ABSTRACT:
A reactivateable adsorption filter assembly comprises an adsorption filter element, a storage vessel in which is stored filtered fluid, a flow restrictor to restrict the flow of fluid between the adsorption filter element and the storage vessel and a purge valve on the inlet side of the adsorption filter element to selectively connect the filter assembly to a source of fluid at a low pressure, the arrangement being such that when the purge valve is opened to said source of fluid at low pressure filtered fluid containing adsorbate at a very low partial pressure flows back from the storage vessel through the adsorption filter element thereby reactivating said adsorption filter element.
