Zero Air Generators

zero air generatorThe Environics® Series 7000 Zero Air Generators are easy to install, require minimal upkeep and are safer, easier and less costly than high pressure gas cylinders.

The Zero Air Generators are capable of continuous delivery of up to 20 standard liters per minute (SLPM), 30 pounds per square inch (PSI) of dry, contaminant-free air, with <0.02 ppm Hydrocarbons (optional).  The ZAG will produce ultra high purity zero grade air either from an existing compressed air source or as a powerful stand-alone unit.  The air is a perfect method for generating zero reference calibration gas, ultra-pure combustion air for flame ionization detector (FID), service air for pneumatically operated valves, hydrocarbon free chromatography use and general laboratory use.

The output from the ZAG provides a stable and repeatible air supply for comparable results regardless of location making it ideal for mobile lab.

Many laboratories purchase expensive high pressure Zero Air cylinders. While this method works, it is safer, more cost effective and more repeatable to use an in house generator. Your investment will quickly pay for itself.

The Zero Air Generator includes a color-changing moisture indicator to alert you to the presence of water vapor.  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 ZAG also includes with dual pressure regulation for enhanced performance.

Recommended ZAG Maintenance Schedule

Assuming average use and conditions, the recommended maintainence cost is about $200 per year.

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.

As a reminder, it is important that the drain be free of obstructions.  Connect a line to the drain port and route to a water collection container.
