Selecting the Best Blower for You

There are three main types of blowers and these are; positive displacement lobe, centrifugal, and high efficiency and depending on the size of the application you can tell which blower is right for your operation. For smaller applications the positive displacement lobe blowers are the right option as their output and pressure can be directly governed by the speed in which you run them at. Centrifugal blowers are used in medium or large wastewater treatment applications. These blowers usually run at a constant speed, but the airflow output can be throttled by the inlet valve. For these small to medium sized operations a Gardner Denver IQ blower package would be the right call, and Best Aire is a certified representative for Gardner Denver.

For the applications that require a large volume of air, you are going to want to use the last kind of blower that was listed earlier and that is the high efficiency blower. These blowers are ideal as they use magnetic bearing that make it super-fast and allow for the fastest payback on investment. When determining the correct blower size, the most important factors to consider are the load, flow, tank configurations, and the specific application you are considering. Once you have selecting your blower you may consider adding a variable frequency device (VFD) to give you better insight and control over your machine.
