Edwards vacuum pump series nXDS is a Scroll Pump vacuum pump suitable for applications that require high cleanliness. Because without oil The vacuum can be adjusted in the range of 0.02 mbar without noise because it has a working noise level of only 52 dB (A) only. Suitable for use in research laboratories and scientific equipment.
