Regenerative Blower FAQ
- How is a regenerative blower used?
Regenerative blowers are often used in chemical or environmental processes, as well as in lifting, packaging, and conveying applications. They efficiently remove dust and smoke, provide soil vapor extraction, and are also effective sewage aeration. - Is the regenerative blower more expensive than other blower options?
The answer to this question can vary depending on the application. Regenerative blowers can lower maintenance cost compared to other blowers because they do not require oil, and are capable of handling small amounts of material or vapor that might be problematic for other technologies. - Can you describe the device concept of a regenerative blower?
As the impeller blades pass the inlet port, it draws air or other gases into the blower. Then the impeller blades accelerate the air outward and forward through centrifugal force. The regenerative principle happens as the air is turned back by the annular shaped housing to the base of the following blades, where it is again forced outward. Each regeneration increases pressure to the air. - What key components make regenerative blowers better/worse than other blowers?
Characteristics that make regenerative blowers preferable to other options include minimum maintenance requirements, no friction between blower impellers and blower housing, much quieter operation.Regenerative blowers can also offer greater efficiency with a longer service life, when properly maintained. They are ideal for low-pressure applications where minimal noise generation is preferred.
