The ECODRY plus is a newly developed family of dry-compression multi-stage Roots vacuum pumps, which sets new standards in noise reduction. The pumps have been specially designed for use in quiet and clean environments, such as analysis and research laboratories. ECODRY plus provide clean vacuum at maximum pumping speeds of 40 and 55 m³/h while creating the lowest noise level technically possible. They deliver stable vacuum performance for many years without maintenance.
