The regenerative blower also called ring blower or side channel blower.
The air is sucked into the impeller and compressed to output a high-pressure airflow, which allows this blower to be dual-use(inhale and blow). And the air it outputs is very clean, because it is purely electric, which means it is ECO-friendly. Environmental protection is the current trend, and what we want to do.
The high loss of the entire regenerative blower is only the bearing, which is used to support the impeller rotation, and the other parts of the blower will not produce friction. Good bearings mean the fans are almost maintenance-free, it will make your after-sales easy.
