The Model 701 is an excellent source of clean, dry air for dilution calibrators. 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 -20°C (up to 15 SLPM flow rate) independent of the inlet dewpoint and assists in the removal of other gases, greatly increasing the life of the chemical scrubbers.  The basic Model 701 includes an oil and diaphram free pump plus scrubbers to remove SO2, NO, NO2, O3, NH3, and H2S. Optional high performance scrubbers are available to remove CO and Hydrocarbons.  Inlet air is pulled into the pump and routed through a pre-cooler 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. The Model 701 is an ideal accessory to the Model T700 Series Dilution Calibrators or as a zero air source for analyzers.
