIP blower wheels: Also known as squirrel cage blower wheels. Diameter from 1.50″ to 9.45″. Single or double inlet.
