Air Receivers/Vacuum Tanks Air Receivers and Vacuum Tanks store energy generated compressed air or vacuum at one time for use at a later time. Air Receivers/Vacuum Tanks are used for any pneumatic operation where compressed air or vacuum are required to perform a specific operation through a variable input output valve on the respective tank. Since the air is in compressed form it will exert varying amounts of pressure on the walls of the tank or vessel. Engineered Pressure Vessels carefully designs and fabricates ASME air receivers and vacuum tanks to meet the rigorous demands of the process industry. We offer metals and composites in the manufacturing process of our coded tanks.
