Olympias Side Channel Blower

Olympias 1 stage and Olympias 3 stage Blowers

Side Channel Blowers are ideal for moving large volumes of air as a compressor or vacuum pump. When operating conditions fall within a side channel blowers range, they are the most cost effective method of moving air.
Olympias Blowers can operate continuously at their stated performance curve. Among the other major benefits of a side channel blower, is its lack of maintenance requirements. They are oil-less and will not contaminate the application with oil or carbon dust. These blowers have a non pulsating flow and a low level of noise. A side channel blower is also often known as a regenerative blower or an exhauster.

We offer a 2 year warranty (conditions apply).
