Flow Rate (max.): 2.1 l/min Pressure (max.): 1.2 bar (rel.) Vacuum (max.): 330 mbar (abs.) KNF diaphragm gas pumps transfer or compress gases and vapors and generate a vacuum without contaminating the media. Different options are available for application-specific requirements related to size, motor type, control, voltage, chemical resistance, safety, vibration, noise, and temperature resistance. All pump types offer oil-free operation. Technical Details Flow Rate (max.) 2.1 l/min Pressure (max.) 1.2 bar (rel.) Ultimate Vacuum (max.) 330 mbar (abs.)
