The Environics® Series 7000 Zero Air Generator is an ultra high purity air generator system that is capable of continuous delivery of up to 20 standard liters per minute (SLPM), 30 pounds per square inch (PSI) of dry, contaminant-free air. The ZAG is a powerful stand-alone unit, so there is no need for you to worry about an external compressed air supply or dangerous and expensive gas cylinders.
The air is suitable for use as: a zero reference calibration gas, ultra-pure combustion air for flame ionization detector (FID), and service air for pneumatically operated valves. The system is capable of delivering air free from water vapor, particulates, sulfur dioxide (SO2), Hydrogen Sulfide (H2S), Oxides of Nitrogen (NO), Nitrogen Dioxide (NO2), Ozone (O3), Carbon Monoxide (CO) and Hydrocarbons (HC).
The state-of-the-art PSA molecular sieve removes water and produces air with a dew point of less than -30°C. An adjustable drain interval negates the potential of excess water build-up. The Series 7000 is available with an optional dew point transmitter.
The Zero Air Generator now includes a color-changing moisture indicator (visible on the front panel, see updated P&ID below). If water vapor is present, the indicator will change from white to blue. When the water vapor is removed, the indicator will revert to its white color.
