About the series
Features and benefits of the C-VLR series
The series at a glance
The Elmo Rietschle C-VLR ZEPHYRS series comprises powerful, dry and contact-free vacuum pumps with pumping speeds of 60 to 1,000 m³/h and a maximum continuous vacuum of down to 50 mbar(abs.). The efficient, air-cooled design allows reliable operation without an additional cooling medium.
The pumps offer high efficiency, low noise levels and service costs, long operating times and a compact design. Frequency inverters and ATEX-compliant versions are available as options.
The LUV version extends the series with smaller models of 60, 100 and 150 m³/h for applications such as packaging, degassing and drying. An optional ProCoat dry-film coating provides additional corrosion protection and is particularly suitable for humid processes.
With the C-VLR series, Elmo Rietschle offers a powerful range of dry-running claw vacuum pumps that was developed for clean operation, reliable vacuum generation and low maintenance. The contact-free claw principle allows oil-free compression without lubricants in the pumped medium and ensures low-wear operation. Thanks to the robust construction and efficient technology, the C-VLR series offers a reliable solution for numerous industrial vacuum applications.
Dry and oil-free
The Elmo Rietschle C-VLR series works completely dry and oil-free. As a result, the pumped medium remains free of oil contamination, which allows clean and reliable vacuum operation.
Contact-free claw principle
The counter-rotating claws work without contact, which minimises mechanical wear and reduces maintenance requirements. This supports reliable continuous operation and a long service life.
Powerful and versatile
The C-VLR series offers efficient vacuum generation and is available in various performance sizes. It is suitable for numerous industrial applications that require clean vacuum, high operational reliability and low-maintenance operation.
Operating principle
The Elmo Rietschle C-VLR series works on the principle of dry-running claw vacuum technology. Two counter-rotating claws move without contact inside the pump housing and create continuously changing working chambers. The rotary movement of the claws compresses the air drawn in, which is then discharged through the outlet.
As the C-VLR series runs dry and oil-free, the pumped medium does not come into contact with oil or lubricants in the compression chamber. The technology therefore allows clean and contamination-free vacuum generation and is particularly suitable for demanding industrial processes.
The contact-free claw principle ensures low wear and reduces maintenance requirements. The robust construction allows reliable continuous operation and a long service life combined with efficient vacuum generation.
The C-VLR series is suitable for numerous industrial applications that call for dry, oil-free vacuum, high operational reliability and low-maintenance operation.
