For sale is a Silvan 1,040 gallon compressed air accumulator tank. Here's the drawing: http://www.spvgtools.com/media/silvan/102-969.pdf 48 inches wide, 155 inches high. Dimensions are believed correct but subject to buyer verification. This is a SUPER NICE tank, no rust of any significance, kept at a water/air purification plant and holding ultra-filtered compressed air, inside, at a contact lens manufacturer. A very rare find. Always inspected by the boiler marshal. Kept in pristine condition by a deep pocketed corporation. WARNING: There is DELAYED REMOVAL on this tank and it is supposed to be released to me on April 14, because they want to continue using it to operate their boilers, water purification equipment and whatnot. This means that you will NOT be able to take possession of it until it is released to me. I am a machinery mover and can deliver it to your shop near Chicago for an ADDITIONAL fee.
