Type III berms
employ four separate air chamber tubes to form the inflatable berm
or dike. These are positioned within the liner retention loops and
filled with air using the inflation nozzle provided. Use a high
volume, low pressure and non-sparking air source. Both the nozzle
and each tube are equipped with a 2.0 psi relief valve to prevent
over-pressurization. |

The type III air
inflation tubes are constructed of a special reinforced elastomer
laminate. This material is designed to provide abrasion resistance,
low temperature flexibility and excellent air retention (low
diffusion). However, these inflation tubes do not exhibit quite the
same outstanding chemical resistance as the unique type III black
liner material. Avoid prolonged contact between the inflation tubes
and any strong acids, alkalies or ketones. |

Type III berm
inflation is easily accomplished with the low pressure fan, blower,
foot pump or vehicle exhaust. Standard equipment includes a filling
nozzle which couples to each tube's inflation valve and incorporates
a 2 psi pressure relief feature. Each of the four type III tubes is
outfitted with it's own redundant relief valve to further protect
against over-pressurization. FPI also offers a very handy Electric
Inflator which operates on 110v AC and inflates or deflates the Type
III air tubes very quickly and safely. |
