Regenerative blowers, also called ring compressors, pull air into the blower's inlet port using impeller blades, which then accelerate the air outward and forward. These blowers move high volumes of air through a pipe or hose to a specific location. They operate at lower pressure or vacuum levels than positive displacement blowers, which reduces noise and vibration. These blowers are installed into systems to provide pressure and vacuum for pneumatic conveying, aeration in wastewater and fish farms, as well as air quality monitoring applications.
