The Zero Air generator range uses new catalyst technology to produce hydrocarbon-free air at a purity of less than 0.1 ppm. Models available from 1 to 80 lpm. Features 3-minute start-up time and low power consumption. Ideal for gas chromatography and emissions analyzers. Available in bench top and rack mount configurations.

The Zero Air generator is different from any other currently on the market. It utilizes catalytic conversion technology that allows the removal of hydrocarbons within a few minutes of start-up. The process is as follows: Compressed air (1) is fed into the system through a filter which removes particulate and bulk moisture via an autodrain. The air is passed over a low power heater element (2) before coming into contact with the catalytic convertor (3). At this point any hydrocarbons present are cracked before reforming into trace levels of carbon dioxide and moisture. The now hydrocarbon-free air is passed through a cooler (4) to return the air to ambient temperature and allow the outlet filter (5) to work efficiently.
