This ChromGas zero air generator incorporates three stages:

• A 0.5 mm coalescing inlet filter removes particles, oil, and water
• A heated catalyst removes hydrocarbons
• A 0.01 mm cellulose fibre outlet filter removes residual particulate material from the product air stream

A hazard-free and economical alternative to high-pressure gas cylinders, this unit should pay for itself in a year or two.
