Collection: Morganton Air Compressor Tanks

Morganton builds ASME Section VIII Division 1 pressure vessels in Marion, North Carolina, under the Baglioni group. The tanks are U-stamped and National Board registered, and the shop sizes typically carry a 200 PSI maximum allowable working pressure, which covers any two stage piston or rotary screw you are likely to put in front of one.

Sizing is arithmetic, not opinion. Figure about 4 gallons of receiver per CFM for a reciprocating compressor and about 2 gallons per CFM for a rotary screw. A 25 HP screw making 100 CFM wants somewhere near 200 gallons. A 5 HP two stage making 17 CFM is well served by 60 to 80. Vertical tanks give the capacity back in floor space, which matters in a two bay shop. Horizontal tanks sit lower, mount easier, and are simpler to drain and inspect.

Two things to settle before you order

First, a receiver ships as a bare vessel. The gauge, the safety relief valve and the drain are separate line items, and the relief valve has to be sized to the compressor feeding the tank, not to the tank itself. People skip this and end up with a code problem sitting on a perfectly good vessel.

Second, a tank is not a capacity fix. Storage smooths spikes. It does not add CFM. If your compressor already runs loaded most of the hour, bolting on another 240 gallons buys a couple of minutes and then you are in the same hole you started in. Start with the storage sizing article and our air receiver tank guide. If you are replacing an older vessel, check whether rust has already made the decision for you.
