Twin Air
Twin Air Technology® disposes of the use of a singular primary chamber, replaced by two equally sized left and right chambers running the full length of the board, segmented by a unique narrow centre hollow void, constrained by an outer compression-band. The resulting board, is super rigid achieved in part by limiting the width of the two conjoined chambers, secured by an extremely firm fitting outer compression band, which further adds an additional outer layer of protection to the seams of the chambers.
By conjoining x 2 narrow chambers, flex is significantly reduced as a consequence of reducing the total surface area of each. Long and narrow is simply stiffer, than long and wide. In tests, a ‘regular’ inflatable with a 75 kg static load bends by 9 cm but by only 3 cm with Mistral’s Twin Air Technology®.
The resulting compression of the two chambers, forms a narrow void along the centre line, into which a uniquely designed US fin-box is pushed and retained by friction. Featuring a stainless steel track and injection moulded stem, the stem is pushed between the two chambers and retained by friction alone – no fin box needs to be permanently secured to the board. Consequently, the fin can be placed in any number of different positions and any USB fin can fitted. A secondary box can be positioned mid centre of the board, to act as a mini-daggerboard in the case of Windsurfing.
With an equal 50/50 split of air reserve between the two primary chambers, in the event of one of the chambers being compromised, the other provides more than enough volume of air to provide adequate buoyancy for the paddler to make it to safety, exceeding all other inflatable capabilities on the market.
Although each board has its own valve, through the use of a ‘Y’ joiner, the pump can inflate both chambers simultaneously to equal pressures, so as there is no need to inflate the chambers separately. This is also important to arrive at the same PSI for each chamber.
You can watch the following video about the Twin Air Technology and how it works in a windsup inflatable board.
