A stationary air tank (also called an air receiver) is an ASME-rated steel pressure vessel installed between an air compressor and its distribution piping to store compressed air, smooth out pressure pulsations, reduce compressor cycling frequency, and allow moisture to condense out before air reaches downstream equipment. Speedaire's stationary tanks are built and stamped to ASME Section VIII standards specifically for use as air receivers, rated for a maximum working pressure of 200 psi.
Facilities engineers, compressed air system designers, and maintenance teams rely on stationary air tanks wherever a compressor needs a buffer volume to handle peak demand without excessive on/off cycling — nearly every fixed shop, plant, or facility compressed air system includes one sized to the compressor's output and the site's air consumption pattern. Their ASME Section VIII stamped construction, code-required safety documentation, and available vertical or horizontal orientations to fit different floor space constraints make them a standard, code-compliant component of virtually all stationary compressed air installations.
Common configuration: 30 to 240 gallon capacity, vertical or horizontal tank orientation, welded carbon steel construction, ASME U Stamp certification (some larger tanks also carry UM Stamp), and a 200 psi maximum operating pressure rating. NPT threaded ports accommodate inlet, outlet, drain, safety valve, and gauge connections.
