Each contactor bed has an inlet and an outlet in communication with the fluid flow inlet and fluid flow outlet, respectively, of the housing and each of the contactor beds includes a damper assembly pivotally disposed within its inlet. As the gas flow rate through the apparatus changes, individual contactor beds can be removed from or brought onto stream by closing or opening selected damper assemblies.
