Powerful Stand Alone Zero Air Generator!
Featured Product from Environics, Inc.
Series 7000 Stand-Alone Zero Air Generator
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.
The ZAG now includes with dual pressure regulation for enhanced performance.
The Series 7000 consists of an oil-less piston pump and scrubbers to remove SO2, NO, NO2, O3 and H2S. Optional scrubbers are available to remove CO and Hydrocarbons.
A ballast tank is standard in the system. It extends both the pump and scrubber life by cycling the pump automatically only as needed.
The Series 7000 offers automatic pneumatic control. It will automatically turn on and off based on the demand of the system that it is supporting.
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. Strict attention has been paid to the weight of all components to make this system as light as possible.
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.

About Environics - World Leader in Gas Mixers, Gas Dilution and Calibration Systems
Environics is a world leader in computerized gas flow instrumentation. Our headquarters for design, manufacturing, sales and service is located in a modern 11,000 square foot facility in Tolland, Connecticut. We are ISO 9001 certified, having received ISO 9001 Quality Systems Certification in April, 1997.
We are a profitable, privately held company, founded in 1986 and incorporated in the State of Delaware. As of April 2011, we are a Women Owned business, certified through the Woman Owned Small Business Program run by the United States SBA. Our five-year projections show continued growth through the introduction of new products and product innovations. All service is handled factory direct. Sales are handled direct and by selected manufacturers representatives and distributors worldwide
Our gas mixing technology is based on very precise control of thermal mass flow controllers (MFCs). Normally, thermal MFCs offer an accuracy +/- 1% of full-scale flow. However, when combined with Environics computerization and calibration, this accuracy specification is improved to +/- 1% of setpoint. The Full-scale error vs. Setpoint error document shows the 10x improvement in accuracy of a thermal MFC when using Environics controlling technology. Our calibrators and dilution systems exceed the accuracy required by the EPA for Ambient Calibrators (ref: Method 205, 40CFR51, 40CFR60, 40CFR75). For more technical information, see our Technical Documents section, which contains current articles and CFR's pertinent to our technologies.
We encourage you to challenge us with your most difficult requirements. We specialize in custom systems. We have thousands of systems in the field and have developed an extensive library of applications and solutions to meet our customers' needs. The application of our technology has enabled us to become the world leader in user-friendly computerized gas flow instrumentation.
