Simple and quick to install |
Simple to operate, maintain and repair |
Manual and automatic operation |
Low installation, operating and maintenance costs |
Does NOT require multiple air connections |
Does NOT require a high pressure compressor |
Does NOT require motor driven mechanical equipment |
Does NOT require stiffeners for stability of high sections |
Does NOT require accurate foundation tolerances |
Does NOT require vertical side walls |
Does NOT suffer from leaking seals between sections |
Does NOT require sub-structures |
