About the series
Features and benefits of the G series
The series at a glance
With capacities of up to 3,000 m³/h and pressure differences of more than 1,000 mbar, the series offers versatile solutions for a wide variety of industrial requirements.
The robust, lightweight blowers stand out for their low noise level, high reliability and long service life. Thanks to 50/60 Hz motors and UL/CSA and IEC/EN certifications, they can be used worldwide. ATEX versions are also available for certain models.
The G series can be speed-controlled with external or integrated frequency inverters and, with an extensive range of accessories including special acoustic enclosures, can be adapted flexibly to different applications.
With the G series, Elmo Rietschle offers a proven range of oil-free side channel vacuum pumps and compressors developed for reliable operation, low maintenance requirements and a long service life. The contact-free side channel principle enables clean and low-wear conveying without oil or lubricants in the conveyed medium. Thanks to its various sizes and versions, the G series offers a flexible solution for numerous vacuum and compressed air applications in industry and material handling.
Oil-free and clean operation
The Elmo Rietschle G series operates completely oil-free and contact-free. This enables clean conveying without oil contamination, and the units are particularly suitable for applications with high air quality requirements.
Robust and low-maintenance
The contact-free side channel principle ensures low wear and reduced maintenance requirements. The robust design enables reliable continuous operation and a long service life.
Versatile in use
The various sizes and versions of the G series allow flexible adaptation to different requirements. It is suitable for both vacuum and pressure applications, for example in the packaging industry, in material handling, in pneumatic conveying and in vacuum lifting.
Operating principle
The Elmo Rietschle G series works on the proven principle of side channel vacuum technology. A contact-free impeller rotates inside the housing and, thanks to the special geometry of the side channel, continuously conveys and compresses the air drawn in. Depending on the version, the units can be of single-stage or multi-stage design and thus achieve different pressure and vacuum performance levels.
The oil-free and contact-free design enables clean operation without oil or lubricants in the conveyed medium. This makes the G series particularly suitable for applications that require reliable and contamination-free generation of vacuum or compressed air.
The robust and low-wear operating principle enables low-maintenance and reliable continuous operation. The G series offers a wide choice of sizes and performance levels and is suitable for numerous industrial applications, including vacuum lifting, pneumatic conveying, packaging, material handling and general vacuum and compressed air applications.
