A20 Zero Air Generator

The A20 Zero Air generator utilizes catalytic reactor technology with load following operation which automatically adjusts to match demand and provides highly efficient hydrocarbon removal performance after catalyzer. On site convenience that improves lab efficiency – no more waiting for delivery, no more switching empty units, no more recalibrating new cylinders. Just plug it in and you're all set.

  • Compact, stackable bench-top or wall-mountable units save valuable bench space; wheels provide easy mobility.
  • High Performance
  • Low maintenance
  • Economical - more cost effective than other gas supply methods
