Centrifugal Blowers

Centrifugal blowers are one of the most popular types of blowers that are currently being used in the Heating, Ventilation and Air Conditioning industry today. Because these types of equipment are so widely circulated, they are priced moderately and a wide array of replacement parts and accessories are easily accessible.

TelcoComponents, a division of Telco Intercontinental Corporation, offers a diverse assortment of high quality centrifugal blowers with a forward curved blade design. With high quality products, customizable solutions and excellent customer relations, Telco is your one-stop shop for fans and blowers with centrifugal force capabilities.

How Does a Centrifugal Blower Work?

Centrifugal blowers or fans typically are comprised of four main components: a motor, a fan wheel, and housing.

A centrifugal blower makes use of rotating impellers that are attached to the fan wheel, which is set within the exterior housing. The blades catch air while spinning and have the ability to “throw” the air out of the outlet at roughly a 90 degree angle from which the air was taken in through the inlet.

The electric motor is either attached directly to the fan wheel, which is called direct drive, or by a belt or gear mechanism, which can be customized and allows for the ability to change the speed of the fan wheel.

The fan wheel component of a centrifugal blower can also have different styles of blades, with each style being utilized to enhance a certain aspect or to achieve a desired performance.

Once the air or gas is taken into the inlet of the blower, the motor spins the fan wheel and the air is diverted, typically at about a 90 degree angle, and sent through the outlet at a specific volume and velocity.

High Quality, Versatile Volume Blowers

With a range of up to 1,200 cfm our centrifugal blower has incredible Cubic Feet per Minute capacity. A blower with centrifugal force can be used in a wide variety of settings and scenarios, including:

  • Residential and commercial HVAC use
  • Industrial equipment and technologies
  • Food equipment and applications
  • Medical applications and equipment

Customizable Pressure Blowers

One component of a centrifugal blower that can drastically impact its performance is the direction of the blades on the fan wheel. A centrifugal blower typically has three different fan blade styles: forward curved, backward curved, and radial basic. The low noise, forward curved blades, which are angled in the direction of the fan wheel’s rotation, are usually used for low pressure applications that require a high volume of output, such as hot air dispersion units.

Backward curved blades, which are angled in the opposite direction of a fan wheel’s rotation, are used for higher pressure and lower volume applications, such as turbo chargers and air compressors, and are an efficient design.

A radial basic set up is one where the blades protrude perpendicularly to the rotor and is more similar to the design of a traditional fan. A radial design typically is noisier, but provides a pressure and volume ratio that is a balance between the forward and backward curved blade designs described above.
