Download BrochureCommon Types of Positive Displacement Blowers
While the construction and operation of positive displacement blowers can vary, they all serve the same purpose: facilitating the movement of materials. PD blowers operate by trapping and discharging air to propel materials through pipes or hoses, making bulk transport faster and more efficient.
- Straight Bi-Lobe Blowers: Utilise two figure-eight rotors (or lobes) that rotate to create airflow.
- Straight Tri-Lobe Blowers: When compared to bi-lobe blowers, these units have straight rotors with a three-lobe design, delivering reduced noise and lower pulsation.
- Twisted Tri-Lobe Blowers: Utilise helical tri-lobe rotors for smoother pulse operation, extending the bearings’ life.
- Helical Screw Blowers: These blowers use helical rotors with a unique screw design, providing greatly improved energy savings.
- Blower Packages: Designed for easy installation, these plug-and-play systems include enclosures that significantly reduce noise levels.
Positive Displacement Blower Operation
Positive displacement blowers expel air into pipes or hoses to facilitate material movement. During operation, the rotors rotate, drawing air into the inlet port. This air is compressed in tight spaces between the rotors and the casing before being discharged through the outlet. The term “positive displacement” indicates that the air volume remains constant within the blower but is moved from one end to the other during operation.
