Is a blower a centrifugal fan?
Centrifugal blowers, or fans, are among the most efficient and versatile pieces of air moving equipment. The scroll housing in a centrifugal fan accelerates the air and changes the direction of the airflow twice, a full 90 degree, before leaving the housing.
What are centrifugal fans used for?
What are centrifugal fans used for? A centrifugal fan is typically used for residential applications to move air through a duct in your home. Think of your air conditioning system, furnace, or range hood duct. You also might see these in commercial environments like your car wash.
What types of centrifugal fans are available?
There are three types of centrifugal fans determined by the type of fan blades:
- forward inclined blades,
- backward inclined blades, and.
- straight radial blades.
Is blower and fan the same?
Generally, fans are devices that move larger amounts of a gas with a very low increase in pressure. The term blower is sometimes used interchangeably with fan. In general, a blower has a slightly higher pressure rise than a fan: from 1.11 to 1.2.
Where are blowers used?
They are mainly used in many cooling and drying applications. Centrifugal blowers are routinely used for applications such as dust control, combustion air supplies, on cooling, drying systems, for fluid bed aerators with air conveyor systems etc.
Which type of motor is preferred for blowers or centrifugal fans?
For blower applications, the most common motors are 2-pole (3600 rpm), 4 poles (1800 rpm), and 6-pole (1200 rpm). The most preferred motor for the blower is squirrel cage induction motor, synchronous motor, DC shunt Motor, Split-phase motor.
Which type of blower has maximum efficiency?
Among centrifugal fan designs, aerofoil designs provide the highest efficiency (upto 10% higher than backward curved blades), but their use is limited to clean, dust-free air. Axial-flow fans produce lower pressure than centrifugal fans, and exhibit a dip in pressure before reaching the peak pressure point.

How does a centrifugal blower work?
Centrifugal type blower uses the centrifugal force generated by a rotating disk, with blades mounted at right angles to the disk, to impart movement to the air or gas and increase its pressure. The assembly of the hub, disk and blades is known as the fan wheel, and often includes other components with aerodynamic or structural functions.
What is an industrial fan and industrial blower?
Industrial fan and Industrial blower are machines whose primary function is to provide and accommodate a large flow of air or gas to various parts of a building or other structures. This is achieved by rotating a number of blades, connected to a hub and shaft, and driven by a motor or turbine.
