Positive displacement blowers, oftentimes called “PD blowers”, are utilized to move air through a wide variety of industrial applications such as chemical, agriculture, bulk transport and more.
The selection of positive displacement blowers built by Gardner Denver is second to none and includes:
No matter if your job calls for individual blowers or blower packages, Gardner Denver has the technology you need. From our legendary Sutorbilt name to the rugged and reliable Duroflow and all the way up to the superior Cycloblower, Gardner Denver has the best positive displacement blower selection and technology in the industry.
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
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:
