Positive displacement blowers, also called PD or rotary engine blowers, are pieces of machinery employed to move air or fuel for various purposes. The air is generally propelled from an exhaust tube to a nozzle, directed to the desired location where it is bound to carry the required amount of weight to complete the task.
A positive displacement engine, also known as a rotary engine, has been around for decades and is a popular option for use in industries that require heavy machinery for their operations. The force applied by this machinery is required for moving massive objects.
A negative displacement machine, also referred to as a rotor engine, doesn’t have a nozzle. Instead, it’s driven by a fan or rotor set to push or pull air through the cylinder. The air can be either directed into the cylinder or blown out of the cylinder, depending on the application.
There are different types of positive displacement blowers, and they differ in terms of the amount of power they produce and how fast they operate. There’s also a wide range of sizes available— from small to medium. If you’re looking for one to utilize at home or in your business, you can contact companies that provide numerous engineering services such as Northwest Flow Technologies.
