701H High Performance Zero Air System

By: Teledyne Instruments API

The Model 701H is an excellent source of high purity zero air for all your process and analytical instrument needs. It is the ideal zero air source for ambient background monitoring applications using highly sensitive analyzers
such as the model 100EU, 200EU and 300EU trace gas analyzers. It also may be used as a source of purge air for permeation tube ovens or burner air for FID analyzers.

The regenerative, heatless dryer removes water and produces gas with a dewpoint of less than -25°C (dependant on flowrate). and assists in the removal of other gases, greatly increasing the life of the chemical scrubbers.
