Regenerative blowers are the ideal solution for moving large volumes of air at lower pressures or vacuums. Unlike positive displacement compressors and vacuum pumps, regenerative blowers “regenerate” air molecules through a non-positive displacement method to create vacuum or pressure. In the world of air handling equipment, regenerative blowers are probably the least understood of today’s technologies, but when system parameters fall within the range of a regenerative blower, it can be the most cost effective method for producing pressure or vacuum.
