Side channel blowers are made with an emphasis on efficiency, quiet operation, and oil-free performance in order to satisfy continuous airflow requirements. Stable pressure generation is made possible by precisely balanced impellers and stiff housings, which reduce vibration and heat accumulation. The blowers are appropriate for continuous-duty applications because of their contactless operating principle, which guarantees low wear. Pneumatic conveying, wastewater aeration, packaging machinery, printing equipment, and industrial vacuum or pressure systems—of which there are several capacity and pressure variations—are common applications.
