Side Channel Blowers

Elmo Rietschle side channel blowers, also known as G-Series blowers, are high-performance vacuum and pressure units designed for reliability, efficiency, and flexibility. These blowers have been refined over decades to meet the demanding requirements of industrial, medical, and environmental applications. With low noise levels, robust design, and long service intervals, they provide consistent operation with minimal maintenance, making them an ideal choice for a wide range of industries.

Reliable and Built-to-Last

Side channel blower technology has proven to be remarkably reliable. Many models, such as the G-BH100, G-BH1, G-BH7, and G-BH8, can operate for up to 20,000 hours without maintenance downtime. Meanwhile, the G-BH2 model can operate up to 40,000 hours, providing exceptional cost efficiency and continuity of service. Furthermore, their lightweight and compact construction makes installation straightforward while still providing industrial-grade robustness.

These blowers have been designed for worldwide use, with certifications including UL, CSA, IEC, and EN standards. Selected models, such as the G-BH1 and G-BH7, are also ATEX 94/9 EG approved, enabling safe operation in potentially explosive environments. In addition, all G-BH models can be equipped with adjustable speed controls via external or integral frequency converters, allowing energy-efficient operation that can be fine-tuned to specific applications.

Wide Performance Range

Elmo Rietschle G-Series side channel blowers cover an extensive performance range. Volume flows vary from 1 to 2,750 m³/hr, and ultimate vacuum levels can reach 550 mbar (abs), while ultimate pressure reaches up to 1,100 mbarg. This broad range ensures these blowers can handle both small-scale and high-capacity processes, offering flexible solutions for diverse applications.

The side channel design enables continuous, oil-free operation without internal lubrication. This ensures the transported medium remains uncontaminated and reduces maintenance costs over the life of the blower. Furthermore, the low noise operation improves workplace conditions, particularly in manufacturing and laboratory environments where quiet operation is essential.
