What is a Positive Displacement Blower

Positive displacement blowers are utilized to move either gas or air through a wide variety of industrial applications such as chemical, agriculture, bulk transport, and more.

No matter if your job calls for individual blowers or blower packages, Gardner Denver has the technology you need.

Common Types of Positive Displacement Blowers

The different types of positive displacement blowers may differ in their construction or operation but all are designed to assist with the movement of materials. PD blowers simply trap and then discharge air to propel materials through pipe or hose which makes bulk transport a quicker and more efficient operation.

• Straight Bi-Lobe Blowers - employ two figure eight rotors (or lobes) that rotate
• Straight Tri-Lobe Blowers - utilizes straight rotors with three lobe design, less noisy and lower pulsation compared to bi-lobe
• Twisted Tri-Lobe Blowers - has helical tri-lobe rotors, smoother pulse operation to extend the life of the bearings
• Helical Screw Blowers - helical rotors with unique screw design for superior energy savings
• Blower Packages - Plug and play simplifies installation and enclosures cuts down on noise levels

Description of Positive Displacement Blower Operation

Positive displacement blowers discharge air out into a pipe or hose in order to move materials. Rotors revolve and air is pulled into the inlet port, air is forced into tight areas between the rotors and casing then is forced to the outlet pipe (or hose). The term “positive displacement” comes from the fact that the volume of air doesn’t change within the blower but is displaced from one end to the other during operation.
