The Zero air generator is a highly compatible device designed for use with Chromatotec products. It is an ideal solution for generating air free of impurities, which can be used for verification and maintenance of chromatographs or other types of high precision monitoring equipment. The generator provides clean air with a total hydrocarbon concentration of less than 1 ppb, which makes it ideal for use with high-precision equipment. It has a maximum flow rate of 1 L/min in discontinuous mode, and a low noise level of less than 55 dB (A). The generator is equipped with a 10-liter reservoir that operates at 7 bars, and it can provide zero air to all or some of the components of the monitoring equipment such as FID detectors, pneumatic valves, Peltier cooler, Calibration permeation tubes and MEDOR traction gas.
