In the grand scheme of compressed air systems, Receiver Tanks are an oft overlooked component to a well designed system. The following video discusses when to use a secondary receiver tank and how to set one up. Enjoy!

What about wet and dry tanks? How are they manufacture what is the application, what is the life, how often they need certification, can I do welding if a leg breaks, What is the correct size how to determine the size need base on the compressor Hp. or Rated Flow taken from compressor Name Plate.
Wet tanks are placed immediately after the air compressor and serve to remove a lot of the initial moisture from the air. A wet tank is also referred to as a “supply” receiver. A dry tank is placed after the dryers and filters to server as a “demand” receiver.
The following questions would be questions that are better answered by a receiver tank manufacturer, but in general, I assume those answers vary quite a bit based on the use of the receiver, what kind of welding you may perform.
When determining the size of an air receiver, the following formula is used. Note that time, air demand and pressure drop are taken into consideration, which will be different for each customer or application.
T x C x Pa
V= ————-
P1-p2
V = Receiver volume, ft3
T = time allowed (minutes) for pressure drop to occur
C = Air Demand, cfm of free air
Pa = Absolute atmospheric pressure, psia.
P2= Final receiver pressure, psig
