The MegaTorr PS7 Series Getter and Adsorber Gas purifiers utilize a combination of heated getter and ambient catalytic-adsorption processes to provide ultra-high purity Hydrogen gas. Outlet impurity levels for O₂, CO, CO₂, H₂O, CH₄, NMHC, and N₂.

Two ambient temperature adsorber vessels removes O₂, CO, CO₂ and H₂O while the downstream getter vessel, operated at an elevated temperature, eliminates N₂ and CH₄. The two adsorber vessels alternate between purify and regeneration mode providing continuous purification. Adsorber regeneration is accomplished by backflushing with purified hydrogen at elevated temperatures.
