ABSTRACT:
The inflatable grain storage apparatus provides a truly portable inflatable and collapsible structure. The apparatus structure is fully integral. The apparatus is importantly bi-inflatable, whereby the reversible air pump air delivery and removal is via a Y with valve that provides for filling and emptying the spine and straight supports and also the structure interior separately or cumulatively. This hastens filling and ensures proper filling of the spine and straight supports without potential kinking or delays. The floor is importantly reinforced with bi-directional straps and is comprised of heavier material than are the above moisture and material proof components.
