Types of Air Blowers
Air blowers are electro-mechanical or mechanical devices which are used to induce gas flow by way of process stacks, electronics chassis, ducting, etc whenever you need the flow for cooling, exhausting,conveying, aspirating, ventilating, and so on.
Types of Air Blowers
Largely, if you go out shopping for air blowers onlineor from a store, you’ll get to know that there are two key types of blowers.
Centrifugal Blowers
Centrifugal air blowers make use of high speed blades or impellers to impart velocity to air as well as the other gases. These can be either single or multi-stage units. Like fans, the centrifugal blowers also offer a variety of blade orientations such as forward curved, backward curved and radical. Blowers can be either variable or multi speed units. These are usually driven by electric motors often via a sheave arrangement and belt.

However, there are certain centrifugal blowers which are directly coupled to drive motors. You can easily alter the fan speed to change the flow rates by using variable speed drives,resizing sheaves, etc. However, dampers are even more common when it comes to adjusting the flow. The fan affinity law determines that a percent reduction in speed of the fan will lead to a reduction in the flow.
Positive Displacement Blowers
Another air blower that you can buy is the positive displacement blower. This is very similar to positive displacement pumps when it comes to their functioning. They make use of mechanical means in order to squeeze fluid and thereby accentuate velocity and/or pressure. On the other hand, the centrifugal designs impart pressure and velocity to media by flinging them outwards by use of impellers. In the positive displacement blowers, the rotary lobe or the roots is common. This uses two counter rotating lobed rotors in order to move the fluid through the blower.
The entire thing is similar to the manner in which a gear pump moves oil or other types of liquids. These blowers are usually driven by direct-coupled electric motors however, these can also be driven by hydraulic motors,gas engines, etc in unusual circumstances.
Based on the features, functions, performance, models and brands, the air blower pricemay vary. Depending upon your budget or requirement, you can opt for an air blower, which fulfils all your needs.
Summary
Air blowers are one of the most important tools, which are used in homes and industries. To learn about the types of air blowers that can be bought by you, you can read this article and be informed on the subject.
