Anywhere high airflow and low vacuum/pressure is required, regenerative blowers are an ideal solution as a properly installed blowers will provide years of service free operation.
 
Regenerative pumps are the ideal solution for moving large volumes of air at lower pressures or vacuums. Regenerative pumps "regenerate" air molecules through a non-positive displacement method to create vacuum or pressure.
