The ECODRY plus pumps are a newly developed family of dry-compressing multi-stage Roots vacuum pumps that score points with their noise reduction. The pumps have been specifically designed to be used in quiet and clean environments, such as analysis or research laboratories. The ECODRY plus create a clean vacuum with maximum suction speeds of 40 and 55 m³/h and produce a very low noise level. They provide stable operation for many years without maintenance.
The pumps work according to the multi-stage Roots pumping principle with two non-contact rotating rotors that rotate in opposite directions. As they rotate, the gas is conveyed from the inlet towards the outlet. The gas is compressed from the fine vacuum range up to ambient pressure by means of several pump stages connected in series.
The product range is characterized by the following features:
Quiet - Due to the integrated noise insulation and the silencer, the sound level of the pumps is lower than 52 dB(A) - and therefore quieter than a normal conversation. Clean - Since the suction chamber is oil-free and there is no abrasion, neither oil vapors nor dust particles are created that contaminate the vacuum chamber and the surrounding area. Maintenance-free – oil changes or seal replacements are not necessary - the pumps work stably for many years without maintenance. Easy to set up - The pumps are compact, powered by standard AC sockets, air cooled and easy to move using the integrated rollers.
