The AFS WILF wing has a one pump system. This system is a pipe with a valve added to it to cut or release the air between the central bladder and the bladder. This system is very useful for inflating and deflating the wing.
When it’s time to inflate your wing to go in the water, the one pump will save you time. Why? Well, quite simply, because with a single inflation valve and the one pump you can inflate both bladders: the leading board and the central bladder. There is an air transmission through the one pump.
Once your wing is well inflated, do not hesitate to close the valve of one pump in order to keep one bladder inflated if you ever pierce the other while sailing.
When you deflate the wing, you will be able to block the air. The flap system will allow you to cut the circulation between the central batten and the leading board (as after inflation) and when you are going to store your equipment you will be able to deflate the leading board first, roll up the ears one after the other and keep the central bladder inflated to optimize the storage.
Don’t hesitate to remove a little pressure before and to close again after to avoid having too much tension in the seams.
This technique will allow you to store your equipment more quickly and easily and especially to maintain the wing over time by avoiding folding it in all directions to fit it into the bag.
