1. 8 2 06712B DCN5875 Teledyne API M701H High Performance Zero Air Generator A Primer on Electro Static Discharge Potentially damaging electro static discharges can occur e Any time a charged surface including the human body discharges to a device Even simple contact of a finger to the leads of a sensitive device or assembly can allow enough discharge to cause damage A similar discharge can occur from a charged conductive object such as a metallic tool or fixture e When static charges accumulated on a sensitive device discharges from the device to another surface such as packaging materials work surfaces machine surfaces or other device In some cases charged device discharges can be the most destructive A typical example of this 1s the simple act of installing an electronic assembly into the connector or wiring harness of the equipment in which it 1s to function If the assembly is carrying a static charge as it is connected to ground a discharge will occur e Whenever a sensitive device 15 moved into the field of an existing electro static field a charge may be induced on the device in effect discharging the field onto the device If the device is then momentarily grounded while within the electrostatic field or removed from the region of the electrostatic field and grounded somewhere else a second discharge will occur as the charge is transferred from the device to ground 8 3 Common Myths Abou2. 8 2 06712B DCN5875 vii This page intentionally left blank viii 06712B DCN5875 1 INTRODUCTION 1 1 Preface Teledyne API is pleased that you have purchased the Model 701H Zero Air System The M701H 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 dew point of less than 40 C up to 30 SLPM flow rate independent of the inlet dew point and assists in the removal of other gases greatly increasing the life of the chemical scrubbers The M701H includes an oil free and diaphragm free pump plus scrubbers to remove 50 NO H2S 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 Dryer 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 to prevent the pump from starting against full head pressure The M701H is an ideal accessory to the Model 700 Mass Flow Calibrator or Model
