Zero Air Generator

Series 7000 Zero Air Generator

The Environics® Series 7000 Zero Air Generator is a 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 Environics ZAG will produce high purity zero air from your dry compressed air source, eliminating the need for expensive, dangerous and bulky gas cylinders. Installation is as simple as connecting to a standard compressed air line and an electrical outlet.

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 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. 

The Series 7000 consists of scrubbers to remove SO2, NO, NO2, O3 and H2S. Optional scrubbers are available to remove CO and Hydrocarbons.

Operation of the system has been simplified so that the operator can set the output pressure desired through a regulator on the front panel of the system. The output pressure gauge is located to accurately reflect the output pressure of the system.

The Zero Air Generator is designed to fit into a 19" rack with optional slides or used in a portable mode.


Recommended ZAG Maintenance Schedule (assuming average use and conditions)

In order to keep your ZAG working at the highest level, we recommend the following maintenance schedule, assuming average system conditions and use.

  •  Fan filter should be cleaned by blowing out the filter monthly.

  • The pollution scrubber/converter and secondary scrubber media should be replaced yearly.

  • The input and output particle filters should be replaced yearly.
