Dynamically balanced at the required speed, complete with supports and tow couplings, it can be made with diameters and lengths as per the specifications listed below. Equipped with multivalve system: each air chamber has its own valve to ensure expansion, and if one gets damaged, the whole stays inflated; or the single valve system: each air chamer is connected to the other through a hole to ensure an equal expansion.
