The Model 701H is an excellent source of high purity zero air for all your process and analytical instrument needs. It is the ideal zero air source for ambient background monitoring applications using highly sensitive analyzers such as the model 100EU, 200EU and 300EU trace gas analyzers. It also may be used as a source of purge air for permeation tube ovens or burner air for FID analyzers. The regenerative, heatless dryer removes water and produces gas with a dewpoint of less than -25°C (dependant on flowrate). and assists in the removal of other gases, greatly increasing the life of the chemical scrubbers. The Model 701H includes a high flow rate oil and diaphragm free pump, scrubbers to remove SO2, NO, NO2, O3 and H2S, and high performance scrubbers to remove CO and Hydrocarbons. The 701H also incorporates a dewpoint sensor that warns if the dewpoint exceeds -16°C. Inlet air is pulled into the pump and routed through a precooler and water trap to remove moisture. The air then passes through the regenerative scrubber for final drying and then to the storage tank. Tank pressure is monitored and maintained at a preset level by cycling the pump automatically as needed, thereby extending both the pump and scrubber life. Outlet air then passes through a filter to assure a clean, dry, analytical zero air supply. A microcontroller cycles the regenerative dryer and water trap valves preventing the pump from starting against full head pressure. Features
