When it comes to blowers, there are many different types. Blowers induce a gas flow for many applications including exhausting, cooling and ventilating. If you’re looking at different blower manufacturers wondering which blower might work best for you, keep in mind what you’re using it for, what type of blower it is, design and dimensions. Different types of blowers include:
- Centrifugal blowers: When it comes to a centrifugal fan vs axial fan, there are some noticeable differences. Centrifugal fans use high speed blades to add velocity to air or other gases. They displace air radially, changing the direction (usually by 90 degrees) of the airflow. Centrifugal blowers offer several different types of blades including backward and forward curved and radial. These blowers are usually powered by electric motors, but can also be used with drive motors.
This guide offers an in-depth look at choosing the right centrifugal fan or blower.
- Regenerative blowers: These blowers are considered contact-free machines; they are virtually maintenance free and can operate up to 40,000 hours without needing to be serviced. They are a good choice for moving bigger amounts of air at lower pressures. As their name suggests, regenerative blowers regenerate air through non-positive displacement to create pressure.

- Air knife blowers: The number one most common use of air knives is to contain or remove free-standing materials from the surface of a material. This comes in handy for restaurants, as according to the CDC, one in six Americans each year gets sick from consuming contaminated food or beverages. An air knife blower system works as pressurized air fires through a series of holes, which creates an impact velocity onto the surface where the air is directed. Today, blower manufacturers have perfected designs first used in the 50s and 60s and typical air knife blower systems are made in a teardrop shape, which allows them to function more efficiently.
Air knife blowers are common products among blower manufacturers and a quick online search reveals a wealth of options to choose from.
- Enhanced durability
- Easy to maintain
- Available in multiple sizes
- Ability to restrict overloading
- First rate energy efficiency
- Energy efficiency
- Best suited for general purpose applications
- Great for moving air from one place to another
- Great for cooling confined spaces such as a work space
- Commonly used in vending machines to provide cooling for those enclosed spaces
