Where space does not permit the installation of the required capacity accumulator, a smaller accumulator may be used by connecting it to a gas bottle(s) that can be located in a nearby spot where space is available. In some cases, an accumulator and gas bottle combination may be lower in cost, especially with large capacity applications.


  • Shell – high strength alloy steel, SA-372, exterior coated with primer.
  • Ports – steel
