An air separator for separating at least one constituent element from air delivered from an air source by a pair of adsorption beds utilizes a control box and assembly of working components arranged in such a relationship to one another within the control box so as to facilitate service and maintenance of the air separator. The working components of the air separator include filtering componentry, a pressure regulator, a pair of feed valves, a pair of waste valves, a pair of product and equalization valves and a product flow controller operatively connected in flow communication with one another for routing the source air through the separator and which are arranged in a substantially vertical plane within the control box. Because the working components are arranged in a generally planar arrangement, each of the working components is readily and easily accessible.

In a pressure swing adsorption apparatus including a pair of adsorbers each having an inlet and an outlet and adapted to fractionate at least one constituent from a gaseous mixture delivered from a feed stream by sequentially directing the gaseous mixture from the feed stream into the inlet of one adsorber so that said one adsorber performs adsorption while simultaneously purging the other adsorber of adsorbed constituent with product gas withdrawn from the outlet of the one adsorber and then directing the gaseous mixture from the feed stream into the inlet of the other adsorber so that said other adsorber performs adsorption while simultaneously purging the one adsorber of adsorbed constituent of product gas withdrawn from the outlet of the other adsorber wherein the apparatus includes feed and waste valving means associated with the inlets of the adsorbers to which the gaseous mixture is selectively routed to the inlet of one or the other adsorber for the production of product gas and through which product-depleted waste gas is discharged from the adsorber being purged and a purge loop and equalization valving means associated with the outlets of the adsorbers permitting the adsorbers to communicate with one another through the outlets thereof for the purposes of purging one and then the other of the adsorbers and for equalizing the internal pressure of the adsorbers between preselected stages of adsorber operation, the improvement comprising: a base; an elongated control box for housing the feed and waste valving means of the apparatus, said control box being directly mounted upon said base so that its longitudinal axis is oriented generally vertically and including a substantially planar back oriented generally vertically, the valving means of the apparatus are supportedly attached to said planar back in a substantially coplanar and vertical arrangement facilitating service and maintenance of said valving means, and said pair of adsorbers include a pair of towers directly mounted upon said base and oriented in a generally vertical, side-by-side arrangement and positioned in such a relationship with the control box so that the back panel of the control box is positioned adjacent and so as to span the width of the adsorber towers, the towers and the control box being attached to one another so that the vertical stability of each of the towers and control box contributes to the vertical stability of each of the other of the towers and control box.
