The ECODRY plus is a 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 25 to 55 m³/h while creating  low noise levels. They deliver stable vacuum performance for many years without maintenance.

The pumps are based on the multi-stage Roots pumping principle with two contactless rotating rotors turning in opposite direction. Through their rotation the gas is moved from the inlet to the exhaust. By the effect of multiple pumping stages the gas is compressed from medium vacuum range to ambient pressure.

The products are standing out due to the following features:

• Quiet – With the integrated acoustic insulation and silencer the noise level of these pumps is lower than 52 dB(A) - quieter than a normal conversation.

• Clean – With an oil-free suction chamber and wear-free operation, neither oil vapors nor particles are contaminating the vacuum chamber or the environment.

• Maintenance-free – Changing oil or seals is not required - the pumps deliver stable vacuum performance for many years without maintenance.

• Easy to use – The pumps are compact, powered by regular single-phase sockets, air-cooled and easy to reposition by integrated wheels.
