What is Positive Displacement Blower?

A positive displacement blower is a type of pump used to move gas or air by trapping a fixed amount of fluid in an enclosed space and displacing it into a discharge pipe. This type of blower operates by trapping a certain volume of gas or air in a chamber and then forcing it out through a discharge port. Positive displacement blowers are commonly used in applications requiring a constant flow rate and are often used in industries such as wastewater treatment, pneumatic conveying, and ventilation systems.

What is the role of a positive displacement blower?

The role of a positive displacement blower is to move gas or air from one place to another by creating a low-pressure zone that allows for the intake of gas or air, then compressing it, and finally discharging it at a higher pressure. Positive displacement blowers are commonly used in applications that require a constant flow rate and relatively low pressures, such as pneumatic conveying, wastewater treatment, vacuum systems, aeration, and ventilation. They can also be used for specialized applications, such as in the oil and gas industry for transferring gases and liquids, as well as in industrial processing for the handling of bulk materials. Overall, the key role of the positive displacement blower is to provide a reliable and efficient means of moving gas or air in a variety of industrial and commercial applications.
