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.
Some of the most common industries that utilize positive displacement blowers include:
Oil & Gas
Pulp & Paper
