Fully Regenerable Pressure Swing Adsorption (PSA) System

Pall’s Chemical, Biological, Radiological & Nuclear protection system (CBRN) is an effective tool in removing chemical warfare agents from contaminated air.  The principal part of the unit is a regenerable pressure swing adsorption (PSA) system which offers full protection against all known and potential threats, unlike traditional carbon technology.
