The Leybold ECODRY 35 plus is a compact, oil-free multistage Roots vacuum pump designed for clean laboratory, analytical and research applications. Delivering up to 35 m³/h (approximately 21 CFM) of pumping speed and reaching an ultimate pressure of approximately 0.01 mbar, the ECODRY 35 plus provides high-performance dry vacuum in a remarkably compact package.

The 100–127/200–240 V, 50/60 Hz, single-phase power configuration provides exceptional flexibility for laboratories, OEM equipment manufacturers and research facilities worldwide. With approximately 29 kg of weight, forced-air cooling, DN25 ISO-KF connections and noise levels around 52 dB(A), the ECODRY 35 plus is easy to integrate into laboratory and analytical systems without the noise, size or maintenance associated with larger industrial vacuum pumps.

Its oil-free multistage Roots technology makes the ECODRY 35 plus particularly well suited as a backing pump for turbomolecular pumps, electron microscopes, mass spectrometers and other analytical instruments where oil contamination must be avoided. The oil-free pumping chamber eliminates routine vacuum-oil changes and provides a clean primary vacuum environment.

The ECODRY 35 plus is intended for clean-duty applications rather than hazardous, corrosive or highly reactive process gases. For demanding industrial processes, the VARODRY family provides a more appropriate dry-pump platform.

For laboratories and analytical instruments that need clean, quiet and compact dry vacuum, the ECODRY 35 plus delivers industrial-quality performance without the industrial-sized footprint.
